description the 66150 series of positive fixed and adjustable regu- lators is designed to provide up to 1.5a output with high current, high accuracy, and extremely low dropout voltage performance. these regulators feature 300 to 350mv (full load) dropout voltages, and very low ground current. although designed for high current loads, these devices are also useful in lower current, extremely low dropout- critical systems, where their minimal dropout voltage and ground current values are important characteristics. the 66150 is fully protected against overcurrent, re- versed input polarity (or reversed battery connection), re- versed lead insertion, over-temperature operation, and tran- sient voltage spikes (positive or negative). five pin fixed voltage versions feature logic level on/off control and an error flag which signals whenever the output falls out of regulation. on the 66151 and 66152, the enable pin may be tied to v if it is not required for on/off control. in the 66150 is available in 3-pin and 5-pin to-220 and surface mount to-263 packages. application high efficiency linear regulators post regulators for switching supplies high efficiency "green" computer systems battery powered equipment automotive electronics g m 4 3 1 features fixed and adjustable v oltage versions output current up to 1.5a low dropout voltage 350mv @ 1.5a low ground current accurate 1% guaranteed t olerance extremely fast transient response reverse-battery protection "load dump" protection zero-current shutdown mode(5-pin versions) error flag signals output out-of-regulation (5-pin versions) typical applica tion circuits + 5 v 5% 66150 - 3.3 3.3 v 1% @1.5a 47f figure 1. fixed voltage v ersion + + v in v = 1.24v x [1 + (r1 /r2)] out v out r1 r2 figure 2. adjustable voltage v ersion 10f 22f FC66150~3 1.5a ultra low - droupout voltage regulator

application informa tion the 66150 series is high performance with low- dropout voltage regulators, suitable for all moderate to high-current voltage regulator applications. their 350mv dropout voltage at full load makes them espe- cially valuable in battery powered systems and as high efficiency noise filters in "post-regulator" applications. unlike older npn-pass transistor designs, for which where the minimum dropout voltage is limited by the base-emitter voltage drop and collector-emitter satura- tion voltage, dropout performance of the pnp output of these devices is limited merely by the low v satura- ce tion voltage. a trade-off for the low dropout voltage is a varying base drive requirement. but, pnp process reduces this drive requirement to merely 1% of the load current. the 66150 series of regulators is fully protected from damage due to fault conditions. current limiting is provided. this limiting is linear, and output current un- der overload conditions is constant. thermal shutdown disables the device when the die temperature exceeds the 125c maximum safe operating temperature. transient protection allows device (and load) survival even when the input voltage spikes between -20v and +60v. when the input voltage exceeds about 35v to 40v, the overvoltage sensor temporarily disables the regulator. the output structure of these regulators al- lows voltages in excess of the desired output voltage to be applied without reverse current flow. 66151 and 66152 versions offer a logic level on/off control: when disabled, the devices draw nearly zero current. an additional feature of this regulator family is a com- mon pinout: a design's current requirement may change up or down yet use the same board layout, as all of these regulators have identical pinouts. + + v in in o u t g n d v o ut figure 10. linear regulators require only two capacitors for operation. thermal design linear regulators are simple to use. the most com- plicated design parameters to consider are thermal characteristics. thermal design requires the follow- ing application-specific parameters: maximum ambient temperature, t a output current, i out output voltage, v out input voltage, v in first, we calculate the power dissipation of the regu- lator from these numbers and the device parameters from this formula: where the ground current is approximated by 1% of i. out then the heat sink thermal resistance is determined with this formula: where t 125c and q is between 0 and j(max) cs 2c/w. the heat sink may be significantly reduced in applications where the minimum input voltage is known and is large compared with the dropout volt- age. use a series input resistor to drop excessive voltage and distribute the heat between this resistor and the regulator. the low dropout properties of pnp regulators allow very significant reduc- tions in regulator power dissipation and the associ- ated heat sink without compromising performance. when this technique is employed, a capacitor of at least 0.1f is needed directly between the input and regulator ground. p = i (1.01v - v ) d out in out q = ( q sa jc + q ) cs t - t a j(max) p d fc 6615 0 ~ 3 1 . 5 a u l tra lo w - d rou po ut v oltage re g u l at or
capacitor requirements for stability and minimum output noise, a capacitor on the regulator output is necessary. the value of this ca- pacitor is dependent upon the output current; lower cur- rents allow smaller capacitors. 66150 regulators are stable with the minimum capacitor value of 10f at full load. this capacitor needs not be an expensive low esr type: aluminum electrolytics are adequate. in fact, extremely low esr capacitors may contribute to insta- bility. t antalum capacitors are recommended for sys- tems where fast load transient response is important. where the regulator is powered from a source with a high ac impedance, a 0.1f capacitor connected be- tween input and gnd is recommended. this capacitor should has good characteristics to above 250khz. minimum load current the 66150 regulators are specified between finite loads. if the output current is too small, leakage cur- rents dominate and the output voltage rises. the 5ma minimum load current swamps any expected leakage current across the operating temperature range. adjustable regulator design the adjustable regulator versions, 66152 and 66153, allow programming the output voltage anywhere between 1.25v and the 26v maximum op- erating rating of the family. t wo resistors are used. resistors can be quite large, up to 1m w , because of the very high input impedance and low bias current of the sense comparator: the resistor values are cal- culated by: where v is the desired output voltage. o figure 11 shows component definition. applications with widely varying load currents may scale the re- sistors to draw the minimum load current required for proper operation (see above). error flag 66151 and 66153 versions feature an error flag, which looks at the output voltage and signals an error condition when this voltage drops 5% below its expected value. the error flag is an open- collector output that pulls low under fault conditions. it may sink 10ma. low output voltage signifies a number of possible problems, including an overcurrent fault (the device is in current limit) and low input voltage. the flag output is inoperative dur- ing overtemperature shutdown conditions. enable input 66151 and 66152 versions feature an enable (en) input that allows on/off control of the device. special design allows "zero" current drain when the device is disabled -only microamperes of leakage current flows. the en input has ttl/cmos compat- ible thresholds for simple interfacing with logic, or may be directly tied to 30v. enabling the regulator requires approximately 20a of current. r1 = r2 ( -1) v out 1.240 figure 11. adjustable regulator with resistor + + v in v = 1.24v x [1 + (r1 /r2)] out v out r1 r2 22f 66152 10f fc 6615 0 ~ 3 1 . 5 a u l tra lo w - d rou po ut v oltage re g u l at or
