high ripple-rejection low dropout cmos voltage regulator s-1165 series rev.4.0 _00 seiko instruments inc. 12 ? operation 1. basic operation figure 11 shows the block diagram of the s-1165 series. the error amplifier compares the reference voltage (v ref ) with v fb , which is the output voltage resistance- divided by feedback resistors r s and r f . it supplies the output transisto r with the gate voltage necessary to ensure a certain output voltage free of any fluctuations of input voltage and temperature. reference voltage circuit vout *1 *1. parasitic diode vss vin r s r f error amplifier current supply v ref ? + v fb figure 11 2. output transistor the s-1165 series uses a low on-resistance p- channel mos fet as the output transistor. be sure that v out does not exceed v in + 0.3 v to prevent the voltage regulator from being damaged due to inverse current flowing from vout pin through a parasitic diode to vin pin.
high ripple-rejection low dropo ut cmos voltage regulator rev.4.0 _00 s-1165 series seiko instruments inc. 13 3. shutdown pin (on/off pin) this pin starts and stops the regulator. when the on/off pin is set to the shutdown level, the operation of all internal circuits stops, and the built- in p-channel mos fet output transistor between the vin pin and vout pin is turned off to substantially reduce the current consumption. the vout pin becomes the v ss level due to the internally divided resistance of several hundreds k between the vout pin and vss pin. the structure of the on/off pin is as shown in figure 12 . since the on/off pin is neither pulled down nor pulled up internally, do not use it in the floating st ate. in addition, note that the current consumption increases if a voltage of 0.3 v to v in ? 0.3 v is applied to the on/off pin. when the on/off pin is not used, connect it to the vss pin if the logic ty pe is ?a? and to the vin pin if it is ?b?. table 5 logic type on/off pin internal circuits vout pin voltage current consumption a ?l?: power on operating set value i ss1 a ?h?: power off stopped v ss level i ss2 b ?l?: power off stopped v ss level i ss2 b ?h?: power on operating set value i ss1 vss on/off vin figure 12 ? selection of output capacitor (c l ) the s-1165 series performs phase compensation using the internal phase compensator in the ic and the esr (equivalent series resistance) of the output capacitor to enable stabl e operation independent of changes in the output load. therefore, always place a capacitor (c l ) of 2.2 f or more between vout and vss pins. for stable operation of the s-1165 series, it is essential to employ a capacitor whose esr is within an optimum range. using a capacitor whose esr is outsi de the optimum range (approximately 0.5 to 5 ), whether larger or smaller, may cause an unstable output, resulting in o scillation. for this reason, a tantalum electrolytic capacitor is recommended. when a ceramic capacitor or an os capacitor with a lo w esr is used, it is necessary to connect an additional resistor that serves as the esr in series with the output capacitor. the required resistance value is approximately 0.5 to 5 , which varies depending on the usage conditions, so perform sufficient evaluation for selection. ordinarily, around 1.0 is recommended. note that an aluminum electrolytic capacitor may increas e the esr at a low temperature, causing oscillation. when using this kind of capacitor, perform thorough evaluation, including eval uation of temperature characteristics.
high ripple-rejection low dropout cmos voltage regulator s-1165 series rev.4.0 _00 seiko instruments inc. 14 ? precautions ? wiring patterns for the vin, vout and gnd pins should be designed so that the impedance is low. when mounting an output capacitor between the vout and vss pins (c l ) and a capacitor for stabilizing the input between vin and vss pins (c in ), the distance from the capacit ors to these pins should be as short as possible. ? note that the output voltage may increase when a series regulator is used at low load current (1.0 ma or less). ? this ic performs phase compensation by using an internal phase compensator and the esr of an output capacitor. therefore, al ways place a capacitor of 2.2 f or more between vout and vss pins. a tantalum type capacitor is recommended. moreover, to secure stable operation of the s-1165 series, it is necessary to employ a capacitor wi th an esr within an optimum range (0.5 to 5 ). using a capacitor whose esr is outside the opt imum range (approximately 0.5 to 5 ), whether larger or smaller, may cause an unstable output, resulting in oscillation. perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperat ure characteristics. ? the voltage regulator may oscillate when the im pedance of the power supply is high and the input capacitor is small or an input capacitor is not connected. ? the application conditions for the input voltage, output voltage, and load curr ent should not exceed the package power dissipation. ? do not apply an electrostatic discharge to this ic that exceeds the performanc e ratings of the built-in electrostatic protection circuit. ? in determining the output current, attention should be paid to the output current value specified in table 4 in the electrical characterist ics and footnote *5) of the table. ? sii claims no responsibility for any disputes arising out of or in connection with any infringement by products including this ic of patents owned by a third party.
