1/36 xc6215 series 0.8 a low power consumption voltage regulator with on/off switch general description the xc6215 series are highly precise, lo w noise, positive voltage ldo regulators manufactured using cmos processes. the series achieves very low supply current, 0.8 a (typ.) and consists of a reference volt age source, an error amplifier, a current foldback circuit, and a phase compensation circuit plus a driver transistor. ultra small packages usp-3, usp-4, uspn-4 and ssot-24, and small package sot-25 packages make high density mounting possible. therefore, t he series is ideal for applications where high dens ity mounting is required such as in mobile phones. output voltage is selectable in 0.1v in crements within a range of 0.9v ~ 5.0v by laser trimming the series is also compatible with low esr ceramic capacitors, which give added output stability. the current limiter's foldback circuit also operates as a shor t protect for the output current limiter and the output pin. furthermore, the ce function allows t he output of the regulator to be turned of f, resulting in greatly reduced power consumption. typical application circuit applications mobile phones cordless phones, wireless communication equipment portable games cameras, video recorders portable av equipment pdas features maximum output current : 200ma (300ma limit, typ.) @ v out =3.0v, v in =4.0v dropout voltage : 320mv @ i out = 100ma @ v out = 3.0v operating input voltage : 1.5v ~ 6.0v output voltage range : 0.9v ~ 5.0v (0.1v increments) highly accurate : set voltage accuracy 2% (1.5v 2/36 xc6215 series * for mounting intensity and heat dissipation, please refer to recommended mounting pattern and recommended metal mask when soldering the pad of usp-4. mounting should be electrically isolated or connected to the v ss (no.2) pin. pin number uspn-4 usp-3 usp-4 ssot-24 sot-25 pin name function 4 1 4 4 1 v in power supply 2 3 2 2 2 v ss ground 3 - 3 1 3 ce on / off switch 1 2 1 3 5 v out output - - - - 4 nc no connection designator description symbol description b ce logic = high active with no pull-down resistor type of regulator p 3 pin regulator with no ce pin (usp-3 only) ? output voltage 09 ~ 50 0.9 v ~ 5.0v, 0.1v step e.g. v out =3.0v =3, =0 output voltage accuracy 2 + 2 % accuracy e.g. v out =3.0v =3, =0, =2 gr-g usp-4 nr ssot-24 nr-g ssot-24 mr sot-25 mr-g sot-25 hr usp-3 (for the xc6215p series only) hr-g usp-3 (for the xc6215p series only) ?- packages taping type (*2) 7r-g uspn-4 pin configuration pin assignment product classification ordering information xc6215 ?????- ( *1 ) 2 1 3 3 vss vss vout vin usp-4 (bottom view) ssot-24 (top view) usp-3 (bottom view) sot-25 (top view) (*1) the ?-g? suffix indicates that the products are hal ogen and antimony free as well as being fully rohs compliant.

10/36 xc6215 series operational explanation notes on use xc6215b series (as for the xc6215p series, with no ce pin) 1. please use this ic within the stated absolute maximum ratings. the ic is liable to malfunction should the ratings be exceede d. 2. where wiring impedance is high, op erations may become unstable due to noi se and/or phase lag depending on output current. 3. as for the xc6215 series, internally achieved phase compensation makes a stabl e operation of the ic possible even when there is no output capacitor (c l ). in order to stabilize the v in ?s voltage level, we recommend that an input capacitor (c in ) of about 0.1 to 1.0 f be connected between the v in pin and the v ss pin. moreover, during transient response, so as to prevent an undershoot or overshoot, we recommend that the output capacitor (c l ) of about 0.1 to1.0 f be connected between the v out pin and the v ss pin. however, please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. the xc6215 series? regulator offers circuit protection by means of a built-in foldback circuit. when the load current reaches the current limit level, the fixed cu rrent limiter circuit operates a nd output voltage drops. as a re sult of this drop in output v oltage, the foldback circuit operates, the output voltage drops further and output current decreases. w hen the output pin is shorted, a current of about 50ma flows. the ic's internal circuitry can be operated or shutdown via the si gnal from the ce pin with the xc6215b series. in shutdown mode, output at the v out pin will be pulled down to the v ss level via r1 & r2. note that the xc6215 series? regulator is ?high active/no pull-down?, operations will become unstable with the ce pin open. we suggest that you use this ic with either a v in voltage or a v ss voltage input at the ce pin. if this ic is used with the correct specifications fo r the ce pin, the operational logic is fixed and the ic will operate normally. howeve r, supply current may increase as a resu lt of through current in the ic's intern al circuitry. |
