s-1135 series www.sii-ic.com high ripple-rejection low dropout middle output current cmos voltage regulator ? seiko instruments inc., 2008-2010 rev.2.0 _00 seiko instruments inc. 1 s-1135 series, developed using the cmos tec hnology, is a positive voltage regulator ic which has the low dropout voltage, the high-accuracy output voltage and the low current consumption (300 ma output current). a 1.0 f small ceramic capacitor can be used. it oper ates with low current consumption of 45 a typ. the overcurrent protection circuit prev ents the load current from exceeding the capacit ance of output transistor. the power-off circuit ensures longer battery life. various capacitors, also small ceramic capacitors, can be used for this ic more than for the conventional regulator ics which have cmos technology. furthermore a small sot-89-5, sot-23-5, and hs nt-6a packages realize high-density mounting. ? features ? output voltage: 1.0 v to 3.5 v, selectable in 0.05 v step. ? low equivalent series resistance c apacitor : ceramic capacitor of 1.0 f or more can be used as the i/o capacitor. ? wide input voltage range: 1.5 v to 5.5 v ? high-accuracy output voltage: 1.0% (1.0 v to 1.45 v output product : 15 mv) ? low dropout voltage: 160 mv typ. (pr oducts having the out put of 2.6 v, i out = 300 ma) ? low current consumpti on: during operation: 45 a typ., 65 a max. during power-off: 0.1 a typ., 1.0 a max. ? output current: possible to output 300 ma (at v in v out(s) + 1.0 v) *1 ? high ripple rejection: 70 db typ. (at 1.0 khz, v out = 1.0 v) ? built-in overcurrent protection circuit: limits overcurrent of output transistor ? built-in power-off circuit: ensures long battery life. ? discharge shunt circuit can be selected. ? resistor is selectable in pull-up or pull-down ? lead-free, sn 100%, halogen-free *2 *1. attention should be paid to the power dissipation of the package when the out put current is large. *2. refer to ? ? product name structure ? for details. ? applications ? power supply for battery-powered devices ? power supply for cellular phones ? power supply for portable equipment ? packages ? sot-89-5 ? sot-23-5 ? hsnt-6a

(1) output voltage vs. output current (when load current increases) (ta = 25 c) ? in ?? characteristics (typical data) ?, in order to protect the output transistor against an excessive output current and shor t circuiting between the vout and vss pins. the current (i short ) when the output pin is short- circuited is internally set at approx. 100 ma (typ.), and the normal value is restored for the output volt age, if releasing a short circuit once. caution using the overcurrent protection circuit is to protect the output transistor from accidental conditions such as short circuited load and the rapid and large current flow in the large capacitor. the overcurrent protection circuit is not suitable for use under the short circuit status or large current flowing (300 ma or more) that last long. 6. pull-down / pull-up resistor (s-1135 series a / c / e / g types) in the s-1135 series a / c / e / g types, the on / off pin is internally pulled up to vin or pulled down to vss, so the vout pin is in the v ss level when in the floating status. note that the ic?s current c onsumption increases as much as current flows into the pull-up / pull-down resistor of 2.2 m (typ.) when; the on / off pin is connected to vin in the a / c type, the on / off pin is connected to vss in the e / g type.
