5.5 V INPUT, 300 mA VOLTAGE REGULATOR
Rev.2.3_00
The S-1135 Series, developed using the CMOS technology, 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 μF small ceramic capacitor can be used. It operates with low current consumption of 45 μA typ. The overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor. The ON / 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 HSNT-6A packages realize high-density mounting.

1.0 V to 3.5 V, selectable in 0.05 V step 1.5 V to 5.5 V ±1.0% (1.0 V to 1.45 V output product : ±15 mV) 160 mV typ. (2.6 V output product, IOUT = 300 mA) During operation: 45 μA typ., 65 μA max. During power-off: 0.1 μA typ., 1.0 μA max. Possible to output 300 mA (VIN ≥ VOUT(S) + 1.0 V)*1 A ceramic capacitor of 1.0 μF or more can be used. 70 dB typ. (1.0 V output product, f = 1.0 kHz) Limits overcurrent of output transistor. Ensures long battery life. Discharge shunt function “available” / “unavailable” is selectable. Pull-down / pull-up function “available” / “unavailable” is selectable. Ta = −40°C to +85°C
