1 / 48 page  S-1135 Series www.sii-ic.com HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR © SII Semiconductor Corporation, 2008-2015 Rev.2.2_01 1 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. Features • Output voltage: 1.0 V to 3.5 V, selectable in 0.05 V step • Input voltage: 1.5 V to 5.5 V • Output voltage accuracy: ±1.0% (1.0 V to 1.45 V output product : ±15 mV) • Dropout voltage: 160 mV typ. (2.6 V output product, IOUT = 300 mA) • Current consumption: During operation: 45 μA typ., 65 μA max. During power-off: 0.1 μA typ., 1.0 μA max. • Output current: Possible to output 300 mA (VIN ≥ VOUT(S) + 1.0 V)*1 • Input and output capacitors : A ceramic capacitor of 1.0 μF or more can be used. • Ripple rejection: 70 dB typ. (1.0 V output product, f = 1.0 kHz) • Built-in overcurrent protection circuit: Limits overcurrent of output transistor. • Built-in ON / OFF circuit: Ensures long battery life. • Discharge shunt function is selectable. • Pull-up or pull-down resistor is selectable. • Operation temperature range: Ta = −40°C to +85°C • Lead-free, Sn 100%, halogen-free*2 *1. Attention should be paid to the power dissipation of the package when the output current is large. *2. Refer to “ Product Name Structure” for details. Applications • Power supply for battery-powered device • Power supply for cellular phone • Power supply for portable equipment Packages • SOT-89-5 • SOT-23-5 • HSNT-6A |
