HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR


S-1111/1121 Series

The S-1111/1121 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption developed based on CMOS technology. A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realize high-density mounting. The lineup includes the S-1111 and S-1121 Series, which differ in pin configuration.

„ Features
• Output voltage: • High-accuracy output voltage: • Low dropout voltage: • Low current consumption: • High peak current capability: • Built-in ON/OFF circuit: • High ripple rejection: • Built-in overcurrent protector: • Small package: • Lead-free products 1.5 V to 5.5 V, selectable in 0.1 V steps. ±1.0% 200 mV typ. (3.0 V output product, IOUT = 100 mA) During operation: 35 μA typ., 65 μA max. During shutdown: 0.1 μA typ., 1.0 μA max. 150 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1 Ensures long battery life. 70 dB typ. (at 1.0 kHz) Overcurrent of output transistor can be restricted. SOT-23-5

*1. Attention should be paid to the power dissipation of the package when the output current is large.

„ Applications
• Power supply for battery-powered devices • Power supply for personal communication devices • Power supply for home electric/electronic appliances • Power supply for cellular phones
