HIGH RIPPLE-REJECTION LOW DROPOUT CMOS VOLTAGE REGULATOR
S-T111 Series
The S-T111 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. Compared with the voltage regulators using the conventional CMOS process, a larger variety of capacitors are available, including small ceramic capacitors. A small SOT23-5 package realizes high-density mounting.
Features
1.5 V to 5.5 V, selectable in 0.1 V steps. ±1.0% 190 mV typ. (3.0 V output product, IOUT = 100 mA) During operation: 50 µA typ., 90 µA max. During shutdown: 0.1 µA typ., 1.0 µA max. *1 · High peak current capability: 150 mA output is possible (@ VIN VOUT(S) + 1.0 V) Ensures long battery life. · Built-in ON/OFF circuit: · Low ESR capacitor can be used: A ceramic capacitor of 0.1 µF or more can be used for the output capacitor. 80 dB typ. (@ 1.0 kHz) · High ripple rejection: Overcurrent of output transistor can be restricted. · Built-in overcurrent protector: SOT-23-5 · Small package: *1. Attention should be paid to the power dissipation of the package when the output current is large. · Output voltage: · High-accuracy output voltage: · Low dropout voltage: · Low current consumption:
