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 small SOT-23-5 and 5-Pin SON(A) packages 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: 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. *1 150 mA output is possible (@ VIN VOUT(S) + 1.0 V) Ensures long battery life. 70 dB typ. (@ 1.0 kHz) Overcurrent of output transistor can be restricted. SOT-23-5, 5-Pin SON(A)
*1. Attention should be paid to the power dissipation of the package when the output current is large.
