HIGH RIPPLE-REJECTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1112/1122 Series
The S-1112/1122 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. Small SNT6A(H) (S-1112 Series only) and SOT-23-5 packages realize high-density mounting. In SOT-23-5, the lineup includes the S-1112 and S-1122 Series, which differ in pin configuration.
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 A typ., 90 A max. During shutdown: 0.1 A typ., 1.0 A max. High peak current capability: 150 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1 Ensures long battery life. Built-in ON/OFF circuit: Low ESR capacitor can be used: A ceramic capacitor of 0.47 F or more can be used for the output capacitor. 80 dB typ. (at 1.0 kHz) High ripple rejection: Overcurrent of output transistor can be restricted. Built-in overcurrent protector: SNT-6A(H)(S-1112 series only), SOT-23-5 Smal……
