The S-1200 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy developed based on CMOS technology.

Features

? Output voltage: 1.5 V to 5.5 V, selectable in 0.1 V steps.

? Low ESR capacitor can be used: A ceramic capacitor of 0.1 ?F or more can be used for the output capacitor.

? Wide input voltage range: 2.0 V to 10.0 V

? High-accuracy output voltage: ±1.0

? Low dropout voltage: 140 mV typ. (3.0 V output product, IOUT = 100 mA)

? Low current consumption: During operation: 18 ?A typ., 40 ?A max. During shutdown: 0.01 ?A typ., 1.0 ?A max.

? Output current: 150 mA output is possible (@ VIN ≥ VOUT(S) + 1.0 V)*1

? High ripple rejection: 70 dB typ. (@ 1.0 kHz, 1.5 V ≤ VOUT ≤ 3.0 V) 65 dB typ. (@ 1.0 kHz, 3.1 V ≤ VOUT ≤ 5.5 V)

? Built-in overcurrent protector: Overcurrent of output transistor can be restricted.

? Built-in ON/OFF circuit: Ensures long battery life.

? Small package: SOT-23-5, SNT-6A(H)

? Lead-free products

*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
