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 µF 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 µA typ., 40 µA max. During shutdown: 0.01 µA typ., 1.0 µA 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
