SUPER-SMALL PACKAGE CMOS VOLTAGE REGULATOR

The S-817 Series is a 3-terminal positive voltage regulator, developed using CMOS technology. Small ceramic capacitors can be used as the output capacitor, and the S-817 series provides stable operation with low loads down to 1 µA.

Compared with the conventional voltage regulator, it is of low current consumption, and with a lineup of the super small package (SNT-4A:1.2 x 1.6mm). It is optimal as a power supply of small portable device.

Features

• Ultra-low current consumption: Operating current: Typ. 1.2 µA, Max. 2.5 µA

• Output voltage: 1.1 to 6.0 V, selectable in 0.1 V steps.

• Output voltage accuracy: ±2.0

• Output current: 50 mA capable (3.0 V output product, VIN=5 V) *1

75 mA capable (5.0 V output product, VIN=7 V) *1

• Dropout voltage: Typ. 160 mV (VOUT = 5.0 V, IOUT = 10 mA)

• Low ESR capacitor Ceramic capacitor of 0.1 µF or more can be used as an output capacitor.

• Short circuit protection for: Series A

• Excellent Line Regulation: Stable operation at light load of 1 µA

• Lead-free product

*1. Attention should be paid to the power dissipation of the package when the load is large.

Applications

• Power source for battery-powered devices

• Power source for personal communication devices

• Power source for home electric/electronic appliances
