S-817 Series SUPER-SMALL PACKAGE CMOS VOLTAGE REGULATOR www.sii-ic.com SII Semiconductor Corporation, 1999-2015 Rev.6.2 01 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 A. Compared with the conventional voltage regulator, it is low current consumption, and with a lineup of the super small package (SNT-4A:1.2 mm 1.6 mm). It is optimal as a power supply of small portable device. Features Output voltage: 1.1 V to 6.0 V, selectable in 0.1 V step Output voltage accuracy: 2.0% Dropout voltage: 160 mV typ. (5.0 V output product, I = 10 mA) OUT Current consumption: During operation: 1.2 A typ., 2.5 A max. *1 Output current: Possible to output 50 mA (3.0 V output product, VIN=5 V) *1 Possible to output 75 mA (5.0 V output product, VIN=7 V) Output capacitor A ceramic capacitor of 0.1 F or more can be used. Built-in short circuit protection: Only S-817A Series Line regulation: Stable operation at low load of 1 A Operation temperature range: Ta = 40C to +85C *2 Lead-free, Sn 100%, halogen-free *1. Attention should be paid to the power dissipation of the package when the load is large. *2. Refer to Product Name Structure for details.
