S-814 Series LOW DROPOUT CMOS VOLTAGE REGULATOR www.sii-ic.com SII Semiconductor Corporation, 1999-2015 Rev.3.1 01 The S-814 Series is a low dropout voltage, high output voltage accuracy and low current consumption positive voltage regulator developed utilizing CMOS technology. Built-in low ON-resistance transistors provide low dropout voltage and large output current. The ON/OFF circuit ensures long battery life. Various types of output capacitors can be used in the S-814 Series compared with the past CMOS voltage regulators. (i.e., Small ceramic capacitors can also be used in the S-814 Series.) The SOT-23-5 miniaturized package and the SOT-89-5 packages are recommended to use for configuring portable devices and large output current applications, respectively. Features Output voltage: 2.0 V to 6.0 V, selectable in 0.1 V step Output voltage accuracy: 2.0% Dropout voltage: 170 mV typ. (5.0 V output product, IOUT=60 mA) Current consumption: During operation: 30 A typ., 40 A max. During power-off: 100 nA typ., 500 nA max. *1 Output current: Possible to output 110 mA (3.0 V output product, V =4 V) IN *1 Possible to output 180 mA (5.0 V output product, VIN=6 V) Output capacitor: A ceramic capacitor of 0.47 F or more can be used. Built-in ON/OFF circuit: Ensures long battery life. Built-in short-circuit protection circuit 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 output current is large. *2. Refer to Product Name Structure for details. Applications Constant-voltage power source for battery-powered device, personal communication device, and home electric/electronic appliance.
