S-818 Series www.ablic.com LOW DROPOUT CMOS VOLTAGE REGULATOR www.ablicinc.com ABLIC Inc., 2000-2015 Rev.3.1 02 The S-818 Series is a positive voltage regulator developed by CMOS technology and featured by low dropout voltage, high output voltage accuracy and low current consumption. Built-in low on-resistance transistor provides low dropout voltage and large output current. A ceramic capacitor of 2 F or more can be used as an output capacitor. An ON/OFF circuit ensures long battery life. The SOT-23-5 miniaturized package and the SOT-89-5 package are recommended 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, I = 60 mA) OUT 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 200 mA (3.0 V output product, V = 4 V) IN *1 Possible to output 300 mA (5.0 V output product, V = 6 V) IN Output capacitor: A ceramic capacitor of 2 F or more can be used. Built-in ON/OFF circuit: Ensures long battery life. Operation temperature range: Ta = 40 C to 85C *2 Lead-free, Sn 100%, halogen-free *1.
