1 / 36 page Rev.1.1_00 ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR S-1206 Series Seiko Instruments Inc. 1 The S-1206 Series is a positive voltage regulator with ultra low current consumption, low dropout voltage, high output voltage accuracy, and 250 mA output current developed based on CMOS technology. I/O capacitors are as small as 0.1 µF. S-1206 Series operates at ultra low current consumption of 1.0 µA (typ.). The built-in low-on-resistance transistor realizes low dropout voltage and high output current. A built-in overcurrent protection circuit prevents the load current from exceeding the current capacitance of the output transistor. Three packages, SOT-23-3, SOT-89-3, and SNT-6A(H), are available. Compared with voltage regulators using a conventional CMOS process, more types of capacitors, including small I/O capacitors, can be used with the S-1206 Series. The S-1206 Series features ultra-low current consumption and comes in a small package, making them most suitable for portable equipment. Features • Output voltage : 1.2 to 5.2 V, selectable in 0.05 V steps. • Low equivalent series resistance capacitor can be used : A ceramic capacitor of 0.1 µF or more can be used for the I/O capacitor. • Wide input voltage range : 1.7 to 6.5 V • High-accuracy output voltage : ±1.0% (1.2 to 1.45 V output product : ±15 mV) • Low dropout voltage : 150 mV typ. (3.0 V output product, at IOUT = 100 mA) • Low current consumption : During operation : 1.0 µA typ., 1.5 µA max. • High output current : 250 mA output is possible. (3.0 V output product, at VIN ≥ VOUT(S) + 1.0 V) *1 • Built-in overcurrent protection circuit : Overcurrent of output transistor can be restricted. • Small package : SOT-23-3, SOT-89-3, 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 • Constant-voltage power supply for cellular phones • Constant-voltage power supply for portable equipments Packages Drawing Code Package Name Package Tape Reel Land SOT-23-3 MP003-Z MP003-Z MP003-Z − SOT-89-3 UP003-A UP003-A UP003-A − SNT-6A(H) PI006-A PI006-A PI006-A PI006-A |
