BM9166

BM9166 250mA CMOS LDO GENERAL DESCRIPTION The BM9166 family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (<55uA typ.), low dropout voltage, and high output voltage accuracy. Built-in low on-resistance transistor provides low dropout voltage and large output current. A 2.2µF or greater can be used as an output capacitor. The SOT-23-3 miniaturized package are recommended for configuring portable devices and large current application, respectively. These robust devices are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back. www.DataSheet4U.com FEATURES Very Low Dropout Voltage Low Current Consumption: Typ. <55uA Output Voltage: 1.5V, 2.5V , 3.0V, 3.3V High Accuracy Output Voltage: +/- 1.5% Guaranteed >200mA Output Input Range of 1.8V to 7.0V Thermal Shutdown High PSRR to 60dB Compact Package: SOT-23-3, SOT-89 Factory Pre-set Output Voltages Short Circuit Current Fold-Back Low Temperature Coefficient APPLICATIONS Battery-powered devices , like DSC , MP3 , portable DVD Personal communication devices Home electric/electronic appliances PC peripherals ( PC card) , Hard-disc Pin define 3 1 2 1 2 3 SOT23-3 pin1 = GND , pin2 = Vout , Pin3 = Vin , SOT89 pin1 ＝GND pin2 = Vin pin3 = Vout 2004/8/30 www.digitalspirit.info Page 1 BM9166 250mA CMOS LDO BLOCK DIAGRAM IN OUT www.DataSheet4U.com Overcurrent Shutdown Therm al Shutdown R1 + Vref = 1.1...
