Datasheet AS1375 1A Quiescent Current, 200mA LDO 1 General Description 2 Key Features Input Voltage: 2V to 5.5V The AS1375 low-power, positive voltage regulator is designed to deliver up to 200mA, while consuming only Low Dropout Voltage: 120mV 200mA load 1A (typ.) of quiescent current. The device is available Output Voltage Range: 1.2V to 5.0V (50mV steps) in fixed output voltages between 1.2V and 5.0V Max. Output Current: 200mA (programmable in 50mV steps). The input voltage ranges from 2V to 5.5V. Operation with large input to Very Low Quiescent Current: 1A output differential voltages is limited by the maximum Output Voltage Accuracy: 1% power dissipation available from package and Low Shutdown Current: 10nA (typ.) environment. Integrated Overtemperature/Overcurrent Protection The very-low dropout voltage prolongs battery life and allows high current in small applications when operated Under-Voltage Lockout Feature with minimum input-to-output voltage differentials. The Enable Input device features very stable output voltage, strict output Minimal External Components Required voltage regulation tolerances (1%), and excellent line- and load-regulation. Operating Temperature Range: -40C to +85C The device features integrated short-circuit and over 6-pin TDFN 2x2mm Package current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying. Thermal Protection shuts down the device when die temperature reaches 160C. This is a useful 3 Applications protection when the device is under sustained short circuit conditions. The device is perfectly suited for wireless handsets, smartphones, PDAs, MP3 players, and other battery- The AS1375 is available in an 6-pin TDFN 2x2mm operated handheld devices, where the regulators have package and is qualified for -40C to +85C operation. to be always on.
