2 / 11 page AS1375 1µA Quiescent Current, 200mA LDO www.austriamicrosystems.com/LDOs/AS1375 Revision 1.02 1 - 10 Data sheet 1 General Description The AS1375 low-power, positive voltage regulator is designed to deliver up to 200mA, while consuming only 1µA (typ.) of quiescent current. The device is available in fixed output voltages between 1.2V and 5.0V (programmable in 50mV steps). The input voltage ranges from 2V to 5.5V. Operation with large input to output differential voltages is limited by the maximum power dissipation available from package and environment. The very-low dropout voltage prolongs battery life and allows high current in small applications when operated with minimum input-to-output voltage differentials. The device features very stable output voltage, strict output voltage regulation tolerances (±1%), and excellent line- and load-regulation. The device features integrated short-circuit and over 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 160°C. This is a useful protection when the device is under sustained short circuit conditions. The AS1375 is available in an 6-pin TDFN 2x2mm package and is qualified for -40°C to +85°C operation. 2 Key Features ! Input Voltage: 2V to 5.5V ! Low Dropout Voltage: 120mV @ 200mA load !
