AS1370 High Voltage, Low Quiescent Current, 200mA LDO The AS1370 low-power, positive voltage regulator is designed General Description to deliver up to 200mA, while consuming only 3A of quiescent current. The device is available in fixed output voltages between 1.2V and 5.5V (programmable in 100mV steps). Standard options of 1.2, 1.8, 2.5, 3.0, 3.3, 4.5, 5.0 and 5.5V are also available. The input voltage ranges from 2.6V to a maximum of 50V. 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 (550mV 200mA load) prolongs battery life and allows high current in small applications with minimum input-to-output voltage differentials. The device features very stable output voltage (using only 1F ceramic capacitor), and excellent line- and load-regulation. The AS1370 also features a Power-OK Output. The device features integrated short-circuit and over current protection. Thermal Protection shuts down the device when die temperature reaches 170C. This is a useful protection when the device is under sustained short circuit conditions. The AS1370 is available in an 8-Pin MLPD 3mm x 3mm package and is qualified for -40C to 125C operation.
