400mA low input voltage, ultra low dropout regulator
Austriamicrosystems, a global designer and manufacturer of high performance analogue ICs for communications, industrial, medical and automotive applications, has expanded its ultra low dropout regulator (LDO) range with the AS1371.
The device is capable of delivering up to 400mA while operating down to a low input voltage of 1.2V. The AS1371 operates from a 1.2 to 3.6V supply, making it suitable for low voltage, portable battery powered applications.
Offering low dropout voltage of 20mV at 100mA, 80mV at 400mA, and with 50µA quiescent current at maximum load, the AS1371 is designed to maximise battery life and performance.
It is available with pre-programmed output voltages between 0.6 and 3.3V (programmable in 50mV steps) and features stable output voltage with ceramic capacitors down to a value of 1µF, strict output voltage regulation tolerances (±1%), and line and load regulation.
The device includes integrated overtemperature/ overcurrent protection, under voltage lockout, power-okay, low battery detection and has a sense input option. A digital enabled pin allows system level dynamic power management.
The AS1371 is available in a 6pin 2 by 2 TDFN package and is qualified for -40 to 85°C operation.
