austriamicrosystems’ AS1371 is a low dropout regulator (LDO) capable of delivering up to 400 mA while operating down to a low input voltage of 1,2 V.
It operates from a 1,2 to 3,6 V supply, making it well suited for low-voltage portable battery powered applications. The device boasts low dropout voltage of 20 mV @ 100 mA, 80 mV @ 400 mA, and only 50 μA quiescent current at maximum load. The AS1371 is available with pre-programmed output voltages between 0,6 V and 3,3 V (programmable in 50 mV steps.) It also features stable output voltage with ceramic capacitors down to a value of 1 μF, strict output voltage regulation tolerances (±1%), and good line- and load-regulation. The device includes over-temperature and over-current protection, under-voltage lockout, power-OK, low battery detection and has a sense input option. A digital enabled pin allows system-level dynamic power management.
