austriamicrosystems has expanded its low dropout regulator portfolio with the dual LDO AS1374, capable of delivering up to 200 mA continuous load current at each output.
austriamicrosystems' AS1374 operates from a 2 to 5.5 V supply, making it ideal for portable battery powered applications. Offering low 120 mV dropout at 200mA load currents at each output, it has been designed and optimized to work with low-cost, small-capacitance ceramic capacitors. The AS1374 is available with preprogrammed output voltages between 1.2 V and 3.6 V (programmable in 50mV steps). The device uses an advanced architecture to achieve ultra low output voltage noise of 20 uVRMS and a power supply rejection ratio of better than 85 dB (@ 1kHz). Two active-high enable pins allow the possibility to switch on or off each output independently from each other.
The AS1374 requires only 1 uF output capacitor for stability at any load. The device is available in a 6-bump WLP package.
