Dual ultra low voltage noise LDO delivers 200 mA continuous load current at each output

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.
