High-Current Low-Dropout Adjustable Regulator

Description

lThe MIC29302WUis ahigh current, highaccuracyand low-dropout voltage regulator.Thisregulator features300mV to 370mV (full load)dropout voltage and very low ground current. Designed forhigh current load, thedevice also finds applications inlower current, extremely low dropout-critical systems, where its tiny dropout voltage and ground current value areimportant attributes.

lThe MIC29302WUisfully protected againstover-current fault, reversed input polarity, reversed leadinsertion, over-temperature operation, and positive and negativetransient voltage spikes.

lOn the MIC29302WU, the ENABLE pin may betied to VINif it is not required for ON/OFF control.

lTheMIC29302WUisavailable in TO263-5L package.
