3_A_LOW_ROPOUT_REGULATOR_WITH_50_μA_QUIESCENT_CURRENT

Published:2009/7/16 20:51:00 Author:Jessie | From:SeekIC

The LT1529 is a 3-A, 0.6-V dropout regulator with 50-μA no-load quiescent current and only 16 μA IQ shutdown. This makes the LT1529 useful for battery-powered applications where both long battery life and high-load current surges are expected. At 1.5-A load current, dropout voltage is just 0.43 V. The LT1529 needs no external diodes to protect against reverse battery or reverse output current faults. This allows the LT1529 to be used for backup power situations in which the output is held high while the input is at ground or reversed.
