RT9047 - Low Dropout LDO

Description

The RT9047 is a 1A linear low dropout (LDO) voltage regulator which uses an N-MOSFET pass element in a voltage follower.

The topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations.

The N-MOSFET topology also allows very low dropout.

Features

RT9047 1A, Low Voltage, Low Dropout LDO General Description The RT9047 is a 1A linear low dropout (LDO) voltage regulator which uses an N-MOSFET pass element in a voltage follower. The topology is relatively insensitive to output capacitor value and ESR, allowing a wide variety of load configurations. The N-MOSFET topology also allows very low dropout. Current consumption, when not enabled, is under 1μA and ideal for portable applications. This device is protected by thermal shutdown and foldback current limit. The RT9047 is available an SOT-223-5 package.
