General Description

The RT9161/A is a 300/500mA fixed output voltage low dropout linear regulator. Typical ground current is approximately 110?A, from zero to maximum loading conditions. Wide range of available output voltage fits most of applications. Built-in output current-limiting most thermal-limiting provide maximal protection against any fault conditions.

For ease of application, the RT9161/A comes in the popular 3-pin SOT-89 (300mA), SOT-223 (500mA), or TO-92 packages.
