General Description
The RT9161/A is a 300/500mA fixed output voltage
low dropout linear regulator. Typical ground current
is approximately 110µA, from zero to maximum
loading conditions. Wide range of available output
voltage fits most of applications. Built-in output
current-limiting
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.
