RT9161/A
300/500mA Low Dropout Linear Voltage Regulator
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 most
thermal-limiting provide maximal protection against any
fault conditions.
For ease of application, the RT9161/A comes in the popular
3-pin SOT-23 (300mA), SOT-89 (300mA), SOT-223
(500mA), or TO-92 packages.
