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.
Features
Low Dropout Voltage of 200mV at Output Current
100mA, 450mV at Output Current 300mA, and
750mV at 500mA Output Current
