RT9163 Datasheet, PDF (1/8 Pages) Richtek Technology Corporation – 500MA LOW DROPOUT POSITIVE VOLTAGE REGULATOR

RT9163
500mA Low Dropout Positive Voltage Regulator
General Description
The RT9163 is a positive low dropout regulator
designed for applications requiring low dropout
performance at full rated current. The device is
available in fixed output voltage of 3.3V, 3.5V, and
5.0V. The RT9163 provides excellent regulation over
line, load, and temperature variations.
The other features include low dropout performance
at a maximum of 1.4V at 500mA, fast transient
response, internal current limiting, and thermal
shutdown protection of the output devices. The
RT9163 is a three-terminal regulator available in
surface mount SOT-89, SOT-223, and TO-252
packages.
