RT9162 Datasheet, PDF (1/6 Pages) Richtek Technology Corporation – 300MA LOW DROPOUT POSITIVE VOLTAGE REGULATOR

RT9162
300mA Low Dropout Positive Voltage Regulator
General Description
The RT9162 is a positive low dropout regulator
designed for applications requiring low dropout
performance at full rated current. The device is
available in fixed output voltages of 3.3V and 3.5V.
The RT9162 provides excellent regulation over line,
load, and temperature variations.
The other features include low dropout performance
at a maximum of 1.3V at 300mA, fast transient
response, internal current limiting, and thermal
shutdown protection of the output devices. The
RT9162 is a three-terminal regulators compatible
with industrial 78XX series and available in surface
mount SOT-89 packages.
