RT9165
150mA 3-Terminal Positive Regulator
General Description
The RT9165 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 5.0V or 8.0V. The
RT9165 provides excellent regulation over line, load,
and temperature variations.
The other features include low dropout performance
at a maximum of 1.3V at 150mA, fast transient
response, internal current limiting, and thermal
shutdown protection of the output devices. The
RT9165 is a three-terminal regulator compatible with
industrial LM78L05/L08 and available in surface
mount SOT-89 package.

(1) Low duty cycle pulse testing with Kelvin connections required.
(2) Dropout voltage is defined as the input to output differential at which the output voltage drops 1% below the
value measured with a 2V differential.
(3) Bandwidth of 10 Hz to 10 kHz.
