R1MX55
LINEAR INTEGRATED CIRCUIT
VOLTAGE REGULATOR
DESCRIPTION
As the UTC linear intergrated LDO, the R1MX55 shows a
high current, high accuracy, low-dropout voltage. The feature
are: low dropout voltage, very low ground current. Cause the
series have been designed for high current loads, so they are
also used in lower current, extremely low dropout-critical systems
(in which their tiny dropout voltage and ground current values are
important attributes).
The R1MX55 is stable with ceramic capacitors. It requires a
1μF or greater capacitor for stability.
FEATURES
* Available and fixed output versions 1.5V, 1.8V, 2.5V, 3.3V, 5V
* Built-in ON/OFF function
* Over current protection function
* Over heat protection function
* Adjustable DC output voltage
