R070LD10

LINEAR INTEGRATED CIRCUIT

VOLTAGE REGULATOR

DESCRIPTION

As the UTC linear integrated LDO, the UTC R070LD10

shows a high current, high accuracy, low-dropout voltage which

built in on/off function. The features 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).

FEATURES

* Built-in ON/OFF Function

* Over Current Protection Function

* Over Heat Protection Function

* Adjustable DC Output Voltage
