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
