R200LD10
LINEAR INTEGRATED CIRCUIT
VOLTAGE REGULATOR
DESCRIPTION
The UTC R200LD10 shows a high current, high accuracy,
low-dropout voltage. 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,
* ASO protection function
* Overheat protection function
* 0.3A / 3.3V(R1=2KΩ)
Output low dropout voltage regulator
