UTC UR132 LINEAR INTEGRATED CIRCUIT

200mA LOW DROPOUT LINEAR
VOLTAGE REGULATOR

DESCRIPTION

The UTC UR132 is a 200mA fixed output voltage
low dropout linear regulator. Wide range of available
output voltage fits most of applications. Built-in output
current-limiting most thermal-limiting provide maximal
protection against any fault conditions.

FEATURES

*Guaranteed 200mA output current
*Input voltage range up to 12V
*Extremely tight load regulation
*Fast transient response
*Current-limiting and Thermal-limiting
*Three-terminal adjustable or fixed voltage.

APPLICATIONS

*Voltage regulator for LAN Card, CD-ROM, and DVD
*Wireless communication systems

Note 1: Guaranteed by design.
Note 2: Regulation is measured at constant junction temperature, using pulsed ON time.
Note 3: Current Limit is measured at constant junction temperature, using pulsed ON time.
Note 4: Dropout is measured at constant junction temperature, using pulsed ON time, and the criterion is V

inside target value±2%.

Note 5: Dropout test is skipped at the condition of V
