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.

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 VOUT
inside target value±2%.
Note 5: Dropout test is skipped at the condition of VIN<3V.

UR132
APPLICATION INFORMATION
A 10µF (or larger) capacitor is recommended between VOUT and GND for stability. The part may oscillate
without the capacitor. Any type of capacitor can be used, but not Aluminum electrolytics when operating below -25°C.
The capacitance may be increased without limit.
A 1µF capacitor (or larger) should be placed between VIN to GND.
