DESCRIPTION
2
The UTC UR132 is a 200mA fixed output voltage low dropout
SOT-23
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.

The part may oscillate without the capacitor, a 10µF (or larger) capacitor is recommended between VOUT and GND
for stability. Any type of capacitor can be used, but not Aluminum electrolytic when operating below -20°C. The
capacitance may be increased without limit. Besides, another 1µF capacitor (or larger) should be placed between VIN
to GND.
