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.

The part may oscillate without the capacitor, a 10μF (or larger) capacitor is recommended between V

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 V
