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.

Note: 1. Guaranteed by design.
2. Regulation is measured at constant junction temperature, using pulsed on time.
3. Current limit is measured at constant junction temperature, using pulsed on time.
4. Dropout is measured at constant junction temperature, using pulsed on time, and the criterion is VOUT inside
target value±2%.
5. Dropout test is skipped at the condition of VIN<3V.

LINEAR INTEGRATED CIRCUIT
TYPICAL APPLICATION CIRCUIT
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.
