DESCRIPTION
The UTC UR133/A are 300/500mA fixed output voltage low
dropout linear regulators. 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 300/500mA 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 1.5V, 1.8V, 2.2V, 2.5V, 2.7V,
2.8V, 2.9V,3.0V, 3.3V, 3.5V, 3.6V, 3.7V, 4.7V, 5.0V

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.

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℃. The
capacitance may be increased without limit.
A 1μF capacitor (or larger) should be placed between VIN to GND.
