UR133 - Low Dropout Linear Voltage Regulator

Download the UR133 datasheet PDF. This datasheet also covers the UR133A variant, as both devices belong to the same low dropout linear voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • S 1 SOT-89 1 TO-92.
  • 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.
