300/500mA LOW DROPOUT
LINEAR VOLTAGE REGULATOR
DESCRIPTION
The UTC UR133/A is a 300/500mA 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 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 , 3.7V ,
4.7V , 5.0V
APPLICATIONS
*Voltage regulator for LAN Card, CD-ROM, and DVD
*Wireless communication systems
