LINEAR INTEGRATED CIRCUIT
3-TERMINAL ADJUSTABLE
REGULATOR
DESCRIPTION
The UTC UM5237 is a 3-terminal adjustable regulator. It’s
used as a variable output voltage regulator.
The UTC UM5237 has a less power dissipation and more
exact loading voltage regulation .it‘s suitable for driver circuit,
differential amplifier and reference voltage generator circuit, etc.
FEATURES
* Wide Input/Output voltage range
* Low Dropout Voltage
* Over current protect
* External circuit can adjust the output voltage
