LINEAR INTEGRATED CIRCUIT

3 TERMINAL 1.5A NEGATIVE

VOLTAGE REGULATOR



DESCRIPTION

TO-220

The UTC LM79XXA series of three-terminal negative

regulators is available several fixed output voltage, making them

useful in a wide range of application. Each type employs internal

current limiting, thermal shut-down and safe area protection,

making it essentially indestructible.
