3 TERMINAL 1A NEGATIVE
VOLTAGE REGULATOR

DESCRIPTION
The UTC 79TXXA series of three-terminal negative
regulators are available in TO-263 package and with 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.
FEATURES
*Output current up to 1A
*-5V, -6V, -8V, -9V, -12V, -15V, -18V, -24V output voltage
available
*Thermal overload protection
*Short circuit protection
