79DXXAA
LINEAR INTEGRATED CIRCUIT
3 TERMINAL 1.5A NEGATIVE
VOLTAGE REGULATOR
DESCRIPTION
The UTC 79DXXAA 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, making it essentially
indestructible.
FEATURES
* Output current up to 1.5A
*-5V, -12V output voltage available
* Thermal overload protection
