LINEAR INTEGRATED CIRCUIT
3 TERMINAL 1A NEGATIVE
VOLTAGE REGULATOR
DESCRIPTION
The UTC 79DXXA 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 1A
*-5V, -6V, -8V, -9V,-12V, -15V, -18V, -24V output voltage available
* Thermal overload protection
