3 TERMINAL 0.5A NEGATIVE
VOLTAGE REGULATOR
DESCRIPTION
The UTC 79DXX series of three-terminal negative regulators
are available in TO-251 and TO-252 packages 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 0.5A
* -5V, -6V, -8V, -12V, -15V, -18V, -24V output voltage available
* Thermal overload protection
* Short circuit protection
