LINEAR INTEGRATED CIRCUIT
3 TERMINAL 0.5A NEGATIVE VOLTAGE
REGULATOR
DESCRIPTION
The UTC 79DXX series of three-terminal negative
regulators are available in TO-252 and TO-251 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.
