UNISONIC TECHNOLOGIES CO., LTD
79DXXA
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, -7V, -8V, -9V,-12V, -15V, -18V, -24V output voltage
available
* Thermal overload protection
