3-TERMINAL REGULATOR (-3.3V)
SC1714
February 2, 1998
Note:
(1) Add suffix ‘TR’ for tape and reel.
FEATURES
• Low power supply current.
• Low negative TC.
• High output sinking capability.
• Ouput overload protection.
DESCRIPTION
The SC1714 is a 3-terminal negative voltage regulator
with an output voltage rated at 3.3V below the positive
supply voltage. Designed to be an improved plug in
replacement for the BA714, it offers a low typical
supply current of 12µA, a high output current sinking
capability of 5mA, and a low negative temperature
coefficient. It also features output overload protection.
The SC1714 is ideal as a power source for liquid
crystal displays.
