Precision voltage regulator
碌A(chǔ)723/723C
DESCRIPTION
The
碌A(chǔ)723/碌A(chǔ)723C
is a monolithic precision voltage regulator
capable of operation in positive or negative supplies as a series,
shunt, switching, or floating regulator. The 723 contains a
temperature-compensated reference amplifier, error amplifier, series
pass transistor, and current limiter, with access to remote shutdown.
