Precision voltage regulator
Product specification
µA723/723C
DESCRIPTION
The µA723/µA723C 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.
FEATURES
Positive or negative supply operation
Series, shunt, switching, or floating operation
0.01% line and load regulation
Output voltage adjustable from 2V to 37V
Output current to 150mA without external pass transistor
µA723 MIL-STD-883A, B, C available
