description
The
μ
A723 is a precision integrated-circuit
voltage regulator, featuring high ripple rejection,
excellent input and load regulation, excellent temperature stability, and low standby current. The circuit consists
of a temperature-compensated reference-voltage amplifier, an error amplifier, a 150-mA output transistor, and
an adjustable-output current limiter.
The
μ
A723 is designed for use in positive or negative power supplies as a series, shunt, switching, or floating
regulator. For output currents exceeding 150 mA, additional pass elements can be connected as shown in
Figures 4 and 5.
The
μ
A723C is characterized for operation from 0
