Texas Instruments uA723CD
The µA723 is a precision integrated-circuit VCC– 7 8 NC 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.µA723 PRECISION VOLTAGE REGULATORS SLVS057D – AUGUST 1972 – REVISED JULY 1999 D 150-mA Load Current Without External Power Transistor D OR N PACKAGE (TOP VIEW) D Adjustable Current-Limiting Capability D Input Voltages up to 40 V D Output Adjustable From 2 V to 37 V D Direct Replacement for Fairchild µA723C NC 1 CURR LIM 2 CURR SENS 3 IN– 4 14 NC 13 FREQ COMP 12 VCC+ 11 VC IN+ 5 10 OUTPUT description REF 6 9 VZ The µA723 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.
