HA17723/F/P
Precision Voltage Regulator
Description
The HA17723 high-accuracy general-purpose voltage regulator features a very low stand-by current,
(quiescent current) a low temperature drift, and high ripple rejection ratio. If you need over than 150mA
output current, adding external PNP or NPN transistor. This voltage regulator is suitable for various
applications, for example, series or parallel regulator, switching regulator.

Switching Regulator
Figure 7 shows a switching regulator circuit. The error amplifier, control circuit, and forward feedback
circuit R4 and R3 operate in together as a comparator, and make the external transistors Q1 and Q2 to turn
on/off. In this circuit, the self-oscillation stabilizes the output voltage and the change in output is absorbed
by the changes of the switches conducting period.
Figures 8 and 9 show a negative voltage switching regulator circuit and its characteristics.
