1. Microcomputer power supply and reset circuit
2. Output current boost circuit
Application Circuits
To construct a microcomputer power supply and a reset circuit using conventional ICs, a voltage regulator
IC, a voltage detector IC, a delay time generation circuit and others are required. The A/B type allows
you to make these circuits without these ICs, and the delay time is variable.
Caution The above connection diagram and constants do not guarantee correct operation.
A PNP transistor is used to increase the output current.
