This circuit is a depressing power supply integrated. Which can be situated useful to circuits with the intention of carry out not need much course. Using IC rejection. 555. The primary of the circuit.
|IC555 Negative supply voltage low current schematic|
Exertion of the circuit is IC1, R1, R2 and C1. The range of the A lasting Multi Vibrator, and the output is a open place wave. It is a upbeat hint pulse frequency of 2.3 kHz output pin 3 of IC1.And C3 and D1 connected to circuit CLAMP. to it serves to signal a positive pulse to pulse signal unenthusiastic.The D2 and C3 play-act negative pulse warning sign is converted order current (DCV) electrical signals. The negative power. in this fashion the output voltage to a negative DC electrical.
