Negative supply voltage low current

This circuit is a negative power supply integrated. Which can be applied to circuits that do not need much flow. Using IC No. 555. The core of the circuit.
Work of the circuit is IC1, R1, R2 and C1. The range of the A Stable Multi Vibrator, and the output is a square wave. It is a positive signal pulse frequency of 2.3 kHz output pin 3 of IC1.And C3 and D1 connected to circuit CLAMP. That it serves to signal a positive pulse to pulse signal negative.The D2 and C3 act negative pulse signal is converted direct current (DCV) electrical signals. The negative power. Thus the output voltage to a negative DC electrical.

Negative Volage Regulator 6V not use Transformer

If friends with look for Mini power supply 6V sizes. That give negative voltage. I begs for to advise this circuit. It has prominent small-sized point and light weight. Because do not use Transformer. But still can use current get 0.07Amp not exceed and when see the circuit. Think use Zener diode control voltage be stable that 6V and have transistor enlarge the trend equal to that want. And still systematically protect through the circuit or Shot Circuit Protect with Transistor as well. The detail is other , see in circuit picture has yes.

9V Negative power supply units

Today I seeks Negative power supply units Circuit 9Volt sizes give friends. See in rows think ? circuit character resemble with positive voltage supply the other only get back to the direction of the electricity only. When use Transistor 2SC1061 or TIP31 as a result give current about 1A and Transformer must have 1Amp size with. Request have fun 9V Negative power supply units please sir.
