Low voltage audio amplifier circuit from 0 9 volts

Here i share power amplifier based on IC TDA7236 . This amplifier require minimum voltage 0,9 volt and maximum voltage is 1, 6 volt , its very low voltage amplifier. You can use this amplifier everywhere just with one battery 1,5 volt. Power output 16 mW with 32 ohms impedance. see circut below :

How to Make 12 9 Volt DC to DC Converter BD139

This schema is a DC voltage output from a small DC input generate large voltage.It ‘s easy and quick to do, and reducing the value of the Z-diode, the schema can be universally adapted to other output devices of the schema voltages. The give and all diagrams represent a DC converter with 12V battery 9 volt DC input and output.

12-9 Volt DC to DC Converter Circuit Diagram

With the 10V zener diode, as in the diagram, the output voltage is approximately 9.3 volts DC. The supply voltage is used, should always be at least a few volts higher than the Zener voltage. In this example, I have a 12 Volt DC battery to provide regulated 9-volt DC output. Link

9 Volt 2 Amp PSU Single IC Regulator Power Supply

Notes

There is little to be said about this schema. All the assignment is done by the regulator. The 78S09 can bear up to 2 amps connected achievement whilst advancement a low babble and actual able-bodied adapted supply.

The ambit will assignment after the added components, but for about-face polarity aegis a 1N5400 diode is provided at the input, added cutting actuality provided by C1. The achievement date includes C2 for added filtering, if powering a argumentation ambit than a 100nF capacitor is additionally adorable to abolish any aerial abundance switching noise.
