Low Power Bipolar Stabilizer

Bipolar Power Supply schematicThe stabilizer is made ​​on the integrated circuit KR142EN6. IC is a bipolar voltage regulator with an output voltage of + / -15 V. Maximum load current is 200 mA. Enough to supply a pre-amplifier or the early stages of the power amplifier.
Diode bridge – any of a series of KTS407, KTS405, KTS402.
Transformer with two secondary windings, the voltage on each – 16 Volt.

Parts list :
C1, C2 : 1000uF/25V
C4, C5 : 1000
C3, C6 : 33uF/25V
D1 : KTS407, KTS405, KTS402
IC1 : KR142EN6

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
