Switching regulator for 3.3V
Circuits with 3.3 volts: For small currents, a voltage regulator is sufficient. Greater efficiency can be achieved with a step-down switching regulator. This circuit proposal is loaded with good one ampere.

Linear Regulated Dual Polarity Power Supply
This document describes how to construct a dual polarity linear power supply which can be configured for any positive or negative voltage between 1.2-35V. A power supply is the fundamental building block of all...
Parallel Controlled Power Supply
Parallel-controlled circuits operate as self-controlled, variable resistors, connected in parallel to the load impedance (parallel loads). They react extremely fast and also control immediately pulses and very short mains break-downs, resulting from strong loads....

Dual Polarity Power Supply Two versions of a dual polarity power supply with printed circuit board artwork. The supplies are built around the popular LM317 & 337 complementary voltage regulators which offer very high...
Experiments with the LM2575
The standard buck regulator circuit delivers a +5V output. This is a rather straightforward circuit and will operate with a wide spread of component values. Optimal values should be selected however to get minimal...
Charger for Portable Devices
This is a simple charger you can build for devices. It can be modified for any device. This may need no modification for devices that are charged using PC USB port.
