This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

When designing low-power USBcircuits that require power-supplyvoltages other than 5V, you must decidewhether to use a separate battery or aphysically small mains-based powersource. The problem is ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices. Their ...

Makers, developers and hobbyists looking for a dual output USB step up breadboard power supply might be interested in a new device which has been created by Bradley Slattery called the Toaster. The ...

Called TSV782 and working down to 2V, allowing it to use the same power rail as low-voltage logic devices, and consumption is 3.3mA/channel – there is no shut-down pin to reduce this. Slew rate is 20V ...

Two new CMOS dual input low dropout (LDO) voltage regulators from National Semiconductor offer the industry’s lowest dropout. Optimized for low-voltage, Two new CMOS dual input low dropout (LDO) ...
