People often forget that many voltage regulator ICs have an upper limit (usually 35 V) on the input voltage they can handle. That applies primarily to types with a fixed output voltage. Adjustable ...

Our energy-hungry and environmentally aware society has been slow to make good use of the sun’s “free” power. But now it’s finally taking off. Using the sun’s heat directly, for cooking and other ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication. Fig 1. This voltage regulator circuit (a) uses green ...

The 7805 voltage regulator is a great device if you want a simple way of bringing a voltage down to 5V. It’s a three-pin, one-component solution that puts out five volts and a lot of heat. Simple, not ...

Toshiba America Electronic Components (TAEC) has announced a new voltage regulator integrated circuit (IC) for automotive applications that currently achieves the world's lowest power consumption, ...

It’s often necessary to connect point-of- load (POL) dc/dc power supply modules in parallel to get a sufficiently high-current output for applications such as test instruments, blade servers, and so ...

DC-to-DC switching converters are widely used in most portable devices. They efficiently generate various regulated supply voltages for different sub-blocks within the same system board. A typical ...
