Many low-dropout voltage regulators include an enable-input pin that can also serve as an inexpensive alternative to a voltage-supervisor IC. Although the enable pin normally serves as a means of ...

In Figure 1, the 5V linear regulator (U1) delivers as much as 150mA of load current when operating by itself. Operating with the external pass transistor shown (Q1), the circuit maintains 5V ...

Linear Technology introduces the LTM8020, the first in a new family of DC/DC uModule regulator systems that operate from higher voltage input supplies of up to 36V (40Vmax). The LTM8020 is a 200mA ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

LDOs can offer the low noise and PSRR performance to be used in wide voltage range applications such as in test and measurement systems, write Amit Patel and Steve Knoth Linear Regulators are ...

For thirty-seven years after introduction of the first three-terminal adjustable linear regulators, this topology has seen virtually no major architectural changes. These older generation linear ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

QUESTION: There are so many different voltage regulators on the market these days. How do I pick one that will be good for my circuit? ANSWER: Wow, this is a tough question, but also a good one. I’ll ...
