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 ...

This article presents linear regulators and the computation of its efficiency. It also describes the advantages and other properties of a linear regulator, as well as the low drop out (LDO) regulator, ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are unconditionally stable. The answer is both simple and complex, if it is ...

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 ...

Low dropout linear regulators are useful where a low-noise power source is needed, and where the regulator must maintain regulation with small differences between the input supply voltage and output ...

For 0.13um to 0.35um Logic/Mixed-Signal, and 0.18um & 0.35um EEPROM CMOS process technologies Shanghai, CHINA, December 21, 2005 -- Semiconductor Manufacturing International Corporation (“SMIC†, ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

Linear Technology has unveiled the LT3045, an ultra-low noise, ultra-high power supply ripple rejection (PSRR) low dropout voltage linear regulator. The device is a higher output current version of ...
