In this article, we focus on two key application-oriented parameters of the linear regulator: Power Supply Ripple Rejection (PSRR) and output noise. These parameters have been discussed before (see ...

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 ...

The importance of low Iq with linear regulators and LDOs. A look at low-Iq voltage supervisors in portable electronics. Battery-voltage supervisors in the IoT. In my article “What is the Essence of ...

Maxim Integrated Products has introduced a low-output-voltage linear regulator capable of delivering up to 100mA for always-on applications. The MAX16999 is designed as a parallel supply for powering ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

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 ...

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 ...

Linear Technology has announced new wider temperature range versions of its LT1763, LT3008 and LT3010 high voltage linear regulators. The new high reliability MP grade features operation from -55 to ...

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 ...
