[limpkin] writes us to show a line injector they’ve designed. The principle is simple — if you want to measure how much PSU noise any of your electronic devices let through, known as PSRR (Power ...

Ensuring stable power management is crucial in modern electronics, and the power supply rejection ratio (PSRR) plays a key role in achieving this. This article serves as a practical guide to measuring ...

Now that we've summarized the many noise doorways of an ADC (see, for example, ADC Noise: A Second Look, Part 2), let's start focusing in on each one. First, we'll take a look at noise that enters the ...

A power supply rejection ratio test set-up can be configured with key components, explains Andreas Ibl and Marcus Sonst. The power supply rejection ratio (PSRR) indicates the stability of a power ...

Earlier this month Power Electronics received a question about "How to measure PSRR of a linear regulator circuit that powers an oscillator for an ADC. How can I make this measurement using my ...

Intersil’s new family of high-performance dual LDOs (low dropout regulators) provide a high PSRR (power supply rejection ratio), low quiescent current (I Q), and excellent noise performance for RF and ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

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 ...

Current fold-back is included, to 60mA for low-current mode and 110mA for high-current mode, to alleviates thermal shut-down cycling during short-circuit fault conditions, and to helps protect the IC ...

The LT3042 is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive RF applications. Designed as a precision ...
