Overview

The LP2950ACZ-5.0/NOPB is a high-accuracy, micropower linear voltage regulator that provides a fixed 5V output. It is characterized by its exceptionally low quiescent current of 75uA and a low dropout voltage of 0.6V at its full 100mA load. This device is particularly suited for battery-powered systems where minimizing power waste is critical for longevity.

Why Choose This Part

The LP2950ACZ-5.0/NOPB offers a very low temperature coefficient and tight line and load regulation, ensuring stable performance across varying conditions. Its internal current and thermal limiting provide robust protection against faults, and it remains stable even when using low-ESR output capacitors.

Applications

Battery-Powered Instrumentation
Ideal for hand-held meters and portable data loggers due to the 75uA low standby current.
Post-Regulator for Switching Supplies
Used to provide a clean, low-noise 5V rail from the output of a high-efficiency switching converter.
Automotive Electronics
Operates across a wide temperature range of -40C to 125C for non-safety critical cabin electronics.
Embedded System Power
Provides a stable 5V supply for microcontrollers and sensors with tight 0.5 percent output accuracy.

Getting Started

To implement this regulator, place a 1uF or larger capacitor on the output to ensure stability; for many applications, a 2.2uF tantalum capacitor is recommended. Ensure the input voltage remains below the 30V maximum limit and account for the TO-92 package's thermal resistance when operating at high input-to-output voltage differentials.
