Overview
The NCP3335A, specifically the NCP3335AMN250R2G, is a high-performance, low dropout (LDO) linear voltage regulator produced by Onsemi. This device is renowned for its ultra-high accuracy of ±0.9% over line and load, along with ultra-low quiescent current and noise. It is designed to meet the stringent requirements of modern consumer electronics, ensuring stability without a minimum load current requirement and compatibility with any type of capacitor as small as 1.0 µF. The regulator also features sense and noise reduction pins, and it offers reverse bias protection for enhanced reliability.
