This document describes the features and characteristics of the KF00 series products, including very low dropout voltage, very low quiescent current, output current up to 500mA, logic-controlled electronic shutdown, and a wide range of output voltage options.
The KF00 series consists of very low dropout (LDO) voltage regulators designed for low noise and low power applications, particularly suitable for battery-powered systems. These devices offer a wide range of output voltages from 1.25V to 12V with an internal current and thermal limit.
