STMICROELECTRONICS KF25BDTR Low Drop Voltage Regulator

The STMICROELECTRONICS KF25BD-TR is a very low drop voltage regulator designed for low noise, low power applications, and battery-powered systems. It offers a very low dropout voltage (0.4 V) and a very low quiescent current, making it ideal for applications where power efficiency is critical. The regulator features logic-controlled electronic shutdown and requires only a 2.2 µF capacitor for stability. It is available in SO-8 and DPAK packages and offers a wide range of output voltages, making it versatile for various industrial applications.
