STMICROELECTRONICS KF33BDTR Low Drop Voltage Regulator

The STMICROELECTRONICS KF33BD-TR is a very low drop voltage regulator designed for low noise, low power applications, particularly in battery-powered systems. It boasts a very low dropout voltage (0.4V) and a low quiescent current, making it efficient and suitable for a wide range of applications. The regulator includes logic-controlled electronic shutdown and requires only a 2.2 µF capacitor for stability, saving space and cost. It is available in SO-8 and DPAK packages with various output voltages.
