KF25BD-TR Datasheet | STMicroelectronics

KFXX Very low drop voltage regulators with inhibit SO-8 DPAK Features - Very low dropout voltage (0.4 V) - Very low quiescent current (typ. 50 µA in OFF mode, 500 µA in ON mode) - Output current up to 500 mA - Logic-controlled electronic shutdown - Output voltages of 2.5; 3.3; 5; 8 V - Internal current and thermal limit - Only 2.2 µF for stability - Available in ± 2 % accuracy at 25 °C - Supply voltage rejection: 70 db (typ.) - Temperature range: - 40 to 125 °C Datasheet - production data Description The KF series are very low drop regulators available in SO-8 and DPAK packages and in a wide range of output voltages. The very low dropout voltage (0.4 V) and the very low quiescent current make them particularly suitable for low noise, low power applications and especially in battery powered systems. A shutdown logic control function is available (pin 5, TTL patible). This means that when the device is used as a local regulator, it is possible to put a...
