Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KF15BDT-TR

KF15BDT-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The KF15BDT-TR is a very low dropout linear voltage regulator manufactured by STMicroelectronics, providing a fixed 1.5 V output with a maximum current of 500 mA. It operates within an input voltage range of 2.5 V to 20 V and features a typical dropout voltage of 0.4 V at full load. The device incorporates internal current limiting and thermal shutdown protection. It requires only a 2.2 µF output capacitor for stability and includes a logic-controlled electronic shutdown function compatible with TTL levels.
