KF33BDT-TR ST LDO Voltage Regulator | DPAK | 3.3V Output, 1A Current

Product Overview

The KF33BDT-TR from STMicroelectronics is a low-dropout (LDO) voltage regulator designed to deliver a fixed output voltage of 3.3V with a maximum output current of 1A. Housed in a DPAK (TO-252) surface-mount package, this device offers excellent line and load regulation, making it suitable for a wide range of applications requiring a stable and efficient power supply. The KF33BDT-TR features a dropout voltage as low as 0.4V at 1A output, enabling operation with minimal input-to-output voltage differential. It includes internal protection circuits such as current limiting and thermal shutdown, ensuring reliable performance under fault conditions.
