STMicroelectronics Fixed LDO Voltage Regulator 5V 500mA TO-252-3

The STMicroelectronics Fixed LDO Voltage Regulator delivers a stable 5V output with a very low dropout voltage of just 450mV, making it ideal for battery-powered and low-power applications. This surface-mount device is housed in a compact TO-252-3 (DPAK) package and provides up to 500mA of output current, ensuring reliable performance in space-constrained designs.

Engineered for efficiency, this regulator features a very low quiescent current of 50µA in OFF mode and 500µA in ON mode, helping to extend battery life. The logic-controlled electronic shutdown function allows for power management, while the internal current and thermal limits protect the device and your circuit. With automotive grade AEC-Q100 qualification, it is suitable for demanding environments.
