STMicroelectronics 3.3V 500mA LDO Voltage Regulator SMD SOIC8

The STMicroelectronics 3.3V 500mA LDO Voltage Regulator provides a stable and regulated +3.3V output from a variable input source. Designed for efficiency in space-constrained applications, this low-dropout (LDO) regulator offers a typical dropout voltage of just 400mV, ensuring optimal performance even as the input voltage approaches the desired output level.

Housed in a compact SOIC8 surface-mount package, it is perfectly suited for modern PCB designs. With a maximum output current of 500mA, it can reliably power a wide range of digital ICs, microcontrollers, sensors, and other low-voltage components.

Engineered for robustness, this regulator operates across an extensive temperature range from -40°C to +125°C, making it suitable for industrial, automotive, and consumer electronics applications that must endure harsh environmental conditions.
