STMicroelectronics 5V 800mA LDO Voltage Regulator SOT-223-3

The STMicroelectronics 5V 800mA LDO Voltage Regulator is a high-performance integrated circuit designed to deliver a stable, fixed 5V output from a variable input voltage ranging from 6.5V to 15V. It features a low dropout (LDO) architecture with a typical dropout voltage of just 1.1V, ensuring efficient regulation even when the input voltage is close to the output level. This makes it exceptionally suitable for battery-powered applications where maximising operational life is critical.

With a robust maximum output current of 800mA, this regulator can power a wide array of components and subsystems. Its positive output polarity and single-output design simplify circuit integration. The device is presented in a compact, surface-mount SOT-223-3 package, ideal for modern, space-constrained PCB designs. It operates reliably across an extensive temperature range from -40°C to 125°C, guaranteeing performance in harsh environmental conditions.
