Microchip 3V 300mA LDO Voltage Regulator SOT-23-5

The Microchip 3V 300mA LDO Voltage Regulator is a high-performance, fixed-output voltage regulator designed for stable power delivery in compact electronic applications. Its low dropout voltage of just 160mV makes it highly efficient, allowing it to maintain a regulated 3V output even when the input voltage is only slightly higher, which is ideal for battery-powered devices where maximising runtime is critical.

This surface-mount device (SMD) comes in a space-saving SOT-23-5 package, making it perfectly suited for modern, miniaturised PCB designs. It features a single positive output capable of delivering up to 300mA of continuous current, providing reliable power to microcontrollers, sensors, and other low-voltage components.
