Microchip Fixed LDO Voltage Regulator 3.3V 500mA SOT-23-5

The Microchip Fixed LDO Voltage Regulator offers an efficient and reliable power management solution in a compact 5-pin SOT-23 package. Designed with high peak output current capability, this device provides better than 1% output voltage accuracy, ensuring stable and precise performance for your electronic circuits.

A standout feature of this regulator is its very low dropout voltage of 350mV at 500mA, making it highly suitable for battery-powered applications where minimising power loss is critical. When disabled via a CMOS or TTL compatible signal, power consumption drops nearly to zero, further prolonging battery life. Additionally, the device incorporates overtemperature shutdown, current and thermal limiting, and reversed battery protection to safeguard your system.

With its ultra low noise output and extremely tight load and line regulation, this LDO voltage regulator delivers clean and consistent power. It operates within a supply input voltage range from 2.5V to 12V and features a fixed output voltage of 3.3V with a peak output current capability of 500mA. The junction temperature range spans from -40°C to 125°C, ensuring robust operation in demanding environments.
