ON Semiconductor Fixed LDO Voltage Regulator, 3.3V/300mA, TSOP-5

The ON Semiconductor Fixed LDO Voltage Regulator is a high-efficiency, low-dropout (LDO) voltage regulator designed for stable power supply in compact, surface-mount applications. This regulator provides a fixed output of 3.3V with a maximum current of 300mA, making it an ideal choice for powering sensitive digital and analogue circuits where voltage stability is crucial.

Featuring a remarkably low dropout voltage of just 235mV (typical), it can maintain regulation even when the input voltage dips close to the output level, maximising efficiency and battery life in portable devices. With a wide input voltage range from 1.7V to 5.5V, it offers excellent versatility for systems powered by single-cell lithium-ion batteries, multiple-cell alkaline batteries, or regulated DC supplies.

Housed in a space-saving TSOP-5 surface-mount package, this regulator is perfect for modern, high-density PCB designs. Its robust construction supports an extended operating temperature range from -40°C to 85°C, ensuring reliable performance in demanding industrial, automotive, and consumer electronics environments.

The positive polarity, single-output design simplifies integration, providing a clean and stable voltage rail for microcontrollers, sensors, memory modules, and other low-power ICs. This component is a fundamental building block for creating reliable and efficient power management solutions.
