Product Description
onsemi NCP1117LPST50T3G is a fixed low dropout (LDO) linear voltage regulator delivering output current above 1A with positive polarity in a small SOT-223 4-Pin surface mount package.
This voltage regulator operates with a maximum input voltage of 18V and supports a dropout voltage as low as 1.2V at 800mA, optimized for efficient power management in electronic circuits.
The device features a quiescent current of only 700μA which allows for reduced power consumption and improved battery life in portable applications. Equipped with internal current limit and thermal shutdown protection circuits, the NCP1117LPST50T3G ensures reliability and safe operation even under fault conditions.
Automotive-grade qualification according to AEC-Q100 standard makes it suitable for automotive and industrial applications requiring high reliability and temperature range up to 125°C.
Package dimensions of 6.7mm length, 3.7mm width, and 1.69mm height facilitate compact PCB design within consumer electronics, industrial equipment, and power management systems. Supports fixed and adjustable voltage output settings programmable between 1.25V and 18.8V.
Widely used for active SCSI termination, switching power supply post regulation, hard drive controllers, and battery charging circuits. Ensures low noise and high power supply rejection ratio (PSRR) for sensitive analog and digital systems.
Suitable for diverse industrial, automotive, and consumer electronics applications requiring efficient voltage regulation and protection. Explore additional onsemi power management ICs and Voltage Regulators on EnvMart for optimized electronic designs.
