Product Description

onsemi NCP1117ST50T3G is a fixed output low dropout (LDO) linear voltage regulator providing a precise 5V output with a maximum input voltage rating of 20V. Housed in a compact SOT-223 4-pin surface mount package, this regulator supports output currents in excess of 1A, suitable for demanding electronic circuits.

This device features an ultra-low dropout voltage of 1.2V at 800mA load, making it highly efficient in power management applications with minimal voltage loss between input and output. It incorporates robust current limiting and thermal shutdown capabilities, enhancing circuit protection under abnormal conditions.

NCP1117ST50T3G is AEC-Q100 qualified, confirming its reliability for automotive electronics, and supports operation up to 125°C maximum temperature. It requires no minimum load to maintain regulation, simplifying design across various load conditions.

The regulator’s dimensions (length 6.7mm, width 3.7mm, height 1.69mm) enable compact PCB layouts. It is a positive polarity device ideal for replacing linear regulators in consumer electronics, industrial equipment, battery chargers, power supplies, and hard drive controllers.

Applications include consumer and industrial equipment powering, active SCSI termination at 2.85V version, and switching power supply output post regulation for stable voltage delivery.
