Product Overview

The NCP1117 and NCV1117 series of LDO positive fixed and adjustable voltage regulators have an output current in excess of 1A. Available in either SOT-223 or DPAK packages, they also come in a range of different output voltage options, fixed or adjustable. The fixed voltages have no minimum load requirement to maintain regulation. There is also adjustable output voltage options which can be programmed from 1.25 to 18.8 V.
In comparison to other three-terminal adjustable regulators, the NCP1117 devices feature a large reduction in dropout voltage with improved output voltage accuracy and temperature stability.
The NCP1117ST50T3G series are low dropout positive voltage regulators that are capable of providing an output current that is in excess of 1 A with a maximum dropout voltage of 1.2V at 800mA over temperature. On chip trimming adjusts the reference/output voltage to within ±1.0% accuracy.

FAQ

1. What is NCP1117ST50T3G?
The NCP1117ST50T3G is a low dropout positive voltage regulator manufactured by ON Semiconductor. The NCP1117ST50T3G is capable of providing an output current in excess of 1.0A whereas the maximum dropout voltage is 1.2V. The output voltage is 5V stable DC. The salient features of this device include safe operating area compensation, thermal shutdown, and output current limiter. The device package is Lead free SOT-223.  

 

2. How NCP1117ST50T3G work?
The NCP1117ST50T3G is a low-drop positive voltage regulator which is widely used in switching power supply circuits to get fixed and stable 5V output. One of the most common NCP1117ST50T3G based circuit is the full wave diode rectifier power supply. In this power supply, the first stage is a power transformer which steps down 220/120VAC to 5VAC. The 2nd circuit stage is the diode rectifier which converts the 5VAC to 5VDC. The 3rd stage in the circuit is the LD1117 regulator which removes the ripple from the converted DC voltage and provides a stable DC voltage at the output.

 

3. What is the package of NCP1117ST50T3G Regulator?

SOT-223 3-pin + tab package.

 

4. What are advantages of NCP1117 devices?

The NCP1117 devices feature a large reduction in dropout voltage with improved output voltage accuracy and temperature stability.
