NCP1117DT18G Description

Short technical summary and product information.

The NCP1117DT18G is a linear voltage regulator from On Semiconductor that provides a fixed output voltage of 1.8V with a maximum output current of 1A. The device operates with a maximum input voltage of 20V and features a typical quiescent current of 10mA. It offers a power supply rejection ratio (PSRR) of 70dB at 120Hz and an output voltage accuracy of ±1%. The maximum dropout voltage is 1.2V at 800mA load, with a typical value of 1.07V.

 

The regulator includes over current and over temperature protection, ensuring reliable operation in a variety of applications. It is designed for surface mount assembly and is available in a TO-252-3 / DPAK package (also known as SC-63). The operating temperature range is 0°C to 125°C.

 

This regulator is suitable for systems requiring a stable 1.8V supply with low dropout, such as power management for microcontrollers, embedded systems, and portable electronics. The fixed output simplifies design and reduces external component count.
