IC REG LINEAR 1.8V 1A SOT223Manufacturer: onsemi
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The onsemi NCP1117ST18T3 is a positive fixed voltage linear regulator IC. This component provides a stable 1.8V output with a maximum current capability of 1A. Designed for surface mounting within a SOT-223 (TO-261-4, TO-261AA) package, it operates within an ambient temperature range of 0°C to 125°C. Key protection features include over-current and over-temperature shutdown. The regulator exhibits a typical quiescent current of 10 mA and a power supply rejection ratio (PSRR) of 70dB at 120Hz. With a maximum input voltage of 20V, the voltage dropout is specified at 1.2V when delivering 800mA. This device is commonly utilized in industrial and consumer electronics applications requiring reliable voltage regulation.
