IC REG LINEAR -18V 1A TO220ABManufacturer: onsemi
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The onsemi MC7918CT is a negative fixed voltage linear regulator IC. This component provides a stable -18V output with a maximum current capability of 1A. Designed for through-hole mounting in a TO-220-3 package, it features robust over-current and over-temperature protection. The device exhibits a typical Power Supply Rejection Ratio (PSRR) of 59dB at 120Hz and a dropout voltage of 1.3V at 1A. Its operating temperature range is from 0°C to 125°C, with a maximum input voltage of -35V. This regulator is commonly employed in power supply circuits for industrial automation, automotive systems, and consumer electronics.
