IC REG LINEAR -9V 1A TO220-3Manufacturer: onsemi
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The onsemi LM7909CT is a fixed, negative linear voltage regulator IC. This component provides a stable -9V output with a maximum output current of 1A. Designed with through-hole mounting in a TO-220-3 package, it offers integrated protection against over-temperature and short circuits. The device features a typical quiescent current of 6mA and a power supply rejection ratio (PSRR) of 60dB at 120Hz. Input voltage can be as high as -35V, with a typical dropout voltage of 2V at 1A. This regulator is suitable for applications in telecommunications, industrial control, and consumer electronics requiring reliable negative voltage regulation.
