The KA7809ETU from On Semiconductor is a positive voltage regulator IC designed for a wide range of applications. It provides a stable 9V output voltage with a maximum output current of 1A. The device accepts an input voltage up to 35V and features built-in over-temperature and short-circuit protection.
With a dropout voltage of 2V at 1A and a quiescent current of 8mA, the KA7809ETU is suitable for various power management tasks. It operates within a temperature range of 0°C to 125°C and has a Power Supply Rejection Ratio (PSRR) of 71dB at 120Hz.
The regulator is supplied in a TO-220-3 package, designed for through-hole mounting. This package type facilitates easy integration into circuit boards for applications requiring reliable voltage regulation. The component is RoHS compliant and has a Moisture Sensitivity Level (MSL) of 1.
Key electrical characteristics include a nominal 9V output, 1A maximum output current, and 35V maximum input voltage. The fixed output type and positive output configuration make it a straightforward solution for many electronic designs.
