MC7809CT
Description
These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation.
Key Features
- Output current in excess of 1.0 ampere
- No external components required
- Internal thermal overload protection
- Internal short-circuit current limiting
- Output transistor safe-area compensation
- Output voltage offered in 2% tolerance Cin 0.33µF Co 0.1µF Notes: A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage. xx = these two digits of the part number indicate output voltage. Cin is required if regulator is located an appreciable distance from power supply filter. Co is not needed for stability, however, it does improve transient response. Mechanical Data Case: TO-220 Package Case outline is on the back page.
