Description

The L7809 is a fixed output, three terminal precision positive voltage regulator in 3 pins TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single point regulation. The L78M09CV fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits maximum current the circuit will pass and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 0.5A output current.

Features:

  1. Fixed output voltage is 9V
  2. Output current is 0.5A
  3. Dropout voltage is 2V
  4. Maximum DC input voltage is 35V
  5. Output transition SOA protection
  6. Output voltage tolerance is 4%
  7. Operating temperature range 0°C to 125°C
  8. Applications: Power Management.
