Product Description

L7805CV Fixed Positive Voltage Regulator

5V 1.5A Linear Regulator for Stable Power Supply Circuits

The L7805CV is a three-terminal fixed positive voltage regulator, part of the widely used 78xx series [citation:2][citation:3]. It provides a stable +5V output, making it an essential component for powering microcontrollers, sensors, and various 5V logic circuits from an unregulated DC source [citation:2][citation:5][citation:7].

Wide Input Voltage Range - Accepts unregulated input from 7V to 35V for flexible power source options [citation:5][citation:11][citation:12].
Robust Protection Features internal thermal overload and shortcircuit protection, making it essentially indestructible [citation:2][citation:5][citation:7].
For reliable operation, the input voltage should be at least 7.5V to 10V to maintain regulation [citation:1][citation:3][citation:10].
This is a linear regulator. The higher the difference between input and output voltage, the more heat is generated. A heatsink is recommended when providing high current (over 1A) or operating with high input voltages.

Troubleshooting

No or incorrect output voltage:

  • Verify input voltage is at least 7V [citation:1][citation:5][citation:12].
  • Check the load current does not exceed 1.5A [citation:3][citation:7][citation:11].
  • Ensure adequate heatsinking to prevent thermal shutdown [citation:2][citation:5][citation:7].
