TILM7805CT
Overview
The LM7805CT is a classic monolithic integrated circuit designed as a fixed-voltage positive linear regulator. It delivers a steady 5V output at currents up to 1.5A, making it a staple for local on-card regulation. The device includes internal current limiting, thermal shutdown, and safe-area protection, making it virtually indestructible under standard operating conditions.
Why Choose This Part
The TO-220 package allows for easy attachment to external heatsinks, enabling the device to handle high power dissipation. It features a high power supply rejection ratio of 80dB at 120Hz and requires minimal external components, typically only requiring input and output capacitors for stability.
Applications
Key Specifications
Getting Started
To implement the LM7805CT, connect the input pin to a DC voltage between 7V and 35V, the ground pin to common, and the output pin to your load. A 0.33uF ceramic capacitor on the input and a 0.1uF capacitor on the output are recommended to prevent oscillation and improve transient response. Ensure the tab is properly heatsinked if the voltage differential and load current result in high power dissipation.
