Overview

The L7805ABD2T-TR is a three-terminal positive linear voltage regulator that delivers a fixed 5.0V output. This robust component supports an output current of up to 1.5A and includes internal current limiting, thermal shutdown, and safe area protection, making it essentially indestructible in many applications. It is housed in a D2PAK surface-mount package, providing better thermal performance than standard through-hole variants in high-power scenarios.

Why Choose This Part

This regulator offers high output current capability and integrated protection circuitry that prevents damage from overheating or short circuits. The 2 percent output voltage tolerance ensures precision for sensitive digital circuits without requiring external adjustment components.

Applications

Local On-Card Regulation
Eliminates distribution problems associated with single point regulation by providing stable power directly at the load.
Power Supplies for TTL Logic
Provides a clean and precise 5.0V rail necessary for standard digital logic families and legacy microcontrollers.
Battery Charger Circuits
Used as a current-limited constant voltage source for charging small battery packs or maintaining standby power.
Industrial Control Systems
Regulates noisy industrial DC rails down to a stable voltage for sensors and small control interface circuits.

Getting Started

When designing with this regulator, place a 0.33uF ceramic capacitor on the input and a 0.1uF capacitor on the output as close to the device pins as possible to ensure stability. Use adequate PCB copper pours around the D2PAK tab to manage thermal dissipation, as the device will drop excess voltage as heat.
