Overview

The L78L05ACZ-AP is a fixed 5V positive linear voltage regulator capable of delivering up to 100mA of output current. It is housed in a TO-92 package with formed leads, making it ideal for low-power regulation in through-hole designs. This IC includes internal thermal overload protection and short-circuit current limiting to ensure robust operation in various environments.

Why Choose This Part

The regulator features a high maximum input voltage of 30V and a low quiescent current of 6mA, making it versatile for different input sources. Its built-in short circuit and thermal shutdown protections prevent device failure during fault conditions. The TO-92 through-hole package is convenient for manual assembly and rapid prototyping.

Applications

On-Card Regulation
Eliminating noise and distribution problems associated with single-point regulation by providing local 5V rails.
Logic Level Supply
Providing a stable 5V source for TTL and CMOS logic circuits in industrial and consumer electronics.
Breadboard Prototyping
Easy integration into solderless breadboards for powering microcontrollers and small sensor arrays.
Current Limiter
Utilizing the internal protection features to act as a current-limiting device in low-power circuits.

Getting Started

To use this regulator, connect a minimum 7V input to pin 3 and ground to pin 2. While the device is stable, it is recommended to place a 0.33uF capacitor on the input and a 0.1uF capacitor on the output as close to the pins as possible to improve transient response and stability.

Also Consider
