Overview

The MC78L05ABPG is a low-current, fixed positive voltage regulator capable of delivering 100mA of output current. It converts input voltages up to 30V down to a stable 5V rail, making it a standard choice for local on-card regulation. This version comes in a through-hole TO-92 package and is rated for a wide operating temperature range of -40C to 125C.

Why Choose This Part

The IC features internal short circuit current limiting and thermal overload protection, making it essentially indestructible in typical applications. Its TO-92 form factor is ideal for space-constrained through-hole designs and breadboard prototyping.

Applications

Local On-Card Regulation
Eliminates noise and distribution problems associated with single-point regulation by providing 5V locally to digital logic.
Current Limiter
Utilized in circuits requiring a simple fixed current source when combined with a single external resistor.
Consumer Electronics
Provides low-noise power for microcontrollers and sensors in small appliances and handheld devices.
Industrial Control Systems
Used in instrumentation and monitoring equipment where ruggedness and thermal protection are required.

Getting Started

To use this regulator, connect the input pin to a DC source between 7V and 30V, and connect the ground pin to your common rail. It is recommended to place a 0.33uF ceramic capacitor on the input and a 0.1uF capacitor on the output to improve stability and transient response.
