DIOAS78L05RTR-E1
Overview
The AS78L05RTR-E1 is a three-terminal fixed positive linear voltage regulator designed to deliver a stable 5V output at up to 100mA. It supports a wide input voltage range up to 30V and is housed in a compact SOT-89 surface-mount package. This regulator is an effective solution for local on-card regulation, eliminating noise and distribution problems associated with single-point regulation.
Why Choose This Part
The device features internal short circuit current limiting and thermal overload protection to ensure robust operation under fault conditions. It requires no external components for basic operation, though output capacitors are recommended for improved transient response. Its wide operating temperature range of -40C to 125C makes it suitable for demanding thermal environments.
Applications
Key Specifications
Getting Started
When integrating 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. Ensure the SOT-89 thermal pad is soldered to a sufficient copper area on the PCB to manage heat dissipation, especially when operating with high input-to-output voltage differentials.
