RHFL4913KPA1
Overview
The RHFL4913KPA1 is a radiation-hardened positive adjustable linear voltage regulator designed for harsh aerospace and defense environments. It delivers up to 2A of output current with a low dropout voltage of 0.95V at full load, supporting input voltages up to 12V. This regulator is housed in a hermetic 16-pin ceramic Flatpack for high-reliability thermal management and mechanical stability.
Why Choose This Part
This device features advanced protection circuitry including overtemperature, overcurrent, and programmable short-circuit current limits. It also includes remote sensing to ensure accurate voltage regulation at the load and a TTL-compatible control pin for remote shutdown functionality.
Applications
Key Specifications
Getting Started
Designers should follow the recommended layout for the Flat-16P package to ensure proper heat sinking through the package base. Ensure that the external compensation capacitors meet the required ESR range specified in the datasheet to maintain stability across the full 2A load range and operating temperature of -55C to 125C.
