Технические характеристики
This component is a high-current low-noise adjustable low dropout linear regulator manufactured by SGMICRO, designed for high-stability power supply conversion with large output current and ultra-low voltage drop performance.
Определение номера детали
SGM2208 refers to the core model of the adjustable high-current LDO series. XPTS16G stands for TSSOP-16 package with exposed thermal pad and green lead-free process. TR denotes tape-and-reel bulk packaging for automatic SMT mounting in mass production.
Core Electrical Parameters
The device supports maximum continuous output current up to 3A, with a typical dropout voltage of only 155mV under full load condition. The input voltage relative to output terminal ranges from 0V to 24V, and the bias supply voltage covers 2.7V to 25V. Output voltage can be precisely set via a single external resistor, and the output level is allowed to be adjusted down to 0V. Typical output noise is 32μVRMS, with power supply rejection ratio reaching 55dB at 1kHz frequency. Built-in overcurrent limit protection and thermal shutdown function to avoid chip damage under overload and overheating conditions.
Package and Assembly Specifications
Package form is TSSOP-16 with exposed pad for enhanced heat dissipation, which effectively reduces junction temperature during high-current operation. Moisture sensitivity level is MSL 3, and reflow soldering procedures need to be completed within 168 hours after opening vacuum sealed packaging. Standard reel packaging contains 4000 pieces per reel to match automated production line placement equipment.
Environmental and Reliability Standards
Operating temperature range spans from -40℃ to +125℃, adapting to industrial control, automotive and outdoor electronic equipment working conditions. The whole product adopts lead-free and halogen-free manufacturing process, complying with universal environmental restriction requirements. The internal circuit structure has strong anti-interference ability to guarantee stable voltage output under complex electromagnetic environments.
