Linear & Switching Voltage Regulators

SG7905AIG Description

The SG7905AIG is a high-performance linear voltage regulator designed by Microchip Technology, offering a fixed output voltage of -5V and a robust current handling capability of up to 1.5A. This regulator is part of the SG7905 family and is specifically tailored for military-grade applications, ensuring reliability and durability in demanding environments. The device features a negative output configuration, making it ideal for systems requiring a stable negative voltage supply. With a maximum dropout voltage of 2.3V at 500mA, the SG7905AIG ensures efficient power delivery even under varying load conditions. The regulator’s quiescent current is a mere 2.5 mA, contributing to low power consumption and enhanced efficiency. Additionally, the SG7905AIG boasts a power supply rejection ratio (PSRR) of 54dB at 120Hz, effectively filtering out noise and ripple from the input supply. The device is housed in a through-hole TO257 package, ensuring robust mechanical stability and ease of integration into existing circuit designs. The SG7905AIG is REACH unaffected, adhering to stringent environmental regulations, and is available in bulk packaging for large-scale production.
