Rochester Electronics PMIC - Voltage Regulators - Linear MC33565DG

The MC33565DG is a low dropout voltage regulator designed for computer peripheral card applications. It provides a regulated output voltage of 3.3 V at a maximum output current of 200 mA, ensuring reliable performance even when the main 5.0 V supply drops out. The device features internal logic circuitry that allows for glitch-free transitions between "sleep" and "active" system modes, making it compatible with instantly available PC systems. This regulator offers excellent line and load regulation, with a typical variation of 0.4%, and maintains output voltage accuracy within 2% over temperature. It also includes protection against reverse current flow during sleep mode and features short circuit protection for enhanced reliability. The MC33565DG is available in a Pb-free SOIC-8 package, making it suitable for various applications, including Ethernet and PCI/NIC cards.
