Overview
MC33565 Smart Voltage Regulator for Peripheral Card Applications The MC33565 Low Drop Out Voltage Regulator is designed for computer peripheral card applications, allowing glitch−free transitions from “sleep” to “active” system modes.
It has internal logic circuitry to detect whether there is a 5.
0 V supply (“active” system mode) or an auxiliary 3.
3 V supply (“sleep” system mode).
A guaranteed 3.
3 V regulated output voltage at 200 mA is always available even if the main 5.
0 V supply drops out.
The regulated 3.
3 V output voltage is provided by either an internal low dropout voltage regulator or an external P−channel MOSFET switch, depending on the system being in the “active” or “sleep” mode.
Features • Glitch−Free Transition from “Sleep” to “Active” Mode • Compatible with Instantly Available PC Systems • Output Current up to 200 mA • Output Regulated to 2% over Temperature • Excellent Line and Load Regulation (0.
4%) • Prevents Reverse Current Flow during Sleep Mode • Short Circuit Pro...
