MOTOROLA ANALOG IC DEVICE DATA
The MC33565 Low Dropout Regulator is designed for computer
peripheral card applications complying with the instantly available
requirementsas specified by ACPI objectives. The MC33565 permits
glitch–free transitions from “sleep” to “active” system modes and has internal
logic circuitry to detect whether the system is being powered from the
motherboard main 5V power supply or the 3.3V aux supply.
The MC33565 provides a regulated output voltage of 3.3V via either an
internal low drop out 5.0V–to–3.3V voltage regulator or an external P–channel
MOSFET, depending on the operating status of the system in which the card is
installed. During normal operating mode (5V main supply available) the 3.3V
output is provided from the internal low dropout regulator at an output current
of 200mA. When the motherboard enters sleep mode, the MC33565 operates
from the 3.3V aux supply and routes the aux current to the output via the
external P–channel MOSFET bypass transistor controlled by the drive outpin.
As a result, the output voltage provided to the peripheral card remains
constant at 3.3V even during transitions to and from sleep mode.
MC33565 Features:
Output Regulated to 2% Over Temperature
Output current up to 200mA
Excellent Line and Load Regulation
Low Dropout Voltage
Prevents reverse current flow during sleep mode
Glitch–free transfer from sleep mode to active mode
Compatible with Instantly AvailablePC systems
