MC33566
Smart Voltage Regulator for
Peripheral Card Applications
The MC33566 Low Dropout Regulator is designed for computer
peripheral card applications complying with the
instantly available
requirements
as specified by ACPI objectives. The MC33566 permits
glitchfree transitions from “sleep” to “active” system modes and has
internal logic circuitry to detect whether the system is being powered
from the motherboard main 5.0 V power supply or the 3.3 V aux supply.
The MC33566 provides a regulated output voltage of 3.3 V via
either an internal low dropout 5.0 Vto3.3 V voltage regulator or an
external Pchannel MOSFET, depending on the operating status of the
system in which the card is installed. During normal operating mode
(5.0 V main supply available) the 3.3 V output is provided from the
internal low dropout regulator at an output current of 0.4 A. When the
motherboard enters sleep mode, the MC33566 operates from the 3.3 V
aux supply and routes the aux current to the output via the external
Pchannel MOSFET bypass transistor controlled by the
drive out
pin.
As a result, the output voltage provided to the peripheral card remains
constant at 3.3 V even during host systems transitions to and from
sleep mode.
MC33566 Features:
Output Current up to 0.4 A
Excellent Line and Load Regulation
Low Dropout Voltage
Prevents Reverse Current Flow During Sleep Mode
GlitchFree Transfer from Sleep Mode to Active Mode
