Product Description
The SmartOR
TM
CMPWR130 is a low dropout regulator
that delivers up to 300mA of load current at a fixed 3.3V
output. An internal threshold level (TYP 4.1V) is used to
prevent the regulator from being operated below dropout
voltage. The device continuously monitors the input
supply and will automatically disable the regulator when
V
falls below the threshold level. When the regulator is
disabled, the control signal “Drive” (Active Low) is
enabled, which allows an external PMOS switch to
power the load from an auxiliary 3.3V supply.
Applications
PCI adapter cards
Network Interface Cards (NIC’s)
Dual power systems
Systems with standby capabilities
C1670101
When V
is restored to a level above the select thresh-
old, the control signal for the external PMOS switch is
disabled and the regulator is once again enabled.
All the necessary control circuitry needed to provide a
smooth and automatic transition between the supplies
has been incorporated. This allows V
to be dynamically
switched without loss of output voltage.
