DESCRIPTION
The L4931 series are very Low Drop regulators
available in TO-220, SO-8, DPAK, PPAK and
TO-92 packages and in a wide range of output
voltages.
The very Low Drop voltage (0.4V) and the very
low quiescent current make them particularly
suitable for Low Noise, Low Power applications
and specially in battery powered systems.
SCHEMATIC DIAGRAM
January 2004
VERY LOW DROPOUT VOLTAGE (0.4V)
VERY LOW QUIESCENT CURRENT
(TYP. 50 µA IN OFF MODE, 600µA IN ON
MODE)
OUTPUT CURRENT UP TO 250 mA
LOGIC-CONTROLLED ELECTRONIC
SHUTDOWN
OUTPUT VOLTAGES OF 1.25; 1.5; 2.5; 2.7;
3; 3.3; 3.5; 4; 4.5; 4.7; 5; 5.2; 5.5; 6; 8; 12V
INTERNAL CURRENT AND THERMAL LIMIT
ONLY 2.2µF FOR STABILITY
AVAILABLE IN ± 1% (AB) OR 2% (C)
SELECTION AT 25°C
SUPPLY VOLTAGE REJECTION: 70db TYP.
FOR 5V VERSION
TEMPERATURE RANGE: -40 TO 125°C
VOLTAGE REGULATORS WITH INHIBIT
In PPAK and SO-8 packages a Shutdown Logic
Control function is available TTL compatible. This
means that when the device is used as a local
regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.
It requires only a 2.2 µF capacitor for stability
allowing space and cost saving.
