Bay Linear
Inspire the Linear Power
1.25A High Current Low Dropout
Voltage Regulator for Convert 5V & 3.3V
LM3940
Description
The Bay Linear LM3940 is a 1.25A high accuracy, low dropout
voltage regulator with only 40mV at light loads and
350mV(Typ.)@ 1.0A) and low quiescent current of 240碌A typical.
The LM3940 is designed for low voltage a application that requires
lower dropout voltage and faster transient response. This device is
an excellent choice for use in powering low voltage applications
where require a lower dropout, faster transient response to regulate
from +2.5V to 3.8V supplies and as a post regulator for switching
supplies applications.
The LM3940 offers full protection against over-current faults,
reversed input polarity, reversed load insertion, and positive and
negative transient voltage. On-Chip trimming adjusts the reference
voltage to 1%.
The LM3940 are offered in a 3-pin SOT-223, TO-220 & TO-263
package compatible with other 3 terminal regulators. The LM3940
is also offer in a new LPDD (Low Profile TO-263) package from
4.47 mm (DD) tickness down to only 1.27 mm (LPDD) total
tickness.
