LM3940

SNVS114G –MAY 1999–REVISED FEBRUARY 2015
LM3940 1-A Low-Dropout Regulator for 5-Vto 3.3-V Conversion Features
Input Voltage Range: 4.5Vto 5.5V Output Voltage Specified over Temperature Excellent Load Regulation Specified 1-A Output Current Requires only One External Component Built-in Protection against Excess Temperature Short-Circuit Protected Applications Laptop and Desktop Computers Logic Systems Description
The LM3940isa 1-A low-dropout regulator designed provide 3.3V froma 5-V supply.
The LM3940is ideally suited for systems which
contain both 5-V and 3.3-V logic, with prime power
provided froma 5-V bus.
Because the LM3940isa true low dropout regulator, can hold its 3.3-V outputin regulation with input
voltagesas lowas 4.5V.
The TO-220 packageof the LM3940 means thatin
most applications the full1Aof load current can be
delivered without usingan additional heatsink.
The surface mount DDPAK/TO-263 package uses
minimum board space, and gives excellent power
dissipation capability when soldered toa copper
planeon the PC board.
