General Description Connection Diagram/Ordering Information

The LM3940 is a 1A low dropout regulator designed to

provide 3.3V from a 5V supply.

The LM3940 is ideally suited for systems which contain both

5V and 3.3V logic, with prime power provided from a 5V bus.

Because the LM3940 is a true low dropout regulator, it can

hold its 3.3V output in regulation with input voltages as low

as 4.5V.

The T0-220 package of the LM3940 means that in most

applications the full 1A of load current can be delivered

without using an additional heatsink.

The surface mount TO-263 package uses minimum board

space, and gives excellent power dissipation capability when

soldered to a copper plane on the PC board.

Features

♦ Output voltage specified over temperature

♦ Excellent load regulation

♦ Guaranteed 1A output current

♦ Requires only one external component

♦ Built-in protection against excess temperature

♦ Short circuit protected

Applications

♦ Laptop/Desktop Computers

♦ Logic Systems
