DESCRIPTION

The UTC LM2940 is a positive voltage regulator features the

ability to source 1A of output current with a dropout voltage of

typically 0.5V and a maximum of 1V over the entire temperature

range. Furthermore, a quiescent current reduction circuit has

been included which reduces the ground current when the

differential between the input voltage and the output voltage

exceeds approximately 3V.The quiescent current with 1A of

output current and an input-output differential of 5V is therefore

only 30mA.Higher quiescent currents only exist when the

regulator is in the dropout mode (V_IN-V_OUT≤3V).

SOP-16

DIP-16

*Pb-free plating product number: LM2940L

Designed also for vehicular applications, the UTC LM2940 is

protected from reverse battery installations or 2-battery jumps.

During line transients, such as load dump when the input voltage

can momentarily exceed the specified maximum operating

voltage, the regulator will automatically shut down to protect both

the internal circuits and the load. The UTC LM2940 cannot be

harmed by temporary mirror-image insertion. Familiar regulator

features such as short circuit and thermal overload protection are

also provided.
