UTC LM2940 LINEAR INTEGRATED CIRCUIT

1A LOW-DROPOUT VOLTAGE

REGULATOR

DESCRIPTION

TO-263-3

TO-220

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,

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-VOUT≤3V).

SOT-223

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.
