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

-V
OUT
≤3V).
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.
