MICROCIRCUIT DATA SHEET
1A LOW DROPOUT REGULATOR
General DescriptionThe LM2940 positive voltage regulator features the ability to source 1A of ouput 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 30 mA. Higher quiescent currents only
exist when the regulator is in the dropout mode (Vin - Vout < 3V).
Designed also for vehicular applications, the LM2940 and all regulated circuitry are
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 LM2940 cannot be harmed by temporary mirror-image insertion.
Familiar regulator features such as short circuit and thermal overload protection are also
provided.
