LM2940-N/LM2940C 1A Low Dropout Regulator

Check for Samples: LM2940-N, LM2940C

FEATURES

DESCRIPTION

The LM2940-N/LM2940C positive voltage regulator

•

Dropout Voltage Typically 0.5V @I_O= 1A

Output Current in Excess of 1A

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 30 mA. Higher

quiescent currents only exist when the regulator is in

the dropout mode (V_IN− V_OUT≤ 3V).

Output Voltage Trimmed Before Assembly

Reverse Battery Protection

Internal Short Circuit Current Limit

Mirror Image Insertion Protection

P⁺Product Enhancement Tested

Designed also for vehicular applications, the LM2940-

N/LM2940C 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/LM2940C cannot

be harmed by temporary mirror-image insertion.

Familiar regulator features such as short circuit and

thermal overload protection are also provided.

Typical Application

*Required if regulator is located far from power supply filter.

**C_OUTmust be at least 22 μF to maintain stability. May be increased without bound to maintain regulation during

transients. Locate as close as possible to the regulator. This capacitor must be rated over the same operating

temperature range as the regulator and the ESR is critical; see curve.
