LM2941/LM2941C 1A Low Dropout Adjustable Regulator

Check for Samples: LM2941, LM2941C

FEATURES

DESCRIPTION

The LM2941 positive voltage regulator features the

ability to source 1A of output current with a typical

dropout voltage of 0.5V and a maximum of 1V over

•

Output Voltage Adjustable From 5V to 20V

Dropout Voltage Typically 0.5V @ I_O= 1A

Output Current in Excess of 1A

Trimmed Reference Voltage

the entire temperature range. Furthermore,

quiescent current reduction circuit has been included

which reduces the ground pin 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).

Reverse Battery Protection

Internal Short Circuit Current Limit

Mirror Image Insertion Protection

P⁺Product Enhancement Tested

TTL, CMOS Compatible ON/OFF Switch

Designed also for vehicular applications, the LM2941

and all regulated circuitry are protected from reverse

battery installations or two-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.

Familiar regulator features such as short circuit and

thermal overload protection are also provided.
