LM2941/LM2941C

1A Low Dropout Adjustable Regulator

and the load. Familiar regulator features such as short circuit

and thermal overload protection are also provided.

General 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 the entire temperature range.

Furthermore, a quiescent current reduction circuit has been

included which reduces the ground pin current when the dif-

ferential 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 there-

fore only 30mA. Higher quiescent currents only exist when the

regulator is in the dropout mode (V_IN− V_OUT≤ 3V).

Features

LLP space saving package

■

Output voltage adjustable from 5V to 20V

Dropout voltage typically 0.5V @ I_O= 1A

Output current in excess of 1A

Trimmed reference voltage

Reverse battery protection

Internal short circuit current limit

Designed also for vehicular applications, the LM2941 and all

regulated circuitry are protected from reverse battery instal-

lations 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

Mirror image insertion protection

P⁺Product Enhancement tested
