LM2941/LM2941C

1A Low Dropout Adjustable Regulator

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.

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 differential between the input voltage and the output volt-

age 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).

Features

n Output voltage adjustable from 5V to 20V

n Dropout voltage typically 0.5V I_O1A

n Output current in excess of 1A

n Trimmed reference voltage

n Reverse battery protection

n Internal short circuit current limit

n Mirror image insertion protection

n P⁺Product Enhancement tested

n TTL, CMOS compatible ON/OFF switch

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
