LM2941

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  ange.Furthermore,aquiescentcurrentreductioncircuithas 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  ifferential of 5V is therefore only 30 mA. Higher quiescent currents only exist whentheregulatorisinthedropoutmode(V_IN -V_OUT3V).
 
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  andtheload.Familiarregulatorfeaturessuchasshortcircuit and thermal overload protection are also provided.
