NATIONAL SEMICONDUCTOR LM2941/LM2941C 1A Low Dropout Adjustable Regulator Manual
Update: 28 September, 2023
The LM2941 positive voltage regulator is capable of sourcing 1A of output current with a typical dropout voltage of 0.5V and a maximum of 1V over the entire temperature range. It includes a quiescent current reduction circuit that 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 only 30mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN - VOUT ≤ 3V). 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.
