LM2941S Description
A 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 (VIN − VOUT ≤ 3V).
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 circuits and thermal overload protection are also provided.

Frequently Asked Questions
1.What is the maximum voltage of the lm2941?
The LM2941 can supply up to 1 Amp of current. Note that the maximum input voltage is 26 Volts, so this component is not suitable for 24 Volt rated systems. Pictured above is the typical application circuit using the LM2941 as an adjustable voltage regulator. The reference voltage (measured across ADJ and GND) is 1.275V.
2.Is there a lm2941 adjustable low drop out voltage regulator?
Ideally, we want something with the adjustability of the LM317, but the low dropout characteristics of the LM2950. Fortunately, such a component exists and it is the LM2941 adjustable low drop-out voltage regulator.
3.When is the lm2941 in dropout mode?
Higher quiescent currents only exist when the regulator is in the dropout mode (VIN− VOUT≤3V). Designed also for vehicular applications, the LM2941, and all regulated circuitry are protected from reverse battery installations or two-battery jumps.
4.Is the lm2941 a CMOS compatible on / off switch?
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.
