Product Summary
The LM2941S is a 1A low dropout adjustable regulator. The LM2941S 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 of the LM2941S 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 of the LM2941S with 1A of output current and an input-output differential of 5V is therefore only 30 mA.
