LM2940 -N / LM2940C 1A低压降稳压器 LM2940-N/LM2940C 1A Low Dropout Regulator

This LDO linear regulator developed by Texas Instruments keeps the power stable! Its typical dropout voltage at current is 0.11@100mA|0.5@1A V. This voltage regulation device"s single output can produce a current up to 1Min A. With a small input voltage of 13.6 V and a max of 26 V, this will supply sufficient power to your circuit. With a fixed output that has a voltage of 12 V, this is power management at its best. At a load regulation of 120mV and line regulation of 120mV a constant current can be produced at the output of your circuit. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. The maximum dropout voltage is 0.8@1A|0.15@100mA V. This voltage regulation device has an operating temperature range of -40 °C to 125 °C. Its polarity is positive.
