LM3940

用于 5V 至 3.3V 电压转换的 1A 低压降稳压器

The LM3940 is a 1-A low-dropout regulator designed to provide 3.3 V from a 5-V supply.\n\nThe LM3940 is ideally suited for systems which contain both 5-V and 3.3-V logic, with prime power provided from a 5-V bus.\n\nBecause the LM3940 is a true low dropout regulator, it can hold its 3.3-V output in • Input Voltage Range: 4.5 V to 5.5 V\n• Output Voltage Specified over Temperature\n• Excellent Load Regulation\n• Specified 1-A Output Current\n• Requires only One External Component\n• Built-in Protection against Excess Temperature\n• Short-Circuit Protected;
