    | Partname: | LM3940_03 |  | Description: | 1A Low Dropout Regulator for 5V to 3.3V Conversion |  | Manufacturer: | National Semiconductor |  | Datasheet: | PDF (367K). Click here to download *)
 |  | The LM3940 is ideally suited for systems which contain both 5V and 3.3V logic, with prime power provided from a 5V bus. Because the LM3940 is a true low dropout regulator, it can hold its 3.3V output in regulation with input voltages as low as 4.5V. |  |  Click here to download LM3940_03 Datasheet*)
