  • Can anyone confirm that this is the same voltage regulator that is used on the nRF24L01-RP-SMA (WRL-00705)? The EAGLE schematic indicates that this is the correct package size, the PDF schematic says that it is a LDO voltage regulator, and the web page indicates that the regulator rated for 3.3V.
