12V, 2.8A Step-Down Voltage Regulator D30V30F12 Category_Mechanics and Materials/Robot Frames The XBee S2C module hasThis small synchronous switching step down (or buck) regulator takes an input voltage of up to 45 V and efficiently reduces it to 12 V. The board measures only 0. 7 0. 8 yet delivers typical maximum continuous output currents between 1. 5 A and 3. 5 A , depending on the input voltage. An optional enable input can put the regulator in a low power state with a current draw of 10 A to 20 A per volt on VIN. The regulator also features reverse voltage
