Pololu 9V Step-Up Voltage Regulator U3V50F9 Shipping:1 day 2 While the A4990 canThis powerful boost regulator efficiently generates an output voltage of 9 V from an input voltage as low as 2. 9 V while allowing an input current as high as 5 A. Note: We recommend our newer U3V70x family of boost regulators over these older U3V50x regulators for applications that require 20 V or less. The U3V70x regulators are smaller and can deliver more current, and the adjustable version features a precision 12 turn potentiometer, which makes it
