U3V50x Step-Up Voltage Regulators

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 easier to set the output voltage to a particular value.

This family of boost regulators can generate up to 30 V from input voltages as low as 2.9 V while allowing for input currents as high as 5 A and offering typical efficiencies of 80% to 95%. The regulators include built-in reverse-voltage protection, over-current protection, thermal shutdown, and an under-voltage lockout that keeps the modules from behaving erratically when the input voltage gets too low. The U3V50x family includes versions with fixed 5 V, 6 V, 9 V, 12 V, or 24 V outputs and versions with adjustable 4 V to 12 V or 9 V to 30 V outputs:

#2569: U3V50F24	24 V					$31.95
#2570: U3V50ALV	4 V – 12 V					$29.95
#2571: U3V50AHV	9 V – 30 V					$33.95
*Actual achievable maximum continuous current is a function of input and output voltage and is limited by thermal dissipation.
