These boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can typically be as high as 5 A.
The U3V50x regulator family also includes two adjustable-output versions: the U3V50ALV offers an output range of 4 V to 12 V and the U3V50AHVoffers an output range of 9 V to 30 V. The different versions of the board all look very similar, so the bottom silkscreen includes a blank space where you can add your own distinguishing marks or labels.
The no-load quiescent current depends on the difference between the input and the output voltage. When the two are close, the quiescent current can be less then a milliamp (e.g. 0.6 mA with 5 V in and 6 V out); when the two are far apart, it might be in the tens of milliamps (e.g. 24 mA with 3 V in and 24 V out). The ENABLE pin can be used to put the board in a low-power state that reduces the quiescent current to approximately 20 µA per volt on VIN.
This regulator has built-in reverse-voltage protection, over-current protection, thermal shutdown (which typically activates at 165°C), and an under-voltage lockout that causes the regulator to turn off when the input voltage is below 2.5 V (typical).
