  1. Bodhilabs VPack Boost Regulator - Square

    Bodhilabs VPack Boost Regulator - Square

    Product Code: 784
    Excl. VAT: £9.50 Incl. VAT: £11.40

    The VPack boost regulator provides a constant output voltage between 3 and 6.5 V from a lower input voltage between 1 and 4.5 V, such as you might get from a two-cell battery pack.

    The unit comes configured to produce an output voltage of 5 V, which is required for TTL digital logic, however resistor RF2 can be changed to adjust the output voltage, such as for 3.3 V applications.
