Part Number: LP2985


Hi

customer want to get LP2985A-50DBVR output voltage VS Temperature curve @ 12V input 50mA output

but in datasheet, there is no this curve, only other input voltage curve are shown.

could you help to test and send this curve to me?

thanks.

    Hi Max,

    The worst-case output accuracy for the LP2985A for your customer's application can be estimated using the electrical characteristics table. For the following data, Vin = 6 V when Vout(nom) = 5 V. At Vin = 12 V the regulator's line regulation spec will reduce the output voltage accuracy. 

    Accuracy = Output voltage tolerance + Line regulation * delta(Vin) = 2.5% + 0.032 %/V * (12-6) V = 2.7%

    As such, the worst-case output voltage range for the LP2985A is approximately 4.865 V to 5.135 V when Vin = 12 V, Vout = 5 V, and Iout = 50 mA. 

    Thanks,

    Gerard
