(1)

Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest

supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in VTEMP Voltage Shift .

(2)

Source currents are flowing out of the LM57-Q1. Sink currents are flowing into the LM57-Q1. Load Regulation is calculated by

(3)

Supply current refers to the quiescent current of the LM57-Q1 only and does not include any load current

(4)

This current is leakage current only and is therefore highest at high temperatures. Prototype test indicate that the leakage is well below

1

μA over the full temperature range. This 1 μA specification reflects the limitations of measuring leakage at room temperature. For this

reason only, the leakage current is not specified at a lower value.
