Notes:

a. Room = 25 °C, Full = - 40 to 85 °C. Derate 7.6 mW/°C for TSC75 and 5.5 mW/°C for SOT23 above TA = 70 °C.

b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.

c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

d. Dropout voltage is defined as the input-to-output differential voltage at which the output voltage drops 2 % below its nominal

value with constant load. For outputs = 2.2 V, dropout voltage is not applicable due to 2.2 V minimum input voltage requirement.

e. Ground current is specified for normal operation as well as “drop-out” operation.

f. Output noise is proportional to output voltage. Use formula eN = 60 µV(rms)*VOUT/2.8 V.

g. POK threshold percentage is calculated by VIN/VOUT x 100 %. The POK is measured with a differential voltage across VIN and VOUT until POK

turn on (low threshold) or off (high threshold). For VOUT less than 2.2 V, POK is guaranteed functionality only.
