† Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification
is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS (0°C TO +85°C)
Electrical Specifications: TA = 0°C to +85°C, VIN = +5V, C1 = C2 = 10 µF (TCM828), C1 = C2 = 3.3 µF (TCM829),
unless otherwise noted. Typical values are at TA = +25°C.
