*This is a stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS: TA = -40°C to +85°C, VIN = + 5V, C1 = C2 = 3.3F (TC1682); C1 = C2 =
1
F (TC1683); C1 = C2 = 0.33F (TC1684); SHDN = GND, unless otherwise noted. Typical values are at TA = +25°C
