TC1072

ABSOLUTE MAXIMUM RATINGS*

Input Voltage .................................................................7V

Output Voltage .................................. (– 0.3) to (VIN + 0.3)

Power Dissipation .................... Internally Limited (Note 7)

Operating Temperature .................... – 40°C < TJ < 125°C

Storage Temperature ............................ – 65°C to +150°C

Maximum Voltage on Any Pin ........... VIN + 0.3V to – 0.3V

Lead Temperature (Soldering, 10 Sec.) ................ +260°C

*Stresses beyond those listed under "Absolute Maximum Ratings" may

cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond

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: VIN = VOUT + 1V, IL = 0.1mA, CL = 3.3µF, SHDN > VIH, TA = 25°C, unless other-

wise specified.BOLDFACE type specifications apply for junction temperatures of

– 40°C to +125°C.
