PRELIMINARY INFORMATION
50mA CMOS LDO WITH SHUTDOWN,
ERROR OUTPUT AND VREF BYPASS
TC1072
*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.
