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.

NOTE 1: Capacitors used in automatic test setup may be different from value suggested.
Capacitor suggested values are:
V+ to GND: 150µF & 0.1µF (01,02,03).
VOUT to CC: 0.15µF (01,02,03).
VREF to GND: 0.01µF (02,03), 4.7µF (01).
Output to GND: 300µF (02,03), 150µF (01).
CC to GND: 2200µF (02,03), 0.15µF (01).
SS to GND: 0.1µF (02,03), 0.15µF (01).
NOTE 2: Circuit will regulate properly with input voltage as high as 5.25V due to voltage drop across the
external diode.
