°C, Internally limited
When operating junction temperature rises up to 150
°C, the internal circuit shutdown output voltage.
Caution Exposure to Absolute Maximum Ratings for extended periods may affect device reliability;
exceeding the ratings could cause permanent damage. The parameters apply independently. The
device should be operated within the limits specified under DC and AC Characteristics.

OUTPUT
CIN
: More than 0.1
F. Required if regulator is located an appreciable distance from power supply filter. You
must use to prevent from the parasitic oscillation.
COUT
: More than 47
F. You must use the Low-impedance-type (low ESR) capacitor.
D1
: Need for VO > VIN
D2
: Need a shottky barrier diode for VO < GND.
