Note TC = 25 °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.

: More than 0.1 µF. Required if regulator is located an appreciable distance from power supply filter. You

must use to prevent from the parasitic oscillation.

: More than 47 µF. You must use the Low-impedance-type (low ESR) capacitor.

: Need for VO > VIN

: Need a shottky barrier diode for VO < GND.
