  • No standby current consumption (or zero).
  • Built-in thermal shutdown circuit.
  • Small package : SOIC10 Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum power source voltage V CC max -0.3 to +20 V Applied output voltage V OUT max -0.3 to +20 V Applied input voltage V IN max -0.3 to +18 V GND pin outflow current I GND 800 mA Allowable power consumption Pd max Mounted on the specified board * 820 mW Operating temperature Topr -30 to +85 °C Storage temperature Tstg -40 to +150 °C * Specified board: 114.3mm × 76.1mm × 1.6mm, glass epoxy board. Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
