Electrical Characteristics
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device
is functional, but do not guarantee specific performance limits.
Note 2: Unless otherwise noted, these specifications apply: −25°C
is internally limited, these specifications are applicable for power dissipations up to 625mW. I
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are
covered under the specification for thermal regulation.
Note 4: Thermal resistance of the TO-92 package is 180°C/W junction to ambient with 0.4 leads from a PC board and 160°C/W junction to ambient with 0.125
lead length to PC board.
Note 5: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin.
