Electrical Characteristics
over the full operating temperature range. Unless otherwise specified: V
C
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for which the device
is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications, see Electrical Characteristics. Specifications do not
apply when operating the device outside of its rated operating conditions.
Note 2: At elevated temperatures, device power dissipation must be derated based on package thermal resistance and heatsink thermal values. θ
devices is 65˚C/W if no heatsink is used. If the TO-220 device is attached to a heatsink, a θ
approximately 40˚C/W if soldered down to a copper plane which is at least 1.5 square inches in area. θ
If power dissipation causes the junction temperature to exceed specified limits, the device will go into thermal shutdown.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin.
Note 4: Typical numbers represent the most likely parametric norm for 25˚C operation.
Note 5: Limits are guaranteed through testing, statistical correlation, or design.
Note 6: If used in a dual-supply system where the regulator load is returned to a negative supply, the output pin must be diode clamped to ground.
Note 7: Output voltage line regulation is defined as the change in output voltage from nominal value resulting from a change in input voltage.
Note 8: Output voltage load regulation is defined as the change in output voltage from nominal value as the load current increases from no load to full load.
Note 9: Dropout voltage is defined as the minimum input to output differential required to maintain the output with 2% of nominal value. The PSOP-8 package
devices have a slightly higher dropout voltage due to increased band wire resistance.
Note 10: The machine model is a 220 pF capacitor discharged directly into each pin. The machine model ESD rating of pin 5 is 100V.
