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: V_S = 18V and T_A = 25˚C unless otherwise specified.
Note 3: Rejection ratio referred to the output with C_BYPASS = 5 µF.
Note 4: With device Pins 3, 4, 5, 10, 11, 12 soldered into a 1/16" epoxy glass board with 2 ounce copper foil with a minimum surface of 6 square inches.
Note 5: C_BYPASS = 0.47 µfd on Pin 1.
Note 6: The maximum junction temperature of the LM380 is 150˚C.
Note 7: The package is to be derated at 15˚C/W junction to heat sink pins for 14-pin pkg; 75˚C/W for 8-pin.
