Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Note 2: VS = 18V and TA = 25˚C unless otherwise specified. Note 3: Rejection ratio referred to the output with CBYPASS =5µF. 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: CBYPASS = 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. www.national.com 3 |
