Note 1) The specified condition Tj = 25°C means that the test should be carried out within so short a test time (within 10ms) that the
characteristic value drift due to the chip junction temperature rise can be ignored.
Note 2) Unless otherwise specified, VI = 27V, IO = 40mA, CI = 0.33µF, CO = 0.1µF, Tj = 0 to 125°C (AN78L18) and Tj = 0 to 100°C
