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 = 23V, IO = 500mA, CI = 0.33µF and CO = 0.1µF.
