Note 1) The specified condition Tj=25˚C means that the test should be carried out with the test time so short (within 10ms) that the
drift in characteristic value due to the rise in chip junction temperature can be ignored.
Note 2) Unless otherwise specified, VI=–23V, IO=500mA, CI=2µF, CO=1µF, Tj=0 to 125˚C
