Note 1. Unless otherwise otherwise specified, TA = +25°C, VIN = V+ = VC = 12V, V– = 0, VOUT = 5V,
IL = 1mA, RSC = 0, C! = 100pF, CREF = 0 and divider impedance as seen by error amplifier
≤ 10kΩ. Line and load regulation specifications are given for the condition of constant chip
temperature. Temperature drifts must be taken into account separately for high dissipation
conditions.
Note 2. Guaranteed by correlation to other tests.
Note 3. For metal can applications where VZ is required, an external 6.2V zener diode should be con-
nected in series with VOUT.
