† Stresses above those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. These

are stress ratings only and functional operation of the device

at these or any other conditions above those indicated in the

operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

Note

VOUT(S): Preset value of output voltage; VOUT(A): Actual value of output voltage; VDIF: Definition of I/O voltage

difference = {VIN1 – VOUT(A)}; VOUT(A): Output voltage when IOUT is fixed and VIN = VOUT(S) + 1.0V; VIN1: Input voltage

when the output voltage is 98% VOUT(A).

Electrical Specifications: Unless otherwise specified, VOUT(S) = 4.0V, TA = +25°C (see Note 1).
