Datasheet - Electrical Characteristics

6 Electrical Characteristics

VIN = VOUT +0.5V, CIN = 1µF, COUT = 1µF, CBYPASS = 10nF, TAMB = -40 to +85ºC (unless otherwise specified). Typ val-

ues are at TAMB = +25ºC. Limits 100% tested at +25ºC. Limits over operating temperature range guaranteed by design.
