6 Electrical Characteristics
All limits are guaranteed. The parameters with Min and Max values are guaranteed by production tests or SQC (Statistical Quality Control)
methods.
V
IN = 1.5V, C1 = C2 = 22µF, CREF = 100nF, Typical values are at TAMB = +25ºC. Unless otherwise specified. All limits are guaranteed. The
parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods.
