Electrical Specifications

PARAMETER

Unless otherwise noted, all parameters are guaranteed over the operational supply voltage and temperature

range of the device as follows:

TA = -40°C to +85°C; VIN = (VO + 1.0V) to 6.5V with a minimum VIN of 2.3V; CIN = 1µF; CO = 1µF;

CBYP = 0.01µF. (Continued)
