CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.

Electrical Specifications
Unless otherwise noted, all parameters are established over the operational supply voltage and temperature range
of the device as follows: TA = -40°C to +85°C; VIN = (VO + 0.5V) to 6.5V with a minimum VIN of 2.3V; CIN = 1µF; CO
= 1µF.
