Range. Unless otherwise specified: V+ = 5V, FC = Open, C
Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: OUT may be shorted to GND for one second without damage. However, shorting OUT to V+ may damage the device and should be avoided. Also, for
temperatures above 85°C, OUT must not be shorted to GND or V+, or device may be damaged.
