Regulated Output Voltage

This pin is to be connected to the Rsense resistors on the output. The

linear regulator will attempt to maintain 0.9 V between this pin and

ground. Refer to Figure 1 for the equation.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit

values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,

damage may occur and reliability may be affected.
