ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VIN = 2.5V to 60V, unless otherwise noted (Note 2). UV = 2.5V, OV = 0V, SHDN = 2.5V, SENSE = VOUT = VIN unless otherwise specified. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS VIN, VOUT, SENSE
