(1) The maximum output current is 1.5 A or the maximum output power is 9 W, whichever is less.
(2) The maximum input voltage is limited and defined to be (32 – |VO|) volts.
(3) The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a
tolerance of 1% with 100 ppm/°C or better temperature stability.
(4) A 100-μF electrolytic capacitor and two 4.7-μF ceramic capacitors are required across the input (VI and GND) for proper operation.
Locate the ceramic capacitance close to the module.
(5) 100 μF of output capacitance is required for proper operation. See the application information for further guidance.
(6) This is the typical ESR for all the electrolytic (nonceramic) capacitance. Use 17 mΩ as the minimum when using maximum ESR values
to calculate.
