Notes:
(1) See SOA curves or consult factory for appropriate derating.
(2) The set-point voltage rolerance is affected be the tolerance and stability of R
SET
. The stated limit is unconditionally met if R
SET
has a tolerance of 1 %
with 100 ppm/°C or better temperature stability.
(3) A small low-leakage (<100 nA) MOSFET is recommended to control this pin. The open-circuit voltage is less than 1 Vdc.
(4) This control pin has an internal pull-up to 5 V nominal. If it is left open-circuit the module will operate when input power is applied. A small low-
leakage (<100 nA) MOSFET is recommended for control. For further information, consult the related application note.
(5) A 560 μF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 500 mArms of ripple current.
(6) An external output capacitor is not required for basic operation. Adding 330 μF of distributed capacitance at the load will improve the transient response.
(7) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance.
(8) This is the typcial ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m
W
as the minimum when using max-ESR values to calculate.
