Notes: (1) See SOA curves or consult factory for appropriate derating.
(2) The minimum input voltage is equal to 2.95 V or Vout + 0.65 V, whichever is greater.
(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 small low-leakage (<100 nA) MOSFET is recommended to control this pin. The open-circuit voltage is less than 1 Vdc.
(5) This control pin has an internal pull-up to the input voltage Vin. 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.
(6) A 470-F electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 700 mArms of ripple current.
(7) An external output capacitor is not required for basic operation. Adding 330 F of distributed capacitance at the load will improve the transient response.
(8) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance.
(9) This is the typical ESR for all the electrolytic (non-ceramic) ouput capacitance. Use 7 m
as the minimum when using max-ESR values to calculate.
