Notes: (1) See SOA curves or consult factory for appropriate derating.
(2) The set-point voltage tolerance is affected by the tolerance and stability ofR SET . The stated limit is unconditionally met if R SET has a tolerance of 1 %
with 100 ppm/°C or better temperature stability.
(3) The Inhibit control (pin 3) has an internal pull-up to Vin, and if left open-circuit the module will operate when input power is applied. A small low-
leakage (<100 nA) MOSFET is recommended to control this input. See application notes for more information.
(4) The regulator requires a minimum of 100 μF input capacitor with a minimum 300 mArms ripple current rating. For further information, consult the
related application note on Capacitor Recommendations.
(5) An external output capacitor is not required for basic operation. Adding 100 μF of distributed capacitance at the load will improve the transient response.
(6) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance.
(7) This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m ? as the minimum when using max-ESR values to calculate.
