Notes: (1) See SOA curves or consult factory for the appropriate derating.
(2) The Inhibit control (pin 1) has an internal pull-up, 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.
(3) The regulator requires a minimum of 100 F input capacitor with a minimum 300 mArms ripple current rating. For further information, consult the
related application note on Capacitor Recommendations.
(4) An external output capacitor is not required for basic operation. Adding 100 F of distributed capacitance at the load will improve the transient response.
