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 µF 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 µF of distributed capacitance at the load will improve the transient response.
