Notes: (i)
For operation below 0 °C the external capacitors must have stable characteristics. Use either a low ESR tantalum or Oscon capacitor.
(ii)
During solder reflow of SMD package version, do not elevate the case, pin, or internal component temperatures above the stated maximum. For further
guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA051).
(iii)
The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.

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.
