Notes: (1) If the remote sense ground is not used, pin 12 must be connected to pin 13 for optimum output voltage accuracy.
(2) The transient response may be improved by placing additional capacitors with low equivalent series resistance (ESR) on the output.
(3) The STBY* control (pin 5) has an internal pull-up. If it is left open-circuit, the module will operate when input power is applied. A low-leakage (<1 A)
MOSFET must be used to control this pin. The open-circuit voltage may be as high as Vin.
(4) For operation below 0 °C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon capacitors.
(5) See safe Operating Area curves or consult factory for the appropriate derating.
(6) During reflow of SMD package version do not elevate the module case, pins, or internal component temperatures above a peak of 215 °C. For further
guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Products,” (SLTA051).
(7) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
External Capacitors: The regulator require a minimum output capacitance of 330 F for proper operation. An input capacitance of 1500 F is also required. This
must be rated for a minimum of 1.1 Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required. For further informa-
tion refer to the application note regarding capacitor selection for this product.
Input Filter: An input filter inductor is optional for most applications. The inductor must be sized to handle 30 ADC with a typical value of 1 H.
