Notes:

(i) For operation below 0 °C the external capacitors m ust bave stable characteristics. use either a low ESR tantalum, Os-Con, or ceramic capacitor.

(ii) During reflow of SMD package version do not elevate peak temperature of the module, pins or internal components above the stated maximum.

Notes: (1) No derating is required when the module is soldered directly to a 4-layer PCB with 1 oz. copper.

with 100 ppm/°C or better temperature stability.

(3) The pk-pk output ripple voltage is measured with an external 10 µF ceramic capacitor. See the standard application schematic.

(4) This control pin has an internal pull-up to the input voltage Vin. If it is left open-circuit the module will operate when input power is applied. A small

low-leakage (<100 nA) MOSFET is recommended for control. For further information, consult the related application note.

(5) A 100 µF input capacitor is required for proper operation. The capacitor must be rated for a minimum of 300 mA rms of ripple current.

(6) An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response.

(7) This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult the application notes for further guidance.

(8) This is the typcial ESR for all the electrolytic (non-ceramic) output capacitance. Use 7 m

Ω as the minimum when using max-ESR values to calculate.
