(1) The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a tolerance of 1% with 100 ppm/°C or better temperature stability.
(2) A low-leakage (<100 nA), open-drain device, such as MOSFET or voltage supervisor IC, is recommended to control pin 14. The open-circuit voltage is less than 5 Vdc.
(3) This control pin has an internal pullup. If it is left open-circuit, the module operates when input power is applied. A small, low-leakage (<100 nA) MOSFET is recommended for control. The open-circuit voltage is less than 5 Vdc. For additional information, see the related application note.
(4) A 470 µF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimum of 500 mA rms of ripple current.
(5) A minimum value of external output capacitor is required for proper operation. Adding additional capacitance at the load further improves transient response. See the Capacitor Application Information section for more guidance.
(6) This is the calculated maximum. This value includes both ceramic and non-ceramic capacitors. The minimum ESR requirement often results in a lower value. See the related Application Information for more guidance.
(7) This is the minimum ESR for all the electrolytic (nonceramic) capacitance. Use 5 mΩ as the minimum when using manufacturer's max-ESR values to calculate.
(8) Minimum capacitance will be determined by your transient deviation requirement. A corresponding resistor, RTT is required for proper operation. See the TurboTrans Selection section for guidance in selecting the capacitance and RTT value.
(9) This is the calculated maximum. This value includes both ceramic and non-ceramic capacitors.
(10) When calculating the Capacitance × ESR product use the capacitance and ESR values of a single capacitor. For an output capacitor bank of several capacitor types and values, calculate the C × ESR product using the values of the capacitor that makes up the majority of the capacitance.
