(2) The minimum input voltage required by the part is Vout + 1.2 V, or 3.1 V, whichever is greater. (3) The STBY* control (pin 3) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit voltage is the input voltage, Vin. Refer to the application notes for other interface considerations. (4) The module requires a 330 µF output capacitor for proper operation in all applications. For transient or dynamic load applications, additional output capacitance (Cout) may be necessary. The maximum allowable output capacitance is 5,000 µF. (5) In addition, the input capacitance (Cin) must be rated for a minimum of 1.2 Arms ripple current rating. For more information consult the related application note on capacitor recommendations. (6) See Safe Operating Area curves or contact the factory for the appropriate derating. (7) The tab pins on the 16-pin mount package types (suffix L) must be soldered. For more information see the applicable package outline drawing. |
