Pin Length (0.40 ) A = Surface-Mount Tin/Lead Solder Ball Output Voltage Code Y = DDR Module Notes Rating is conditional on the module being soldered to a 4 layer PCB with oz. copper. See the SOA curves or contact the factory for appropriate derating. This control pin has an internal pull-up to the input voltage. If it is left open-circuit the module will operate when input power is applied. A small low-leakage (<00 na) MOSFET is recommended for control. For further information, consult Application Note 9. 3 An input capacitor is required for proper operation. The capacitor must be rated for a minimum of 500 ma rms (000 ma for V input) of ripple current. For further information, consult Application Note 9 on capacitor selection. 4 The typical value of external output capacitance value ensures that V TT meets the specified transient performance requirements for the memory bus terminations. Lower values of capacitance may be possible when the measured peak change in output current is consistently less than 3 A. Test conditions were 5 A/µs load step, -.5 A to +.5 A. 5 This is the calculated maximum. The minimum ESR limitation will often result in a lower value. Consult Application Note 9 for further details. This is the typical ESR for all the electrolytic (non-ceramic) output capacitance. Use mω as the minimum when using max-esr values to calculate. Tape and reel packaging only available on the surface-mount versions. To order Pb-free (RoHS compatible) surface-mount parts replace the mounting option S with Z, e.g. PTHXX00YAZ. To order Pbfree (RoHS compatible) through-hole parts replace the mounting option H with D, e.g. PTHXX00YAD. 9 NOTICE: Some models do not support all options.
