Notes:
(1) ISR-will operate down to no load with reduced specifications.
(2) If the remote sense ground is not used, pin 12 must be connected to pin 13 for optimum output voltage accuracy.
(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 (<1μA)
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) 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 requires a minimum output capacitance of 330μF for proper operation. An input capacitance of 1500μF is also required. This
must be rated for a minimum of 1.4Arms 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 20ADC with a typical value of 1μH.
