7 / 12 page 5V/3.3V or Adjustable, High-Efficiency, Low-Dropout, Step-Down DC-DC Controllers _______________________________________________________________________________________ 7 Shutdown Mode When SHDN is high, the MAX1649/MAX1651 enter shut- down mode. In this mode, the internal biasing circuitry is turned off (including the reference) and the supply cur- rent drops to less than 5µA. EXT goes high, turning off the external MOSFET. SHDN is a logic-level input. Connect SHDN to GND for normal operation. Quiescent Current In normal operation, the device's typical quiescent cur- rent is 78µA. In an actual application, even with no load, additional current is drawn to supply external feedback resistors (if used) and the diode and capacitor leakage currents. In the circuit of Figure 1, with V+ at 5V and VOUT at 3.3V, typical no-load supply current for the entire circuit is 90µA.
