ELECTRICAL CHARACTERISTICS (continued)
Boldface limits apply over the specified temperature range, TA = –40°C to +125°C.
At TA = +25°C, VS = +5V, GND = 0V, DOUT/VCLAMP = +5V, and VREF = +5V, unless otherwise noted.

IREF current load is typically 100mA while in Shutdown mode. Although the output amplifier is disabled in Shutdown mode, RFO and
RGO (180k
typical total) remain connected in series between VFB and GND while in Shutdown mode. See Figure 37, Detailed Block
Diagram, for more information.
