NOTES:
3. Specifications at -40°C and +85°C are guaranteed by 25°C test with margin limits.
4. This is the V IN current consumed when the device is active but not switching. Does not include gate drive current.
5. The dropout voltage is defined as VIN - VOUT, when VOUT is 50mV below the value of VOUT for VIN = VOUT + 0.5V.
6. The RESET timeout period is linear with CT at the slope of 2.5ms/nF. Thus, at 10nF (0.01 μ F) the RESET time is 25ms; at 1000nF (0.1 μ F) the
RESET time would be 250ms.
7. Guaranteed by design, not production tested.
8. Add the external feedback resistor mismatch error to get initial V OUT accuracy.
