until c d reaches to the threshold value. once c d value becomes more than the threshold value, d out outputs ?h?. in the case of r1510sxxxc/d, if the monitor voltage becomes lower than the detector threshold, the capacitor of c d starts to get discharged. therefore, if the monitor voltage becomes more than the released voltage without electrical dischar ge, the release output delay time afterwards becomes less than the existing release output delay time (t delay ). 4.97 4.98 4.99 5.00 5.01 5.02 5.03 0 1020304050 output current i out (ma) output voltage v out (v) from low-power consumption mode to hi g h-speed mode from high-speed mode to l o w- po w e r co n su m pt i o n m ode r1510s no.ea-185-140724 17 monitor voltage (v dd or v out ) delay pin voltage (c d ) output voltage (d out ) release output delay time (t delay ) detect output delay time (t reset ) gnd gnd low level high level gnd detector threshold (-v det ) release voltage (+v det ) r1510sxxxc/d if v in voltage is raised suddenly from the less than the mi nimum operating voltage to the less than the release voltage, v in voltage momentarily passes through the unstable ra nge (from 0v to the minimum operating voltage), therefore, d out may output ?h?
