NCV8675 Datasheet, PDF (1/15 Pages) ON Semiconductor – 350 mA Very Low Iq Low Dropout Linear Regulator with Reset and Reset Delay

NCV8675
350 mA Very Low I_q Low
Dropout Linear Regulator
with Reset and Reset Delay
The NCV8675 is a precision 5.0 V and 3.3 V fixed output, low
dropout integrated voltage regulator with an output current capability
of 350 mA. Careful management of light load current consumption,
combined with a low leakage process, achieve a typical quiescent
ground current of 34 mA.
NCV8675 is pin for pin compatible with NCV4275 and it could
replace this part when very low quiescent current is required.
The output voltage is accurate within ±2.0%, and maximum dropout
voltage is 600 mV at full rated load current.
It is internally protected against input transients, input supply
reversal, output overcurrent faults, and excess die temperature. No
external components are required to enable these features.
