350 mA Very Low Iq Low Dropout Linear Regulator with Reset and Reset Delay

ON Semiconductor 

NCV8675

350 mA Very Low Iq 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.
