NCV8675DT50RKG

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 μA. 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% for D²PAK-5 package and ±2.5% for DPAK−5 package, 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. The NCV8675 is an integrated low dropout regulator that provides 5.0 V 350 mA, or 3.3 V 350 mA protected output and a signal for power on reset. The regulation is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference, which gives it the lowest possible drop out voltage and best possible temperature stability. The output current capability is 350 mA, and the base drive quiescent current is controlled to prevent over saturation when the input voltage is low or when the output is overloaded. The regulator is protected by both current limit and thermal shutdown. Thermal shutdown occurs above 150 °C to protect the IC during overloads and extreme ambient temperatures. The delay time for the reset output is adjustable by selection of the timing capacitor.
