NCV8664ST50T3G

The NCV8664 is a precision 3.3 V and 5.0 V fixed output, low dropout integrated voltage regulator with an output current capability of 150 mA. Careful management of light load current consumption, combined with a low leakage process, achieve a typical quiescent current of 22 μA. The NCV8664 is pin and functionally compatible with NCV4264 and NCV4264−2, and it could replace these parts 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 supply reversal, output overcurrent faults, and excess die temperature. No external components are required to enable these features. The NCV8664 is a precision trimmed 3.3 V and 5.0 V fixed output regulator. Careful management of light load consumption combined with a low leakage process results in a typical quiescent current of 22 μA. The device has current capability of 150 mA, with 600 mV of dropout voltage at full rated load current. The regulation is provided by a PNP pass transistor controlled by an error amplifier with a bandgap reference. The regulator is protected by both current limit and short circuit protection. Thermal shutdown occurs above 150°C to protect the IC during overloads and extreme ambient temperatures.
