NCV4299AD: Linear Voltage Regulator, LDO, 150 mA

Product Description
The NCV4299A is a 150 mA precision micropower voltage regulator available with output voltages of 5.0 V or 3.3 V. It is available in an 14−lead SOIC (fused) and TSSOP-14 EPAD packages. The output voltage is accurate within ±2% with a maximum dropout voltage of 0.5 V at 100 mA for the 5.0 V version. The NCV4299A features low quiescent current of only 65 µA with a 100 µA load.

The device features an adjustable reset output and an adjustable system monitor to provide shutdown early warning. The devices includes an inhibit function to turn the device off while consuming less than 1.0 µA of quiescent current.
