NCP4626: Linear Voltage Regulator, LDO, 300 mA, with Reverse Current Protection

The NCP4626 is a CMOS 300 mA low dropout linear regulator with a wide input voltage range of 3.5 V to 16.0 V, low supply current and high output voltage accuracy. Using an ECO mode selector pin the device can be operated in low power mode to reduce quiescent current or fast mode for better transient response and lower dropout. The NCP4626 is suitable for applications where the VOUT pin voltage may be higher than the VIN pin voltage as it is protected against reverse current. The device has a maximum input voltage tolerance of 18.0 V, comes with or without an auto-discharge feature on the output, and is available in a choice of XDFN, SOT89 and SOT23 packages.
