NCP4626

300 mA, Low Dropout

Voltage Regulator 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 V, low supply current and

high output voltage accuracy. Through 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 V, comes with or without an auto−discharge feature on the output,

and is available in a choice of XDFN, SOT89 and SOT23 packages.

Features

• Operating Input Voltage Range: 3.5 V to 16.0 V

• Output Voltage Range: 2.0 to 15.0 V (available in 0.1 V steps)

• Low Quiescent current (6 uA typ.) in Low Power Mode

• Dropout Voltage:

550 mV typ. (IOUT = 300 mA, VOUT = 5 V, Fast Mode)

700 mV typ. (IOUT = 300 mA, VOUT = 5 V, Low Power Mode)

• Output Voltage Accuracy: ±1.5% (Fast Mode)

±2.5% (Low Power Mode)

• High PSRR: 60 dB at 1 kHz

• Current Fold Back Protection

• Thermal Shutdown Protection

• Stable with a CIN = 2.2 mF and COUT = 4.7 mF Ceramic Capacitors

• Available in 1.6x1.6 XDFN6, SOT89−5 and SOT23−5 Package

• These are Pb−Free Devices

Typical Applications

• Digital Home Appliances

• Audio Visual Equipment

• Battery backup circuits
