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 autodischarge 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, SOT895 and SOT235 Package
These are PbFree Devices
