NCP4683

300 mA, Low Dropout

Regulator

The NCP4683 is a CMOS Linear voltage regulator with 300 mA

output current capability. The device has high output voltage accuracy,

low supply current and high ripple rejection. The NCP4683 is easy to

use, with output current fold−back protection circuit included. A Chip

Enable function is included to save power by lowering supply current.

The line and load transient responses are very good, thus this regulator

is suitable for use as a power supply for communication equipment.

Features

• Operating Input Voltage Range: 1.40 V to 5.25 V

• Output Voltage Range: 0.8 V to 3.6 V (available in 0.1 V steps)

• Output Voltage Accuracy: ±1.0% (VOUT > 2.0 V)

• Supply Current: 50 mA

• Dropout Voltage: 0.25 V (IOUT = 300 mA, VOUT = 2.8 V)

• High PSRR: 70 dB (f = 1 kHz)

• Line Regulation: 0.02%/V Typ.

• Stable with Ceramic Capacitors: 1.0 mF or more

• Current Fold Back Protection

• Available in UDFN4 1.0 x 1.0 mm, SC−70, SOT23 Packages

• These are Pb−Free Devices

Typical Applications

• Battery−powered Equipment

• Networking and Communication Equipment

• Cameras, DVRs, STB and Camcorders

• Home Appliances
