NCP4686
400 mA, High Accuracy,
Low Input Voltage, Low
Dropout Regulator
The NCP4686 is CMOS Linear voltage regulators with 400 mA
output current capability. The device has very high output voltage
accuracy, low supply current and low ON−resistance transistor. The
NCP4686 is easy to use and includes output current fold−back
protection and a fully integrated constant slope circuit as a soft−start
circuit. Due to it inrush current is minimized and no output voltage
overshoots are there. A Chip Enable function is included to save
power by lowering supply current.
Features
• Operating Input Voltage Range: 1.0 V to 3.6 V
• Output Voltage Range: 0.7 V to 1.8 V (available in 0.1 V steps)
• Output Voltage Accuracy: ±0.8% (VOUT ≥ 1.0 V, TA = 25°C)
• Supply Current: 48 mA
• Dropout Voltage: 0.22 V (VOUT = 1.5 V)
• Line Regulation: 0.1%/V Typ.
• Ripple Rejection: Typ. 60 dB (f = 10 kHz)
• Stable with Ceramic Capacitors: 1 mF or more
• Current Fold Back Protection
• Build−in Constant Slope Circuit
• Available in XDFN6 1.2 x 1.2 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
