NCP4682, NCP4685
150 mA, Ultra Low Supply
Current, Low Dropout
Regulator
The NCP4682 and NCP4685 are CMOS Low Dropout Linear
voltage regulators with 150 mA output current capability. The devices
have high output voltage accuracy, a 1 mA (typ.) ultra low supply
current and high ripple rejection. Current fold−back protection is
integrated in the devices to protect against over current and short
current conditions. A Chip Enable (NCP4682 only) function is
included to save power by further lowering supply current, which is
advantageous for battery powered applications. The NCP4685 is
optimized for the lowest quiescent current possible in applications
where the device is always on.
Features
• Operating Input Voltage Range: 1.70 V to 5.25 V
• Output Voltage Range: 1.2 V to 3.3 V (available in 0.1 V steps)
• Output Voltage Accuracy: ±0.8%
• Excellent Output Voltage Temperature Coefficient : ±40 ppm/°C
• Supply Current: 1.0 mA (excluding CE pull down current)
• Standby Current: 0.1 mA
• Dropout Voltage: 0.24 V (IOUT = 150 mA, VOUT = 2.8 V)
• Line Regulation: 0.02%/V Typ.
• Stable with Ceramic Capacitors: 0.1 mF or more
• Current Fold Back Protection
• Available in UDFN4 1.0 x 1.0 mm, SC−82AB, SOT23 Packages
• These are Pb−Free Devices
Typical Applications
• Battery−Powered Equipment
• Networking and Communication Equipment
• Cameras, DVRs, STB and Camcorders
• Home Appliances
