NCP4681, NCP4684
150 mA, Ultra Low
Quiescent Current, Low
Dropout Regulator
The NCP4681 and NCP4684 are CMOS Linear voltage regulators
with 150 mA output current capability and ultra low supply currents
(1 mA typ.) The devices are easy to use and include output current
protection and a fully integrated soft−start circuit to minimize inrush
current and to ensure no output voltage overshoot. The NCP4681
includes an Enable function to reduce supply current by using a
Standby mode, while the NCP4684 excludes the Enable pin to avoid
any pull down current, thereby offering the lowest possible current
consumption for battery powered applications in Active mode. For
portable products the devices are available in the exceptionally small
0.8 x 0.8 mm XDFN, along with the SC−70 and SOT23 packages
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%
• Supply Current: 1 mA (excluding the CE pull down current)
• Dropout Voltage: 0.28 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
• Build−in Constant Slope Circuit for soft−start function
• Available in XDFN4 0.8 x 0.8 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
