NCP4680/D
NCP4680
150 mA, Low Noise Low
Dropout Regulator
The NCP4680 is a CMOS linear voltage regulator with 150 mA
output current capability. The device is available in a tiny 0.8x0.8 mm
XDFN, and has high output voltage accuracy, low supply current and
high ripple rejection. The NCP4680 is easy to use and includes output
current fold−back protection. A Chip Enable function is included to
save power by lowering supply current. The line and load transient
responses are very good, making this regulator ideal 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%
• Supply Current: 50 mA typical
• Dropout Voltage: 0.25 V (I
OUT
= 150 mA, V
OUT
= 2.5 V)
• High PSRR: 75 dB (f = 1 kHz, V
OUT
= 2.5 V)
• Line Regulation: 0.02%/V Typ.
• Stable with Ceramic Capacitors: 0.1 mF or more
• Current Fold Back Protection
• 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
