NCP4586
150 mA, Low Noise, Low
Dropout Regulator
The NCP4586 is a CMOS 150 mA low dropout linear with low
noise, high ripple rejection, low dropout, high output voltage accuracy
and low supply current. The device is available in three
configurations: enable high, enable low and enable high plus
auto−discharge. Small packages allow mounting on high density
PCBs. This is an excellent general purpose regulator, well suited to
many applications.
Features
• Operating Input Voltage Range: 1.7 V to 6.5 V
• Output Voltage Range: 1.2 to 5.0 V (available in 0.1 V steps)
• Very Low Dropout: 320 mV Typ. at 150 mA
• ±1% Output Voltage Accuracy (VOUT > 2 V, TJ = 25°C)
• High PSRR: 80 dB at 1 kHz
• Current Fold Back Protection
• Stable with a 0.47 mF Ceramic Capacitors
• Available in 1.0 x 1.0 UDFN, SC−82AB and SOT23−5 Package
• These are Pb−Free Devices
Typical Applications
• Battery Powered Equipment
• Portable Communication Equipment
• Cameras, MP3 Players and Camcorder
• High Stability Voltage Reference
