NCP4620
150 mA, 10 V, Low Dropout
Regulator
The NCP4620 is a CMOS Linear voltage regulator with 150 mA
output current capability. The device is capable of operating with input
voltages up to 10 V, with high output voltage accuracy and low
temperature−drift coefficient. The NCP4620 is easy to use, with
output current fold−back protection and a thermal shutdown circuit
included. A Chip Enable function is included to save power by
lowering supply current.
Features
• Operating Input Voltage Range: 2.6 V to 10 V
• Output Voltage Range: 1.2 V to 6.0 V (available in 0.1 V steps)
• Output Voltage Accuracy: ±1.0%
• Low Supply Current: 23 mA
• Low Dropout: 165 mV (I
OUT

• High PSRR: 70 dB at 1 kHz
• Line Regulation 0.02%/V Typ
• Current Fold Back Protection
• Thermal Shutdown Protection
• Stable with Ceramic Capacitors
• Available in SC−70 and SOT23 Packages
• These are Pb−Free Devices*
Typical Applications
• Battery products powered by 2 Lithium Ion cells
• Networking and Communication Equipment
• Cameras, DVRs, STB and Camcorders
• Toys, industrial applications
