NCP4620

150 mA, 10 V, Low Dropout Regulator

ON Semiconductor 

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 (IOUT = 100 mA, VOUT = 3.3 V)

400 mV (IOUT = 150 mA, VOUT = 2.8 V)

• 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
