NCP585

Tri−Mode 300 mA CMOS

LDO Regulator with Enable

The NCP585 series of low dropout regulators are designed for

portable battery powered applications which require precise output

voltage accuracy, low supply current, and high ripple rejection.

These devices feature an enable function which lowers current

consumption significantly and are offered in the SOT23−5 and the

HSON−6 packages.

This series of devices have three modes. Chip Enable (CE mode),

Fast Transient Mode (FT mode), and Low Power Mode (LP mode).

Both the FT and LP mode are utilized via the ECO pin.

Features

• Low Dropout Voltage of 480 mV at 300 mA, Output Voltage = 1.0 V

310 mV at 300 mA, Output Voltage = 1.5 V

230 mV at 300 mA, Output Voltage = 3.0 V

• Excellent Line and Load Regulation

• High Output Voltage Accuracy of ±2% (±3% LP mode)

• Ultra−Low Supply Current of:

3.5

mA (LP mode, Output Voltage < 1.6 V)

80

mA (FT mode, Output Voltage < 1.8 V)

60

mA (FT mode, Output Voltage ≥ 1.8 V)

• Excellent Power Supply Rejection Ratio of 65 dB

• Output Voltage Options: 0.9, 1.2 and 1.8 V

• Low Temperature Drift Coefficient on the Output Voltage

• Low Quiescent of 0.1 mA

• Fold Back Protection Circuit

• These are Pb−Free Devices

Typical Applications

• Portable Equipment

• Hand−Held Instrumentation

• Camcorders and Cameras
