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 quiescent 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, in fixed output voltages between 0.8 V and 3.3 V.

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

• Tri−mode Operation

• Low Dropout Voltage:

Typ 550 mV at 300 mA, Output Voltage = 0.9 V

Typ 480 mV at 300 mA, Output Voltage = 1.0 V

Typ 310 mV at 300 mA, Output Voltage = 1.5 V

• Excellent Line Regulation of 0.01%/V (0.05%/V LP Mode)

• Excellent Load Regulation of 15 mV (40 mV FT Mode)

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

• Ultra−Low Iq 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)

• Very Low Shutdown Current of 0.1 mA

• Excellent Power Supply Rejection Ratio of 70 dB at f = 1.0 kHz

• Low Temperature Drift Coefficient on the Output Voltage of

"100 ppm/°C

• Fold Back Protection Circuit

• Input Voltage up to 6.5 V

• These are Pb−Free Devices

Typical Applications

• Portable Equipment

• Hand−Held Instrumentation

• Camcorders and Cameras
