NCP584
Tri-Mode 200 mA CMOS
LDO Regulator with Enable
The NCP584 series of low drop out 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 package.
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 of 400 mV at 200 mA, Output Voltage = 0.9 V
300 mV at 200 mA, Output Voltage = 1.2 V
200 mV at 200 mA, Output Voltage = 1.8 V
• Excellent Line Regulation of 0.05%/V (0.10% LP Mode)
• Excellent Load Regulation of 10 mV (20 mV FT Mode)
• High Output Voltage Accuracy of ±2% (±3% LP mode)
• Ultra−Low Iq Current of:
3.5 mA (LP mode, Output Voltage ≤ 1.5 V)
40 mA (FT mode)
• Very Low Shutdown Current of 0.1 mA
• Excellent Power Supply Rejection Ratio of 75 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
