Product Preview
3−Mode 200 mA LDO
Regulator
The NCP584 series of low drop out 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 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
• Low Dropout Voltage of 300 mV at 200 mA, Output Voltage = 1.0 V
200 mV at 200 mA, Output Voltage = 1.5 V
140 mV at 200 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 A (LP mode, Output Voltage ≤ 1.5 V)
40 A (FT mode)
• Excellent Power Supply Rejection Ratio
• Low Temperature Drift Coefficient on the Output Voltage
Typical Applications
• Portable Equipment
• Hand−Held Instrumentation
• Camcorders and Cameras

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
