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 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 mA (LP mode, Output Voltage ≤ 1.5 V)
40 mA (FT mode)
• Excellent Power Supply Rejection Ratio
• Low Temperature Drift Coefficient on the Output Voltage
• Low Quiescent Current of 0.1 mA
• This is a Pb−Free Device*

APPLICATION INFORMATION
Input Decoupling
A 1.0 mF tantalum capacitor is the recommended value
to be connected between Vin and GND. For PCB layout
considerations, the traces of Vin and GND should be
sufficiently wide in order to minimize noise and prevent
unstable operation.
Output Decoupling
It is recommended to use a 2.2 mF or higher tantalum
capacitor on the Vout pin. For better performance, select a
capacitor with low Equivalent Series Resistance (ESR).
For PCB layout considerations, place the output capacitor
close to the output pin and keep the leads short as possible.
