NCP582
Low Noise 150 mA CMOS
LDO Regulator with Enable
The NCP582 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 and are offered in active
low and active high with auto discharge.
The following ceramic capacitors are the recommended values to
be used with these devices; for V_out < 2.5 V, C_in = C_out = 1.0 mF,
V_out w 2.5 V, C_in = C_out = 0.47 mF.
Features
• Ultra−Low Dropout Voltage of 220 mV at 150 mA
• Low Output Noise of 30 mVrms
• Excellent Line and Load Regulation
• High Output Voltage Accuracy of "2%
• Low Supply Current of 75 mA
• Excellent Power Supply Rejection Ratio
• Wide Operating Voltage of 1.5 V to 3.3 V
• Low Quiescent Current of 0.1 mA
• Fast Dynamic Performance
• Fold Back Protection Circuit
• Low Temperature Drift Coefficient on the Output Voltage
• These are Pb−Free Devices
Typical Applications
• Portable Equipment
• Hand−Held Instrumentation
• Camcorders and Cameras
