NCP582
Ultra-Fast, 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 quiescent 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 without Noise Reduction Cap
• Excellent Line Regulation of 0.02%/V
• Excellent Load Regulation of 22 mV
• High Output Voltage Accuracy of "2%
• Low Iq Current of 75 mA
• Very Low Shutdown Current
• Excellent Power Supply Rejection Ratio of 70 dB at f = 1.0 kHz
• Wide Output Voltage Range of 1.5 V to 3.3 V
• Fast Dynamic Performance
• Fold Back Protection Circuit
• Low Temperature Drift Coefficient on the Output Voltage of
"100 ppm/°C
• Input Voltage up to 6.5 V
• These are Pb−Free Devices
Typical Applications
• Portable Equipment
• Hand−Held Instrumentation
• Camcorders and Cameras
