NCP590

Dual Output, High Accuracy,

Ultra Low Dropout

CMOS LDO

The NCP590 is a family of very high precision dual-output CMOS

LDOs offered in a 2x2 DFN8 package. Each output is capable of

delivering up to 300 mA and is available in voltages from 0.8 V to

5 V.

The set point output voltage is accurate to within

±0.9% with an

operating voltage input up to 5.5 V. With its ultra low dropout

characteristics and low quiescent and ground current consumption,

the NCP590 is ideal for all battery operated consumer and

microprocessor applications. The NCP590 is protected against short

circuit and thermal overload conditions.

Features

• Dual Outputs, Each Supporting up to 300 mA Current

• Available in Output Combinations Ranging from 0.8 V to 5.0 V

• 2.1 V to 5.5 V VCC Operating Supply Range

• Ultra-High Accuracy (0.9% max at 100 mA load & 25°C)

• Each Output has a Dedicated Enable Control Pin

• Enable Threshold Supports sub-1 V Systems

• Very Low Drop Out Voltage (50 mV typ @ 100 mA load)

• Low Noise (~20 mVrms) without Bypass Capacitor

• Ultra Low Shutdown Current (0.2 mA)

• Low Quiescent and Ground Current (80 - 100 mA typ.)

• Thermal Shutdown and Current Limit Protection

• Active Output Discharge when Disabled

• No Minimum Output Current Required for Stability

• Requires Cout of only 1.0 mF (any ESR) for Stability

• Stable with Any Type of Capacitor (including MLCC) and Zero Load

• Input Under Voltage Lock Out (UVLO)

• Internally Compensated Regulator for Quick Transient Response

• Space-Ef ficient 2x2 DFN8 Package

• This is a Pb-Free Device

Applications

• Cellular Phones

• Cameras

• MP3/CD Players, PDA's, Camcorders

• DSP Supplies

• Portable Info-tronics

• PCMCIA Cards

• Networking Systems, DSL/Cable Modems
