1 A, 1% Precision Very Low

Dropout Voltage Regulator

with Enable

The NCP708 is a Very Low Dropout Regulator which provides up to

1 A of load current and maintains excellent output voltage accuracy of

1.5% including line, load and temperature variations. The operating

input voltage range from 2.4 V up to 5.5 V makes this device suitable

for Li−ion battery powered products as well as post−regulation

applications. The product is available in 3.3 V fixed output voltage

option. Other voltage options are possible on request. NCP708 is fully

protected against overheating and output short circuit.

Small 6−pin UDFN6 3x3 package makes the device especially

suitable for space constrained applications.

Features

• Operating Input Voltage Range: 2.4 V to 5.5 V

• Fixed Output Voltage Option: 3.3 V

Other Output Voltage Options Available on Request.

• Low Quiescent Current of Typ. 200 mA

• Very Low Dropout: 250 mV Max. at IOUT = 1 A

• ±1.5% Accuracy Over Load/Line/Temperature

• High PSRR: 70 dB at 1 kHz

• Internal Soft−Start to Limit the Inrush Current

• Thermal Shutdown and Current Limit Protections

• Stable with a 4.7 mF Ceramic Output Capacitor

• Available in UDFN6 3x3 mm Package

• These are Pb−Free Devices

Typical Applications

• Hard−Drives, SSDs

• Servers, Networking Equipment

• Telecom Equipment

• Battery Powered Applications
