1 A, 1% Precision Very Low
Dropout Voltage Regulator
with Enable and Active
Discharge
The NCP706A is a Very Low Dropout Regulator which provides up
to 1 A of load current and maintains excellent output voltage accuracy
of 1% 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 3.0 V fixed output voltage
option. NCP706A is fully protected against overheating and output
short circuit.
Very small 8−pin XDFN8 1.6 x 1.2, 04P package makes the device
especially suitable for space constrained portable applications such as
tablets and smartphones. Parts feature active output discharge
function.
Features
• Operating Input Voltage Range: 2.4 V to 5.5 V
• Fixed Output Voltage Option: 3.0 V
Other Output Voltage Options Available on Request.
• Low Quiescent Current of Typ. 200 mA
• Very Low Dropout: 155 mV Max. at IOUT = 1 A
• ±1% Accuracy Over Load/Line/Temperature
• High PSRR: 60 dB at 1 kHz
• Internal Soft−Start to Limit the Inrush Current
• Thermal Shutdown and Current Limit Protections
• Stable with a 1.0 mF Ceramic Output Capacitor
• Available in XDFN8 1.6 x 1.2, 04P 8−pin Package
• Active Output Discharge
• These are Pb−Free Devices
Typical Applications
• Tablets, Smartphones,
• Wireless Handsets, Portable Media Players
• Portable Medical Equipment
• Other Battery Powered Applications
