NCP571/D

NCP571, NCV571

150 mA CMOS Low Iq Low

Output Voltage Regulator

The NCP571 series of fixed output low dropout linear regulators are

designed for handheld communication equipment and portable battery

powered applications which require low quiescent current. The

NCP571 series features an ultra−low quiescent current of 4.0

mA.

Each device contains a voltage reference unit, an error amplifier, a

PMOS power transistor, resistors for setting output voltage, current

limit, and temperature limit protection circuits.

The NCP571 has been designed to be used with low cost ceramic

capacitors and requires a minimum output capacitor of 0.1

mF. The

device is housed in the TSOP−5 or DFN6 surface mount package.

Standard voltage versions are 0.8 V, 0.9 V, 1.0 V and 1.2 V.

Features

• Low Quiescent Current of 4.0 mA Typical

• Maximum Operating Voltage of 12 V

• Low Output Voltage Option down to 0.8 V

• High Accuracy Output Voltage of 3.0%

• Industrial Temperature Range of −40°C to +85°C

(NCV571, TA = −40

°C to +125°C)

• NCV Prefix for Automotive and Other Applications Requiring

Unique Site and Control Change Requirements; AEC−Q100

Qualified and PPAP Capable

• These are Pb−Free Devices
