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.
