- DESCRIPTION
- The AIC1747B is a 300mA, low-dropout (LDO)
linear regulator with fast transient response and
high PSRR. It offers high output accuracy, low
dropout voltage and low quiescent current as well
as fast start-up time. This regulator is based on a
CMOS process.
The AIC1747B is designed to work with low-ESR
ceramic capacitors, reducing the amount of the
PCB area necessary for power applications. Only
a 1uF ceramic output capacitor can make the
device stable over the whole load range current
(0mA to 300mA).
The other key features of AIC1747B include overcurrent
protection and thermal shutdown. The
AIC1747B is packaged in DFN-4 (1x1) package.
