EUP7230
Dual, Low-Noise, High-PSRR,
300mA LDO without Bypass Capacitor
DESCRIPTION
The EUP7230 is a dual-channel low noise, low
dropout. High PSRR, high accuracy CMOS voltage
regulator. Performance features include low output
noise, high ripple rejection ratio, low dropout and
very fast turn-on times.
The EUP7230 is also fully compatible with low ESR
ceramic capacitors, reducing cost and improving
output stability. This high level of output stability is
maintained even during frequent load fluctuations,
due to the excellent transient response performance
and high PSRR achieved across a broad range of
frequencies.
The EN function allows the output of each regulator
to be turned off independently, resulting in greatly
reduced power consumption. The EUP7230 is
available in small 1.6mm×1.6mm TDFN-6 and
TSOT23-6 packages.
