EUP7201
Dual ,Low-Noise,150mA LDO Regulator
DESCRIPTION
The EUP7201 is highly accurate, Dual, low noise, CMOS
LDO voltage regulator. Performance features include low
output noise, high ripple rejection ratio, low dropout and
very fast turn-on times.
The EUP7201 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 EUP7201 is available in the
SOT23-6 , TDFN-6 and USP-6 package.
