LOW NOISE DUAL 300mA LDO
DESCRIPTION
The UTC LR7XXYY series are highly accurate, Dual, low noise,
CMOS LDO voltage regulators. Performance features of the series
includes low output noise, high ripple rejection ratio, low dropout
and very fast turn-on times.
The UTC LR7XXYY includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators internally. The LR7XXYY current limiters' foldback
circuit also operates as a short protect for the output current limiter.
The UTC LR7XXYY series 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 output voltage of these ICs is internally fixed with
high accuracy (1%). |
