CMOS IC

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.

SOP-8

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%).
