LR7XXYY数据手册UTC中文资料规格书

描述 Description

The UTC LR7XXYY series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance

特性 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%).
