EUP7230-双路,低噪声,高电源抑制比,300mA无旁路电容的线性稳压器  DataSheet
概述
EUP7230是一款双路、低噪声、低漏失、高PSRR、高精度的CMOS线性稳压器。其特性包括低输出噪声，高电源抑制比，低漏失电压及快速启动。
EUP7230还和低ESR的陶瓷电容完全兼容，降低了成本并增强了输出稳定性。这种高的输出稳定性即使在频繁的负载波动时仍然能够保持，这得益于芯片在很宽的频率范围内具有良好的瞬态响应特性和高的电源抑制比特性。
EN功能允许每一路稳压器单独的关断，极大的降低了功率的消耗。EUP7230有1.6mm×1.6mm TDFN-6 、TSOT23-6和SOP-8(EP)封装。

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.
