ME6212系列高精度、高紋波抑制比、低噪聲、超快響應(yīng)線性穩(wěn)壓器
概述
ME6212系列是以CMOS工藝制造的高精度,高紋波抑制比,低噪音,超快響應(yīng)低壓差線性穩(wěn)壓器。ME6212系列穩(wěn)壓器內(nèi)置固定的參考電壓源,誤差修正電路,限流電路,相位補償電路以及低內(nèi)阻的 MOSFET,達(dá)到高紋波抑制,低輸出噪音,超快響應(yīng)低壓差的性能。
ME6212 系列兼容體積比鉭電容更小的陶瓷電容,而且不需使用 0.1μF 的 By-pass 電容,更能節(jié)省空間。
ME6212 系列的高速響應(yīng)特性能應(yīng)付負(fù)載電流的波動,所以特別適合使用于手持及射頻產(chǎn)品上。通過控制芯片上的 CE 腳可將輸出關(guān)斷,在關(guān)斷后的功耗只有1μA以下。

ME6212 Series High Speed LDO Regulators, High PSRR, Low noise,
General Debion
l The ME6212 series are highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the l l ME6212 series is ideal for today’s cutting edge mobile phone. Internally the ME6212 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The ME6212’s current limiters' foldback circuit also operates as a short protect for the output current limiter and. the output pin. The ME6212 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 perbance and high PSRR achieved across a broad range of frequencies.The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption.
