• ADP130 minimum input voltage

    Hai,

    I am using ADP130 fixed 1.2V gen LDO in my design and wanted to know whether it can be operated from a 1.5V input supply or not? Current drawn will be 210mA maximum. In datasheet it mentioned that input supply should be Vout+0.4V. Let me know you…

  • ADP130: Does the datasheet undervoltage lockout spec apply to Vin or Vbias?

    The datasheet states:

    UNDERVOLTAGE LOCKOUT
    The ADP130 has an internal undervoltage lockout circuit that
    disables all inputs and the output when the input voltage is less
    than approximately 2.1 V. This ensures that the ADP130 inputs

    Hi,

    I apologize for this oversight. The LDO in question should be ADP130 or ADP171. Please see link to understand how you can reduce the power delivery network.

  • RE: LDO用于数字负载、模拟负载以及射频负载需要关注哪些指标?

    LDO用于模拟和射频负载: 像ADP121和ADP130具有的低噪声和高电源抑制(PSR)性能对模拟环境中使用的LDO来说非常重要,因为模拟器件比数字器件对噪声更敏感。模拟LDO需求的主要来自无线接口要求——不损伤接收器或发送器,并在音频系统中不产生爆破音或嗡嗡声。无线连接非常容易受噪声的影响,如果噪声干扰到信号,接收器的效果将大打折扣。在考虑模拟线性稳压器时,器件要能抑制来自上游电源和下游负载的噪声,而且自身不增加噪声,这一点很重要。
