Hi Orlando,
Switching power supply noise typically spans a frequency range of 300KHz and up. The LDO after the switcher is helpful in attenuating the lower frequency noise, and you can still get decent rejection up to about 1MHz. Take a look at the ADP7158…
Hi,
The currents that is used in calculation, includes all output drivers and all features when set to maximum current consuming condition and all PVT variations and also aging factor. For a typical configuration (some outputs are pulsed, analog delay…
1）低压差稳压器(LDO)系列——ADP715x
该系列产品具有超低噪声性能，可消除系统干扰噪声，并改善接收器、发送器和音频质量。ADP715x LDO的目标应用包括：无线基站、有线通信、工业仪器仪表、高端音频设备和医疗设备。 这些最新的LDO能为噪声敏感型精密模拟和RF应用——尤其是需要更高的数据速率时——提供更干净的供电轨、更快的瞬态响应和更高的电源电压抑制比(PSRR)。
ADP715x LDO支持的噪声敏感型应用数量不断扩大，囊括了RF收发器、压控振荡器、锁相环频率合成器、时钟和高速ADC…
