High Current, High Accuracy LDO from Diodes Incorporated Addresses Noise-Sensitive Power Conversion Applications

Diodes Incorporated (Diodes) (Nasdaq: DIOD) has released a 3A-rated low-dropout (LDO) voltage regulator supporting 4.4µVRMSoperation (at 0.8V output). Delivering a clean supply, theAP7179Dis highly optimized for powering noise-sensitive components - such as the high-performance SerDes, RF components, and data converters needed for high-speed communications, test and measurement, medical, and video applications. Remote radio units (RRUs), outdoor backhaul units, mMIMO active antenna systems, ultrasound scanners, radar systems, and lab/field instrumentation are among the types of hardware into which it can be incorporated.

The AP7179D has a ±1% output accuracy across line, load, and temperature. This device’s 180mV (maximum) dropout voltage at a 3A load current supports a wide voltage conversion range. Its low-noise reference and error amplifier enables a minimal noise floor. In addition, its 40dB power supply rejection ratio (PSRR) at 500kHz substantially lowers the coupling of input supply noise to the output.

There are two output voltage selection modes for this LDO: pin-programmable between 0.8V and 3.95V, or adjustable using an external resistor divider from 0.8V to 5.5V. The resulting flexibility significantly reduces the number of accompanying components needed.

The device’s low output noise mitigates both power-supply-generated phase noise and clock jitter. Because of this, alongside its high-current capabilities, this device is compatible with high-performance processors, such as FPGAs, ASICs, and DSPs.

DIODES公司的高电流、高精度LDO解决了对噪声敏感的功率转换应用
DIODES百利通亚陶晶振公司(DIODES)(纳斯达克代码:DIOD)发布了3A额定低压差(LDO)稳压器支持4.4V皇家邮轮操作(0.8V输出时)。提供清洁的供应AP7179D针对为噪声敏感器件供电进行了高度优化,例如高速通信、测试和测量、医疗和视频应用所需的高性能SerDes、RF器件和数据转换器。远程无线电单元(rru)、室外回程单元、mMIMO有源天线系统、超声波扫描仪、雷达系统和实验室/现场仪器仪表都是它可以集成的硬件类型。

AP7179D石英晶体振荡器在整个线路、负载和温度范围内具有1%的输出精度。该器件在3A负载电流下的180mV(最大)压差支持宽电压转换范围。其低噪声基准电压源和误差放大器可实现最低的噪底。此外,它在500kHz时的40dB电源抑制比(PSRR)大大降低了输入电源噪声与输出的耦合。

该LDO有两种输出电压选择模式:0.8V至3.95V之间的引脚可编程,或使用外部电阻分压器在0.8V至5.5V范围内可调。由此带来的灵活性显著减少了所需的配套元件数量。

该器件的低输出噪声减轻了电源产生的相位噪声和时钟抖动。因此,除了高电流能力之外,该器件还兼容高性能处理器,如FPGAs、ASICs和DSP。
