本文是ROHM“LDO 线性稳压器的并联”系列文章中的一篇，讲述如何使用二极管并联LDO。

首先来看通过二极管并联LDO的电路图。采用二极管并联LDO连接方法，由于输出路径中有二极管，因此输出电压仅下降二极管正向电压（以下简称“V_F”）的量。所以，要想得到预期的输出电压，需要采取诸如将二极管V_F添加到LDO的输出电压设置值中等措施。另外，每个二极管的V_F会有个体波动，而且还会因负载电流和温度而异，因此，无法期待精确的输出电压精度。

通过二极管连接两个LDO输出时的电路

这个电路也是由输出电压高的LDO供给电流，但由于流过的电流因二极管的V_F而异，因此可以在一定程度上吸收两个LDO之间的电压差。输出电压的平衡关系可以通过以下公式来表示：

V_OUT1－V_{F1（IOUT1）}＝V_OUT2－V_{F2（IOUT2）}

V_OUT1：LDO1的输出电压
V_OUT2：LDO2的输出电压
VV_{F1（IOUT1）}：I_OUT1的D1的V_F
V_{F2（IOUT2）}：I_OUT2的D2的V_F

例如，从下图中可以看出使用3.3V、1A输出的LDO，且LDO1的输出电压比LDO2高1%时，各LDO供给负载的输出电流是如何分配的。在负载电流为1A的节点，即使LDO的输出电压差仅为1%，但电流分配却有很大差异：LDO1为0.64A，LDO2为0.36A。

输出电压差为1%时的输出电流分配

接下来，下图给出了两个LDO间的输出电压差对输出电流的影响。

下图表示LDO1比LDO2的输出电压高时各LDO的输出电流之比。当两个LDO的输出电压完全相同时，输出电流的比率为50%（平均分配输出电流），但随着输出电压差的增加，电流比率的差也会随之增加。例如假设LDO1的输出电压波动＋1%、LDO2的输出电压波动－1%，则LDO1的电流输出为77%、LDO2的电流输出为23%，电流分配很不平衡。

输出电压差对输出电流比率的影响

从下图可以看出当使用最大推荐输出电流值为1A的LDO时，LDO间的输出电压差对LDO并联电路的输出电流的影响。

如果LDO之间完全没有电压差，则两个LDO的输出电流相等，因此可以输出2A（1A+1A）的电流。但随着LDO输出电压差的增加，能够输出的电流值越来越小。在LDO1的输出电压波动＋1%、LDO2的输出电压波动－1%的条件下，使用最大推荐输出电流值为1A的LDO时，当两个LDO中的一个达到1A时该LDO将达到最大输出状态，因此相对于2A的输出电流能力，最多只能输出1.37A的电流。

输出电压差对最大输出电流的影响

最后请看负载调节图表。

负载调节

与LDO输出相比，输出电压下降了二极管V_F的量，并且二极管V_F随负载电流的增加而增加，因此输出电压进一步降低。除了各LDO本来就有的负载调节器之外，二极管VF的影响也很大，而且输出电压的变化也很大，因此，如前所述，负载调节器并不理想。

关键要点:

・在使用二极管进行LDO并联的方法中，由于输出路径中有二极管，因此输出电压会下降二极管V_F的量，因此需要采取在LDO的输出电压设置中添加V_F部分等相应的对策。

・每个二极管的V_F存在个体差异，而且还会因负载电流和温度而异，因此，无法期待精确的输出电压精度（负载调节器）。

・尽管使用二极管可以缓和输出电压差的问题，但无论如何，由于两个LDO的输出电压存在压差，各LDO的输出电流分配还是具有很大波动。

【经验】LDO线性稳压器的并联之使用镇流电阻并联LDO的方法

本文是ROHM系列文章“LDO线性稳压器的并联”中的一篇，介绍使用镇流电阻并联LDO的方法。使用镇流电阻并联LDO的方法中，输出电流可按计算公式求出的值分配。由于LDO的输出电流会流过镇流电阻，因此在负载点会产生电压降，电阻中会产生功率损耗。

关于线性稳压器，请告知功耗损失的计算方法。

线性稳压器的功耗损失Pd为，如设成Vin：电源电压、Vo：输出电压、Io：输出电流、Icc：电路（偏置）电流，则 Pd=（Vin-Vo）×Io+Vin×Icc

关于线性稳压器，请告知过流保护(OCP)的动作。

超过建议输出电流时，通过为各产品设置的过电流检测值进行电流限制。在过流保护启动后，电流折返电路也会启动，在降低输出电压的同时限制输出电流，从而保护IC以免破坏。大多数线性稳压器，过电流消失后，输出电压会自动恢复，但也有锁存的类型，因此请确认Datasheet。
