关于示例中使用的线性稳压器IC
・为了便于说明,在示例中我们将使用非常受欢迎的线性稳压器IC“BA1117”。
BA1117是浮动工作的、输出可调的低饱和(低压差)稳压器IC,属于LDO。下面是主要规格和框图。从结构上看,浮动工作型线性稳压器没有接地(GND)引脚。
图 1
实现电源时序②的工作波形如下所示。
・输入额定电压:15V
・输入电压范围:VOUT+1.4V~10V
・参考电压:1.25V
・输出电压设置范围:1.25V~8.6V
・输出电流:1A
・压差电压:1.2V(1A时)
・输出电压精度:±1%(不包括外置电阻的精度)
・输出电流:5mA *1~1A
・工作结温范围:-20℃~+105℃
*1: 含电压设置电阻的电流
*关于规格值,请查阅最新版的技术规格书。
BA1117是在输出级使用了NPN型晶体管的LDO,压差电压(可动作的输入输出电压差。后续将详细介绍)为1.2V左右。在输出级使用了PNP型晶体管或MOSFET的LDO,其压差电压仅为0.5V左右,所以可能有人会有疑问:“1.2V是LDO吗?”由于标准型(78xx等)的压差电压有2V左右,因此BA1117被归类为LDO。
在阅读本系列文章时,请注意以下两点:在解释说明的过程中,会出现“压差电压1.2V”这样的规格值,但这不一定表示这是保证值(最大值或最小值)。因此,在您实际设计时,请务必查阅最新版的技术规格书。另外,在电路示例中,电路图可能会省略掉一部分电路,因此,请仅作为参考使用。

【经验】LDO线性稳压器的并联之使用二极管并联LDO
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。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VF的量,因此需要采取在LDO的输出电压设置中添加VF部分等相应的对策。

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。
