【选型】日清纺LDO RP110N281D-TR-FE用于灯具开发，输出电流150mA
在灯具产品设计当中需要一颗输入3V~4V，输出电压2.8V，输出电流大于120mA的LDO，在这里选用了日清纺的RP110N281D-TR-FE，该LDO输入电压1.4V~5.25V，输出电压2.8V，输出电流为150mA，参数条件满足在该项目中的设计要求。
以下是该LDO的参数表：
从以上可知：
RP110N281D-TR-FE的输入电压为1.4V~5.25V，输入电压范围大，基本涵盖5V以下；
输出电压为2.8V；
输出电流为150mA；
静态功耗在1μA以内，静态功耗低，适用于低功耗设计；
工作温度为-40℃~85℃。
以上是RP110N281D-TR-FE的典型运用电路，外围电路简单就两颗电容，增加了使能脚做关断，可以运用于更多使用场景。
综上所述，以上是RP110N281D-TR-FE的性能参数，完全能满足在灯具项目中的开发，而且该LDO增加有使能脚，使用会更加灵活。
