【应用】国产可编程基准源RS431AYSF3用于变频器降压电路，电压精度0.5%

【应用】国产三端可调稳压器用于电源模块，基准电压容差0.5%，等效全量程温度系数为50ppm/℃

某客户在做一款DC-DC电源模块产品，要求选用一款2.5V的三端可调稳压器，用于电压输出电路上起到稳压反馈的作用；润石科技推出的一款用于副边电流反馈电路上的三端可调稳压器RS431AYSF3，可满足此类产品的应用需求。

【应用】国产精密稳压源RS431AYSF3助力砖块电源设计，具有0.5%参考电压精度，灌电流能力低至0.5mA

砖块电源由于体积小、功率小等原因。一般使用反激拓扑较多。其副边电流反馈一般使用可控精密稳压源431加光耦的电路搭配。现介绍润石科技的一款用于副边电流反馈的精密稳压源RS431AYSF3，具有0.5%参考电压精度，低至0.5mA的灌电流能力。

【应用】国产基准源芯片RS431AYSF3用于智能电力仪表，温漂50ppm/℃，电压精度0.5%

智能电力仪表可保障整个系统安全可靠运行。本文根据客户的设计需求，推荐润石的基准源芯片RS431AYSF3，可实现全温范围能的温漂在50ppm/℃，电压精度0.5%，在保证精度的同时能达到温漂的要求，保证采集数据精准。

【选型】Pin-to-Pin替换TL431AIDBZR的国产基准源RS431AYSF3，具有0.5%更高参考电压精度

在反激式开关电源电路中，输出稳压反馈电路设计通常会使用基准源TL431 和光耦PC817来配合使用,某客户选用了TI的TL431AIDBZR，由于受中美贸易战影响，交期和价格都得不到保证，急需国产替代型号，本文重点推荐润石科技的RS431AYSF3，可Pin-to-Pin替代。

【产品】三端可调并联稳压器RS431和RS432，输出电压最高可调至36V

润石科技推出的RS431和RS432三端可调并联稳压器在适用的温度范围内具有热稳定性，可通过两个外部电阻将输出电压设置为从VREF（约2.5V）至36V范围内的任意值。它们具有非常灵敏的启动特性，因此能在许多应用中完美替代齐纳二极管。RS431和RS432均有两个等级，A级和B级的初始容差（在25℃下）分别为0.5%和1%。
