Frequently Asked Questions
LMS8117AMP-3.3/NOPB 的输出电压和最大输出电流是多少？
该器件固定输出 3.3V，最大持续输出电流为 800mA，压差典型值 1.15V（满载），适合为 MCU、FPGA 和无线模块供电。
LMS8117AMP-3.3/NOPB 与 LM1117-3.3 有何区别，可以替换吗？
LMS8117AMP-3.3/NOPB 是 LM1117-3.3 的增强版本，输入电压范围更宽（最高 15V），工作温度上限达 125°C，封装尺寸兼容 SOT-223，可直接 pin-to-pin 替换。
SOT-223 封装散热如何处理，PCB 布局有什么注意事项？
建议在 SOT-223 散热焊盘下方铺铜并打散热过孔，将热阻降至约 40°C/W。器件内置过温保护，结温超过 165°C 自动关断，冷却后自动恢复。输入输出端各加 10µF 旁路电容可提升稳定性。
该型号是否符合 RoHS 和无铅要求？
是的，后缀 /NOPB 表示无铅（No Lead/Pb-Free），完全符合 RoHS 2011/65/EU 指令，适用于欧盟及全球环保合规项目。
最小起订量（MOQ）和交货周期是多少？
现货库存支持 1 件起购，阶梯价格从 $2.10（1件）到 $0.54（5000件+）。标准交货周期为 3–7 个工作日，大批量订单请联系询价获取最新库存和排期。
