800mA低压差线性调压器LM1117/LM1117I
LM1117 是一个低压差电压调节器系列。其压差在1.2V输出，负载电流为800mA时为1.2V。它与国家半导体的工业标准器件LM317有相同的管脚排列。LM1117 有可调电压的版本，通过2个外部电阻可实现1.25～13.8V输出电压范围。另外还有5个固定电压输出（1.8V、2.5V、2.85V、3.3V和5V）的型号。
LM1117 提供电流限制和热保护。电路包含1个齐纳调节的带隙参考电压以确保输出电压的精度在±1%以内。LM1117 系列具有LLP、TO-263、SOT-223、TO-220和TO-252 D-PAK封装。输出端需要一个至少10uF的钽电容来改善瞬态响应和稳定性。
