BD800M5WFPJ-C (开发中)
车载用500mA可变输出LDO稳压器

BD800M5Wxxx-C是低功耗电流线性稳压器,适合蓄电池直连的车载系统。本IC的规格为45V耐压、输出电流500mA、消耗电流17µA。输出电压精度:BD800M5WFPJ-C、BD800M5WHFP-C为±2%、BD800M5WFP2-C为±2.5%(不包括反馈电阻的精度。)。通过在ADJ端子上连接电阻,可在1.2V~16V的范围内设置输出电压。具备输出关断功能,在向EN端子施加HIGH电压时,IC输出ON。施加LOW电压时,输出OFF。本IC内置防止因输出短路等发生IC破坏的过流保护电路、以及防止因过负荷状态等使IC发生热破坏的过热保护电路。输出相位补偿电容器可使用低ESR的陶瓷电容器。
