The DPAK (TO-252) package's exposed tab carries the thermal dissipation; at 800 mA and a 6.5 V input, the die dissipates about 1.2 W — the tab's copper area on the PCB sets the junction temperature below the 125°C maximum. STMicroelectronics lists the LD1117DT50TR as Active. ROHS3 compliant.","metaTitle":"LD1117DT50TR – STMicro 5V 800mA LDO, DPAK, Active","metaDescription":"STMicroelectronics LD1117DT50TR fixed 5V output LDO, 800mA, 1.2V dropout max, 75dB PSRR at 120Hz.
