The fixed 8.5 V output at 500 mA with a maximum dropout of 0.7 V at full load means the input rail must stay above 9.2 V to maintain regulation; below that the output falls out of spec. Input voltage is rated up to 16 V, giving headroom for unregulated supplies or 12 V rails with tolerance. ## Package and thermal — TO-252-5 PPAK board-fit Enable control and protection features (over-current and over-temperature) are integrated, so no external supervisor is needed for basic fault handling.","metaTitle":"STMicro LF85CPT-TR LDO, 8.5V Fixed, 500mA, PPAK","metaDescription":"STMicroelectronics LF85CPT-TR linear regulator, 8.5V fixed output, 500mA, PSRR 72dB~57dB, TO-252-5 PPAK, -40 to 125°C.
