The 8 mA quiescent current is typical for a 1 A-class linear regulator; the 800 µA maximum supply current covers the control circuitry and does not add significantly to the thermal budget. ## ROHS3 compliance — EU regulatory acceptance ROHS3 compliant, with no exemptions for phthalates or lead in solder — the part ships in tape-and-reel or cut-tape format for through-hole assembly.","metaTitle":"ROHM BA7812CP-E2 12V 1A LDO, TO-220CP-3, Active","metaDescription":"ROHM BA7812CP-E2 fixed 12V 1A linear regulator, 63dB PSRR at 120Hz, TO-220CP-3, -40°C to 85°C.
