MC7806BD2TG

MC7806BD2TG Description

The MC7806BD2TG from onsemi is a fixed-output 6V, 1A linear voltage regulator in a D2PAK (TO-263-3) surface-mount package. Designed for robust performance, it accepts input voltages up to 35V and delivers a stable 6V output with a typical dropout voltage of 2V @ 1A. This regulator features over-temperature and short-circuit protection, ensuring reliable operation in demanding environments. With a quiescent current of 8 mA and 65dB PSRR (120Hz), it minimizes power loss and noise, making it suitable for precision applications. Though marked obsolete, it remains a dependable choice for legacy designs requiring high-current, low-noise regulation.
