MC7805BDTRKG

MC7805BDTRKG is the tape-and-reel DPAK ordering code for the onsemi MC7805B 5 V linear regulator, written word-for-word in the ordering table of the maker’s MC7800/D datasheet (Rev. 15): DPAK body, 2,500 pieces per tape and reel, lead-free, with the B grade fixing a junction range of -40 °C to +125 °C. Read on the B-grade column, its output is 5.0 V typical, held between 4.8 V and 5.2 V at 25 °C, its bias current is 3.2 mA typical and 8.0 mA maximum, its ripple rejection is 68 dB typical at 120 Hz, its dropout voltage is 2.0 V typical at 1.0 A, its peak current is 2.2 A typical, and its maximum input voltage is 35 Vdc. onsemi publishes no per-code lifecycle field in this document; what can be stated from the maker’s own material is that the current Rev. 15 manual carries this exact order code in its table and no discontinuation notice accompanies it. The selection point is the 7805 socket in surface-mount form: legacy industrial and consumer boards keep their 5 V rail and their layout while moving assembly to reflow, with the tab available as a heatsink path. Selection advice: dropout on the 78xx class is two volts at load, so confirm the unregulated input keeps that headroom at worst-case line and load before treating this as a drop-in for a linear-supply rail. Parameters verified against the onsemi MC7800/D datasheet Rev. 15 (ordering table and the B-grade electrical column).
