Active production — what it means for the BOM line
The BA7806CP-E2: For a procurement desk managing a multi-year production run, this part is a stable line item that does not force a respin or a substitute qualification.
The headline ratings that decide fit
Fixed 6 V output at 1 A continuous — this is the load current the regulator can deliver without dropping out of regulation. 73 dB PSRR at 120 Hz tells you how well the regulator rejects ripple from a full-wave rectified line — a 120 Hz hum on the input gets attenuated by a factor of ~4500. This matters when the regulator feeds analog circuitry (op-amp rails, ADC references) where power-supply ripple couples into the signal path. Quiescent current sits at 8 mA — not a micropower LDO, but reasonable for a 1 A fixed regulator in always-on industrial or audio equipment where the regulator's own draw is a small fraction of the load.
Thermal and protection — the real-world operating envelope
The TO-220CP-3 package with cropped leads is the through-hole variant — the tab is the thermal path, so the heatsink interface matters more than the plastic body. Built-in over-current and over-temperature protection means the regulator folds back or shuts down before the die reaches destructive temperature — useful when the load side has an intermittent short or the ambient temperature spikes during a cooling fan failure.
Package note — the cropped-lead TO-220
The TO-220-3 Cropped Leads (also called TO-220CP-3) has the leads trimmed shorter than a standard TO-220 — verify the PCB hole pattern and the mating connector or socket. The standard TO-220 footprint may still accept it, but the lead protrusion below the board will be less, which can affect wave-solder fillet formation.
