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.","metaTitle":"ROHM BA7806CP-E2 Linear Regulator, 6V Fixed, 1A, TO-220CP-3","metaDescription":"Active ROHM BA7806CP-E2 linear regulator, fixed 6V output at 1A. 73dB PSRR at 120Hz, 2V dropout, industrial temp range.

That is the ripple-rejection figure at the fundamental frequency of a full-wave rectified 60 Hz line (or 100 Hz for 50 Hz mains). A 73 dB rejection means a 1 V peak-to-peak ripple on the input becomes roughly 0.22 mV at the output — clean enough to power a 16-bit ADC reference or a low-noise op-amp front end without additional post-filtering."},{"question":"What compliance documentation does ROHM Semiconductor provide for BA7806CP-?","answer":"The part is ROHS3 Compliant.
