The output voltage is set with an external resistor divider from a 1.225 V reference to a maximum of 25 V, matching the input voltage ceiling. Housed in a TO-220-5 Full Pack (TO-220FP-5) through-hole package, the device mounts into a standard TO-220 footprint with the added benefit of a fully isolated metal tab — no insulating pad or washer is needed between the tab and the heatsink, simplifying thermal management in high-reliability builds. Power supply rejection ratio is specified at 55 dB at 120 Hz, which means the regulator attenuates 120 Hz ripple (full-wave rectified mains) by a factor of roughly 560×. For a 1 Vpp ripple on the input, less than 2 mVpp appears at the output — clean enough to feed sensitive analog stages or audio preamplifiers without additional post-filtering. On-chip protection covers over-current, over-temperature, and over-voltage — the regulator shuts down or folds back before the load or the pass element is damaged. This reduces the external component count: no need for a separate crowbar or thermal cutoff in most designs. The quiescent current is 2.5 mA typical, and the maximum supply current is 5 mA. The 2.5 mA Iq is the current the regulator draws just to stay alive — it flows to ground regardless of load, so in a battery-powered system with long idle periods, this Iq sets the floor on standby consumption. ROHM lists the part as Active with ROHS3 compliance.","metaTitle":"BA00CC0WT ROHM Semiconductor Linear Regulator, 1A, TO-220-5","metaDescription":"BA00CC0WT adjustable positive LDO, 1A output, 25V input max, 55dB PSRR, -40 to +125°C.
