Active production — BOM-fit note
The MCP1725-3002E/MC: It is ROHS3 compliant, meeting current environmental requirements for European and global markets.
Key parametrics for the supply rail
This LDO delivers a fixed 3V output at up to 500mA — sized for powering 3V logic, sensor rails, or MCU analog supplies where a clean, regulated voltage is needed. Quiescent current is 220 µA typical — low enough for battery-powered applications that spend most of their time in active mode, though not optimized for deep sleep where sub-µA Iq parts would be preferred.
PSRR and noise rejection
Power supply rejection ratio is 60 dB at 100 Hz — this attenuates 100 Hz ripple from a mains-derived rectifier by a factor of 1000, making the part suitable for audio or measurement circuits sensitive to line-frequency hum.
Thermal and protection envelope
On-chip protection includes over-temperature shutdown, short-circuit current limiting, and under-voltage lockout (UVLO) — the regulator survives output shorts and input brownout conditions without external clamp diodes.
Control features include an enable pin for power sequencing and a power-good output for reset or supply-rail monitoring — both are available on the 8-pin DFN footprint.
