The TCR2EE41,LM(CT delivers 73 dB of power-supply rejection at 1 kHz, meaning ripple from a switching converter upstream is attenuated by a factor of roughly 4500 before it reaches the 4.1 V output rail — a meaningful margin for analog sensor or ADC reference supplies that cannot tolerate switching noise.
Active lifecycle — no LTB pressure
This part is safe to specify into a new BOM without worrying about a forced redesign mid-production. RoHS non-compliant per the listing — verify the local regulatory exemption or plan for an exemption waiver if the end product requires RoHS conformance.
SOT-553 package — footprint for tight boards
Housed in a 5-pin SOT-553 (supplier device package ESV), the part occupies roughly 1.6 mm × 1.6 mm of board area — a fit for wearable, handheld, or multi-channel designs where every square millimeter counts.
Quiescent current and enable — always-on or gated
Typical quiescent current is 60 µA — low enough for battery-backed always-on domains, but not the ultra-low-Iq class (sub-1 µA) found in energy-harvesting parts. The Enable pin lets a GPIO or supervisor shut the regulator down when the load is idle. Over-current protection is built in — the output folds back if the load exceeds 200 mA, protecting the regulator and the downstream circuitry from a hard short.
