66 dB PSRR at 100 Hz — cleaning the ripple from a rectified rail
The MAX15006AATT+ is a 3.3 V fixed-output linear regulator from Analog Devices, rated for 50 mA continuous output. Its 66 dB PSRR at 100 Hz means it attenuates the 100/120 Hz ripple from a full-wave rectified AC supply by a factor of 2000 — a sensor bias rail or CAN transceiver supply fed from a 24 V industrial bus sees clean DC without a post-filter. Input range goes up to 40 V, so it sits comfortably on a 24 V industrial rail or a 12 V automotive bus without needing a pre-regulator. The 1 V dropout at 50 mA means the input must stay above 4.3 V to hold regulation — fine for any rail that doesn't dip below 4.5 V during cranking or brownout.
17 µA quiescent, 150 µA max supply — always-on current budget
Quiescent current is 17 µA typical, and the total supply current tops out at 150 µA even at full load. For an always-on microcontroller or transceiver that spends most of its time in sleep, the regulator's own draw is negligible — it won't drain a coin cell or backup supercap overnight. The -40°C to 125°C operating range covers automotive under-hood and industrial enclosure ambient. The exposed pad on the 6-TDFN (3x3 mm) package must be soldered to a copper land on the PCB — without that thermal path, the junction temperature rises above the 125°C limit at full load in a 85°C ambient.
Active production — no obsolescence risk for new designs
ROHS3 compliant — no exemptions for lead or other restricted substances. The part passes the current RoHS directive without a waiver, so it ships into EU, UK, and other regulated markets without compliance paperwork.
