50 mA fixed 5V LDO with a tight dropout — what that means on the rail
Its maximum dropout voltage of 0.17V at the full 50 mA load means you can hold the 5V rail with an input as low as 5.17V — useful when the pre-regulator bus is marginal or you're running from a battery near its end-of-discharge voltage. Control features include an error flag and a shutdown pin, and protection covers overcurrent and overtemperature events.
SOT-23-6 — small footprint, reworkable
The part comes in a 6-lead SOT-23 package (SOT-23-6). That's a small, low-profile surface-mount package that reflows cleanly with standard profiles and is hand-reworkable with hot air if you're careful — the leads are on the sides, not under the body, so you can see the joints and touch them up. Pin 1 orientation is marked by a dot or notch on the package body.
The anyCAP® series is stable with any output capacitor type — ceramic, tantalum, or electrolytic — which simplifies the BOM and avoids the ESR windowing that older LDOs require.
