Dropout is specified at 0.17 V maximum at the full 500 mA load. Quiescent current sits at 80 µA.
The small footprint suits dense layouts, but the thermal path is through the pad — a via array under the part is standard practice for keeping junction temperature in check at 500 mA. Protection includes over-current, over-temperature, and short-circuit shutdown — no external clamp diode needed for the usual fault conditions.
The part comes in a 6-lead WFDFN with exposed pad, supplier package designation 6-DFN (2x2 mm). It is supplied in Tape & Reel (TR) or Cut Tape (CT) options.
A close functional peer is the LT3063HMS8E#TRPBF, also a positive adjustable LDO from Analog Devices, but it offers higher PSRR (85 dB at 120 Hz) and a wider input range (up to 45 V) at a lower 200 mA output. The LTC3025IDC-1#TRPBF is the right pick when you need 500 mA in a smaller 2x2 mm package.
