What this LDO brings to the board
Dropout is specified at 0.17 V maximum at the full 500 mA load. Quiescent current sits at 80 µA. The part is built for industrial temperature spans: -40°C to 125°C operating range, so it can live in outdoor telecom cabinets, engine-bay electronics, or factory-floor sensor nodes without derating concerns.
Package and mounting
Housed in a 6-lead WFDFN with exposed pad (2x2 mm body), the LTC3025IDC-1#TRPBF is a surface-mount part that needs the pad soldered to a PCB copper plane for thermal relief. 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. The Enable pin lets you gate the output for sequencing or power-save modes. Protection includes over-current, over-temperature, and short-circuit shutdown — no external clamp diode needed for the usual fault conditions.
Lifecycle and compliance
The LTC3025IDC-1#TRPBF is listed as Active in production, with ROHS3 compliance.
