Description
The LT3080 is a simple, adjustable 1.1 A linear regulator with an internal 50 µA reference that lets you set the output with a single resistor on the ISET pin. The LT3080EDD-1#TRPBF is this device in the EDD package, with Tape-and-Reel Pb-Free packaging (the “-TRPBF” suffix).
Key points
- Output is set by a single resistor from ISET to ground; easy two-part solution for adjustable supplies.
- Wide input range and high current: suitable for bench supplies and post-regulation stages.
- Includes protection features (current limit and thermal shutdown) for robust operation.
- Can be used as a traditional voltage regulator or as a simple current source in appropriate circuits.
- Requires only basic external components (primarily the resistor for Vout; output capacitor for stability).
Common uses
- Adjustable output power supplies
- Post-regulation stages in supply architectures
- Simple, programmable current sources
Packaging note
- EDD-1 indicates the specific package variant; TRPBF denotes Tape-and-Reel Pb-Free packaging. For exact pinout and capacitor requirements, consult the LT3080 datasheet and the packaging document for LT3080EDD-1#TRPBF.
