Présentation
Description
LT3097ADJC#PBF is the adjustable version of Linear Technology’s LT3097, a precision current regulator IC. It is designed to implement a programmable constant-current source (or sink) using an external resistor to set the output current. Because the current can be set externally, it’s well suited for LED driving, battery charging currents, or as a stable, low-noise current reference in power-management circuits. The ADJ in the part name indicates the output current is user-settable rather than fixed. The #PBF suffix denotes Pb-Free packaging, with ADJC indicating a specific package/variant.
Key points:
- Output current is programmable via an external resistor.
- Typical uses: LED drivers, programmable current sources, precision current references.
- Pb-Free (PBF) package; refer to the datasheet for exact package types and pinout.
- For precise electrical specs (range, accuracy, protections), consult the LT3097 datasheet or product page.
If you want, I can pull and summarize the datasheet’s main figures.
