Description
LT3070MPUFD is an adjustable, high‑performance linear regulator in Linear Technology’s LT3070 family. It uses an external resistor network to set Vout and provides robust protection including current limit/short‑circuit protection and thermal shutdown. The MPUFD suffix identifies a Pb‑free, RoHS‑compliant package variant with a particular pinout (check the datasheet for the exact package type and pad layout). For precise operation and electrical specs, consult the LT3070 datasheet and product page.
Pinout
- Pin count: 8 pins (MSOP-8/8-lead package – MPUFD suffix).
- Function: Adjustable high-current positive linear regulator (voltage regulator with feedback, current limit/overload protection).
- Function: Adjustable high-current positive linear regulator (voltage regulator with feedback, current limit/overload protection).
Manufacturer
Manufacturer: Analog Devices, Inc. (the LT prefix comes from Linear Technology, which AD acquired in 2017).
What kind of company: a multinational American semiconductor company that designs and manufactures analog, mixed‑signal, and power-management integrated circuits.

Application
LT3070MPUFD is a precision, adjustable current source/sink. Typical application areas:
- Constant-current LED drivers and backlighting
- Programmable current source/sink for power management and load regulation
- Current-limited driver for DC-DC converters and protection schemes
- Test, measurement, and instrumentation equipment requiring stable, adjustable current
- Automotive/industrial lighting and displays with robust current regulation
- Laboratory bench current source for experiments and development
(Uses: high-accuracy, low-drift current regulation in compact packaging.)
