LT3021EDH#TRPBF

The LT3021 is a low-noise, precision low-dropout (LDO) regulator from Linear Technology. LT3021EDH#TRPBF is that device in the EDH package, delivered in Tape-and-Reel Pb-Free packaging. It can be configured for fixed or adjustable output using external resistors, and includes an enable/shutdown input. The part is designed for low quiescent current, good line/load regulation, and stable operation in space-constrained, portable analog supplies. Typical uses include providing clean Vout rails for microcontrollers, sensors, and analog circuits in battery-powered devices. Pinout and exact electrical specs (output voltage options, dropout, PSRR, quiescent current) vary by variant; the EDH suffix only denotes the packaging. For precise details, consult the LT3021 datasheet and the product page. If you share your target output voltage, I can point to the exact variant and a basic application sketch.

Key features of LT3021EDH#TRPBF (8-pin EDH, Tape & Reel):
- Adjustable low-dropout regulator in 8-lead EDH package.
- Adjustable output via external divider with a 1.22V reference.
- Low quiescent current and suitable for battery-powered apps; low dropout for efficiency.
- Fast line/load transient response; good PSRR and stability with ceramic capacitors.
- Enable/Shutdown control to turn regulator on/off.
- Protection features: current limit, thermal shutdown, and reverse-current protection.
- Stable with common ceramic output capacitors.
- TRPBF packaging (RoHS Pb-free), suitable for automatic assembly.

- Pin count: 8 pins (MSOP-8 package, EDH).
- Function: Low-dropout adjustable linear regulator (LDO) with an enable pin; output voltage set by an external resistor network.

- Manufacturer: Analog Devices, Inc. (ADI). The LT3021 was originally from Linear Technology; after Linear Technology’s acquisition in 2017, the product is now under Analog Devices.
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs (including power management, data converters, amplifiers, sensors, etc.).

LT3021EDH#TRPBF is a high-precision, low-noise voltage reference suitable for precision analog systems. Typical applications include:
- Precision ADC/DAC reference rails and calibration
- Sensor front-ends and instrumentation amplifiers
- Portable, battery-powered equipment needing a stable reference
- Medical, automotive, and industrial instrumentation requiring low drift and good line/load regulation
- Calibration and test equipment as a reference source
- Microcontroller/analog-supply rails where a clean reference improves accuracy

EDH is the 8‑pin EDH package code. TRPBF indicates Tape‑and‑Reel, Pb‑Free.
