Overview

Description

LT3021EDH#PBF is Linear Technology’s Pb-Free, EDH‑package version of the LT3021 low‑dropout regulator (LDO). It’s designed to generate a stable, low-voltage rail from a higher input with simple external resistors.
Key points
- LDO regulator: adjustable output (via resistor divider) with a fixed Vref, plus an optional bypass for noise reduction.
- Output current: capable of delivering tens to hundreds of milliamps (typical for small-scale analog/microcontroller supplies).
- Protections: includes enable/shutdown, current limit, and thermal/overload protection.
- Package: EDH is the small 3x3 mm 8‑pin Pb‑free package; PBF denotes Pb‑free compliance.
- Typical use: low-noise, compact power for microcontrollers, sensors, and analog front-ends in battery-powered or space-constrained apps.
What to do next
- Check the datasheet for exact electrical specs (VIN range, Vout calculation, quiescent current) and the recommended input/output capacitors.
- Use the EN pin to disable the regulator when power saving is needed.
- Refer to application notes for layout and bypass recommendations.

Package

8-pin TSSOP package (Pb‑free, RoHS).

Pinout

8 pins. It’s an 8‑pin low‑dropout regulator (LDO) with adjustable output and an enable input (plus protection features such as current limit/thermal shutdown).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management ICs (including LDOs). It acquired Linear Technology in 2017, which originally developed the LT series.

Application

LT3021EDH#PBF is a low-noise, low-dropout linear regulator. Suitable applications include:
- Battery-powered portable devices and wearables
- Precision analog rails for ADCs, DACs, op-amps, and instrumentation
- Microcontroller and digital peripheral supplies
- RF/telecom front-ends and other noise-sensitive circuits
- Medical instrumentation and test/measurement equipment
- Automotive and industrial sensors and control systems
Use when a clean, stable supply is needed with good line/load regulation and fast transient response.
