概要

Description

LT3021EDH#TRPBF is Linear/Analog Devices’ LT3021 low‑dropout regulator in a Pb‑free EDH package, delivered on Tape & Reel. The #TRPBF suffix only denotes tape & reel Pb‑free packaging.
What it is:
- An adjustable-output LDO with an enable/shutdown input.
- Features typical protection: current limit and thermal shutdown.
- Used to generate precise, low-noise supply rails for microcontrollers, sensors, and analog circuits.
What to expect:
- Output voltage set by an external resistor divider.
- EN (enable) to turn the regulator on/off.
- Stable operation with appropriate input/output capacitors as recommended in the datasheet.
How to use (high level):
- Connect Vin to your source with a suitable input capacitor close to the device.
- Place the recommended output capacitor on Vout.
- Set Vout with external resistors (feedback network) per the datasheet.
- Drive EN high to enable.
For exact electrical specs, pinout, and recommended circuits for the EDH/TRPBF variant, refer to the LT3021 datasheet.

Features

Here are the typical features of the LT3021EDH#TRPBF (LT3021 family) LDO in EDH package:
- Low-dropout regulator with enable/shutdown control
- Adjustable output via resistor divider (also available in fixed-output variants)
- Very low quiescent current (ideal for battery/power‑sensitive apps)
- Wide input voltage range with good line and load regulation
- Fast transient response to load changes
- Output current protection via current limit
- Thermal/shutdown protection for robust operation
- Reverse-current/short‑circuit protection (protective features)
- Small 8-pin EDH package; RoHS-compliant; Tape & Reel (TRPBF) packaging
Note: exact output voltage options and absolute ratings vary by variant; consult the LT3021 datasheet for precise specs and pinout.

Package

8-pin DFN (plastic, with exposed pad) package. Suffix TRPBF means Tape & Reel, Pb-Free.

Pinout

8 pins. It is a micropower low-dropout (LDO) regulator with an enable input (adjustable output via feedback network).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). ADI is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits. It acquired Linear Technology (the original maker of LT parts) in 2017, and LT parts are now marketed under the Analog Devices umbrella.

Application

LT3021EDH#TRPBF is a low-noise, low-quiescent LDO suitable for portable and precision analog rails. Typical applications: battery-powered devices and wearables; post-regulation supplies for microcontrollers, DSPs, and FPGAs; bias and reference rails for precision ADC/DAC front-ends; sensor interfaces and instrumentation amplifiers; RF/communication circuits requiring clean Vcc; and general analog rails in medical and industrial instrumentation.

Equivalent

Direct equivalents aren’t published here. For exact substitutes, use LT’s Cross-Reference tool or DigiKey/Mouser cross-reference by LT3021EDH#TRPBF. In practice, look for other 150 mA LDOs in an 8-pin Pb-free package with a similar pinout (MSOP/TSSOP), from TI (TLV/LMx), Onsemi (NCP/NCV), Analog Devices (ADP), Microchip (MCP1700/1710). Always verify output voltage, dropout, quiescent current, and pinout.
