概述

Description

LT3021ES8-1.2#PBF is a fixed-output low-dropout regulator (LDO) from Linear Technology (now Analog Devices). It delivers a precise 1.2 V rail in an 8‑pin ES8 Pb‑free package. Key points:
- Fixed 1.2 V output with enable/shutdown control
- Low dropout and low quiescent current
- Good line and load regulation
- Protection: current limit and thermal shutdown
- Requires an appropriate output capacitor for stability (per datasheet)
How to use (high level):
- Connect Vin to a supply above 1.2 V
- Connect Vout to the 1.2 V rail, with the recommended output capacitor
- Bring EN high to enable (or per variant’s behavior)
Typical applications:
- 1.2 V core rails for microprocessors, memories, ASICs, or other digital circuitry
- Battery-powered or compact systems needing a stable 1.2 V rail
Note: For exact electrical specs, pinout, capacitor values, and stability requirements, refer to the LT3021 datasheet and the product page for LT3021ES8-1.2#PBF.

Features

Here are the typical features of the LT3021ES8-1.2#PBF (1.2V fixed-output LDO in an 8‑pin Pb‑free package):
- Fixed 1.2V output LDO in 8-pin ES8 package (Pb-free)
- Ultra-low quiescent current (battery-powered designs)
- Low dropout voltage suitable for low-V input supplies
- Good line and load regulation with low output noise
- Enable/shutdown control to turn the regulator off
- Overcurrent protection and thermal shutdown
- Fast transient response
- Suitable for portable/compact electronics
Note: For exact electrical specs (input range, current capability, dropout, accuracy, PSRR, etc.), please refer to the official datasheet.

Package

8-pin MSOP (Plastic Small Outline Package), Pb-free (PBF).

Pinout

- Pin count: 8 pins (ES8 package)
- Function: Fixed-output LDO regulator (1.2 V). Pins include VIN (input), VOUT (1.2 V output), EN (enable/shutdown), GND (ground); remaining pins are No Connect (NC) for this fixed-output version.

Manufacturer

Analog Devices, Inc. (formerly Linear Technology). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.

Application

LT3021ES8-1.2#PBF is a fixed 1.2V LDO regulator (MSOP-8). Typical applications include:
- Portable/battery-powered electronics needing a 1.2V rail
- Core-voltage supply for microprocessors, FPGAs, DSPs
- Noise-sensitive analog front-ends and ADC/DAC reference rails
- Post-regulation for SoCs/microcontrollers and other PMIC rails
(Stable 1.2V rail with low dropout and good PSRR for small, power-efficient systems.)
