TLV71125125DSET TI LDO Regulator | 6-WSON (1.5x1.5) | Dual Output 2.5V/1.25V, 200mA

Product Overview

The TLV71125125DSET from Texas Instruments is a dual-output, low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact 6-pin WSON package (1.5mm x 1.5mm), it provides two independent regulated outputs: 2.5V and 1.25V, each capable of delivering up to 200mA of load current. With a low dropout voltage of typically 200mV at full load, this device ensures efficient power conversion even when the input voltage is close to the output. The TLV71125125DSET features high PSRR (70dB at 1kHz) and low output noise (30µVrms), making it ideal for noise-sensitive analog and RF circuits. It also includes enable pins for each output, allowing independent power sequencing and shutdown to reduce quiescent current to less than 1µA.

產品概述

TLV71125125DSET 是德州儀器（TI）推出的雙輸出低壓差線性穩壓器（LDO），專為空間受限的應用設計。它採用緊湊的 6 引腳 WSON 封裝（1.5mm x 1.5mm），提供兩個獨立的穩壓輸出：2.5V 和 1.25V，每個輸出可提供高達 200mA 的負載電流。在滿載條件下，典型壓差僅為 200mV，確保即使在輸入電壓接近輸出時也能高效轉換。該器件具有高 PSRR（1kHz 時 70dB）和低輸出噪聲（30µVrms），非常適合噪聲敏感的模擬和射頻電路。它還包含每個輸出的使能引腳，允許獨立的電源排序和關斷，將靜態電流降至 1µA 以下。
