LP3988IMF-3.0/NOPB TI LDO Regulator | SOT-23-5 | 3.0V Output, 150mA

Product Overview

The LP3988IMF-3.0/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.0V output with a maximum current of 150mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained and power-sensitive applications. With a low dropout voltage of typically 120mV at 150mA load, it ensures efficient operation even when the input voltage is close to the output. The LP3988 features a low quiescent current of 30µA (typical) and a shutdown mode that reduces current to less than 1µA, extending battery life in portable devices. Its stability with ceramic output capacitors (1µF or larger) simplifies design and reduces external component count.

產品概述

LP3988IMF-3.0/NOPB 是德州儀器（TI）推出的一款高性能低壓差線性穩壓器（LDO），可提供固定的 3.0V 輸出電壓和最高 150mA 的輸出電流。該器件採用緊湊的 SOT-23-5 封裝，具有優異的線性調整率和負載調整率，非常適合空間受限且對功耗敏感的應用。在 150mA 負載下，典型壓差僅為 120mV，確保在輸入電壓接近輸出電壓時仍能高效工作。LP3988 的典型靜態電流為 30µA，關斷模式下電流低於 1µA，有助於延長便攜設備的電池壽命。其對陶瓷輸出電容器（1µF 或更大）的穩定性簡化了設計並減少了外部元件數量。
