LP3986TL-2518/NOPB TI LDO Voltage Regulator | 8-DSBGA (1.56x1.56) | Dual Output, 250mA, Low Noise

Product Overview

The LP3986TL-2518/NOPB is a high-performance, dual-output low-dropout (LDO) voltage regulator from Texas Instruments. It provides two independent regulated outputs: 2.5V and 1.8V, each capable of delivering up to 250mA of load current. Housed in a compact 8-DSBGA (1.56x1.56mm) package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP3986 features a low dropout voltage of typically 120mV at full load, enabling efficient operation even with small input-to-output voltage differentials. Its low quiescent current (30µA typical per channel) makes it suitable for battery-powered devices. The device also includes enable pins for each output, allowing independent power management.

產品概述

LP3986TL-2518/NOPB 是德州儀器（TI）推出的一款高性能雙輸出低壓差線性穩壓器（LDO）。它提供兩個獨立的穩壓輸出：2.5V 和 1.8V，每個輸出可提供高達 250mA 的負載電流。器件採用緊湊的 8-DSBGA（1.56x1.56mm）封裝，非常適合需要低噪聲和高電源抑制比（PSRR）的空間受限應用。LP3986 在滿載時典型壓差僅為 120mV，即使在輸入輸出電壓差較小的情況下也能高效工作。其低靜態電流（每通道典型值 30µA）使其適用於電池供電設備。器件還包含每個輸出的使能引腳，支持獨立的電源管理。
