TPNCP114ASN180T1G 产品概述

一、产品简介

TPNCP114ASN180T1G 是台舟电子(TECH PUBLIC)推出的一款低压差线性稳压器(LDO),具有使能控制和输出放电功能,适用于电池供电与便携式电子产品。器件在宽输入电压范围内稳定工作(1.2V 至 5.5V),以固定 1.8V 输出为目标,单通道设计并封装于经济型 SOT-23-5 封装,最大输出电流可达 300mA,兼顾低静态电流与较高负载能力。

二、主要特性

  • 正极输出(正向稳压)
  • 输入电压范围:1.2V 至 5.5V
  • 输出电压:固定 1.8V
  • 最大输出电流:300mA
  • 压差(Dropout):280mV @ 300mA
  • 静态电流(Iq):典型 25μA(工作)
  • 关断电流:约 0.5μA(使能为低电平)
  • 保护功能:限流(过流保护)、过温关断(热保护)
  • 额外功能:使能(EN)控制、输出放电(Disable 时快速放电输出)
  • 工作温度范围:-40℃ ~ +85℃(Ta)
  • 输出类型:固定输出,单通道
  • 封装:SOT-23-5

三、电气参数摘要

本器件针对低功耗与电池供电场景优化,25μA 的低静态电流有利于延长待机寿命;0.5μA 的关断电流适合长时间断电或睡眠态。280mV 的压差在满载 300mA 时仍能维持稳定输出,适合在 3.3V、5V 等主流电源旁级降压到 1.8V 的场合。

四、封装与引脚说明

  • 封装:SOT-23-5,体积小、适合空间受限设计
  • 常见引脚:VIN(输入)、VOUT(输出)、GND(地)、EN(使能)、(可带有NC或ADJ/放电控制)
  • 物理布局建议:输入/输出电容尽量靠近相应引脚布置,GND 采用单点/大面积回流以降低热阻与噪声

五、典型应用场景

  • 便携式和电池供电设备(如便携终端、手持仪表)
  • 物联网终端与传感器节点(低静态电流有利于延长待机)
  • 可穿戴设备与低功耗 MCU 电源轨(1.8V 节点)
  • 通信模块、电源管理子系统、外围模拟电路供电

六、设计注意事项

  • 电容选择:为保证稳压器稳定工作,建议在 VOUT 端使用低 ESR 的陶瓷电容(常见 1μF ~ 10μF),输入端亦需并联合适电容以抑制源阻抗。具体电容值依系统要求与器件数据手册推荐为准。
  • 热量管理:线性器件的热耗主要由 (VIN - VOUT) × IOUT 决定。高 VIN 差和大电流会产生较大功耗,SOT-23-5 自身散热有限,建议在 PCB 上增加散热铜箔并缩短引线以降低结温。
  • 使能逻辑:EN 引脚为器件上电/关断控制接口,拉高启用,拉低进入低功耗关断并触发输出放电功能(便于系统电源排序)。使能阈值及输入容限请参考器件详细规格。
  • 保护与可靠性:器件内置过流与过温保护可在异常工况下保护芯片,但不应作为长期异常工作条件下的依赖;设计时仍需避免过载与持续高温环境。

七、典型应用电路

典型应用中,VIN 通过去耦电容接入稳压器 IN 引脚,VOUT 端并联低 ESR 陶瓷电容至 GND,EN 可由 MCU 或电源管理器控制。输出放电功能可在 EN 置低时快速将输出电容放电,实现确定的电源关闭行为。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
