BL9161G-33BADRN 产品概述
一、产品简介
BL9161G-33BADRN 是贝岭（BELLING）推出的一款固定输出线性稳压器（LDO），输出电压为 3.3V，最大输出电流可达 300mA。器件采用紧凑的 DFN-4L (1×1 mm) 封装，适合空间受限的便携与消费类电子设计，内建过流保护与热关断功能，可靠性高。
二、主要电气性能
- 输出类型：固定（3.3V）
- 最大输出电流：300mA
- 最大工作电压（输入）：6V；最低输入电压建议 ≥ VOUT + 压差（≈3.6V）
- 压差（Dropout）：300mV @ 300mA
- 静态电流（Iq）：200µA
- 噪声：180µVrms
- 电源纹波抑制比（PSRR）：55dB @ 10kHz
- 保护特性：过流保护、热关断
- 工作温度范围：-40℃ ~ +85℃（Ta）
- 输出极性：正极，单通道输出
三、封装与引脚说明
器件封装为 DFN-4L (1×1 mm)，四引脚小型化设计，封装底部设有散热焊盘。常见应用中引脚包括 VIN、VOUT、GND 与控制/检测引脚（具体引脚定义与引脚排列请以官方数据手册为准）。
四、热设计与 PCB 布局建议
线性稳压器的功耗与输入输出压差和负载电流直接相关：Pd = (Vin − Vout) × Iout。举例在 Vin=6V、Iout=300mA 时，Pd≈0.81W，需注意热管理。建议：
- 将输入电压控制在尽量接近 3.3V 的范围以降低功耗。
- 在 PCB 下方或周围配置足够铜箔与散热焊盘，并使用导热过孔连接多层铜层以扩散热量。
- 输入侧加 0.1µF 陶瓷旁路电容，输出侧使用 1µF~10µF X5R/X7R 陶瓷电容（具体容量与 ESR 要求请参阅数据手册以保证稳定性）。
五、典型应用场景
适合为 3.3V 供电的微控制器、传感器、射频前端与低功耗便携设备供电；由于低压差与较低静态电流，也适用于电池供电场合，但在高电压差或大电流输出情况下需评估散热。
六、选型与使用注意事项
- 如需在高 Vin 与高 Iout 条件下长期工作，必须进行热仿真和实测温升评估。
- 输出与输入电容的类型与容量对稳定性和瞬态响应影响显著，请遵循厂商推荐的外部元件配置。
- 对于更严格的噪声或更高 PSRR 要求，可结合输入滤波或后级滤波方案优化。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
