H7236-1 产品概述
一、产品简介
H7236-1 是上海矽朋（Siproin）推出的一款固定输出型低压差线性稳压器（LDO），输入电源可达 15V，固定输出 3.6V，最大输出电流 400mA。封装为紧凑的 SOT-23-3，适合对尺寸和静态功耗要求较高的便携与嵌入式应用。器件内置过流保护，工作温度范围为 -40℃ 至 +85℃。
二、主要性能要点
- 输出电压：3.6V（固定）
- 最大输出电流：400mA（峰值）
- 输入电压上限：15V
- 压差（Dropout）：170mV @ 100mA（随电流增大而上升）
- 静态电流（Iq）：典型 1μA，极适合低功耗/待机场景
- 电源纹波抑制比（PSRR）：40dB @ 1kHz，具备良好纹波抑制能力
- 保护功能：过流保护（OCP）
- 输出极性：正极，单路输出
- 封装：SOT-23-3，适合小尺寸 PCB 布局
三、典型应用场景
- 低功耗传感器节点、IoT 终端与便携设备的局部供电
- 电池供电系统的稳压输出（睡眠态能耗敏感）
- 单片机、模拟前端及外设的 3.6V 供电（注意热耗限制）
- 工业与消费类电子的辅助电源（需评估功耗与散热）
四、热管理与使用注意事项
在 SOT-23-3 小封装上，热阻限制了器件在高压差和大电流下的持续输出能力。以 VIN=15V、VOUT=3.6V、IO=400mA 为例，功耗约 4.56W，单片封装无法自然散热至安全温度。建议：
- 避免在高 VIN–VOUT 差值下长期满载工作；若需长期大电流输出，应采用降压预稳或开关转换器作为前级。
- 通过大面积铜箔和多层 PCB 热过孔改善散热，必要时考虑金属散热片或外部散热方案。
- 参考器件数据手册中的最大功耗与热阻参数，计算实际允许的连续电流。
五、外围电容与 PCB 布局建议
- 在输入端和输出端分别放置贴近引脚的去耦电容，典型建议：输入 1μF10μF，输出 1μF10μF（陶瓷）；具体稳定性依赖于电容 ESR，建议按厂商资料选择并验证电路稳定性。
- 输出电容靠近 LDO 输出脚放置，地线采用短而粗的回流路径；GND 引脚应与 PCB 地平面良好连接以利散热与抑制噪声。
六、选型建议
H7236-1 以超低静态电流和良好 PSRR 为亮点，适合电池供电、待机时间要求长且负载电流中低的场合。若系统需要在高输入电压差下持续大电流输出，需评估热管理能力或优先考虑前级降压转换器配合本 LDO 实现更高效率与可靠性。

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.
