芝电子元件及存储装置株式会社(“东芝”)开发了74种类型,最大输出电流为300mA的SMV小型贴片式封装LDO稳压器“TCR3UF系列”,该系列产品极大地扩展了东芝原有的产品阵容。

全新的“TCR3UF系列”可用于物联网设备、可穿戴设备、移动设备等的电源管理。它具有消耗电流低的特性,实现了业内领先的高纹波抑制比与高速负载瞬态响应的平衡[1]。它们还内置有过热保护、过流保护、浪涌电流限制等各种保护功能。
除了早前发布的紧凑型和薄型WCSP4F封装“TCR3UG系列”和小型通用DFN4封装“TCR3UM系列”产品以外,此次还发布了全新的引脚型和通用型SMV封装“TCR3UF系列”。
TCR3UF系列适用于长时间工作的电池供电设备和易受噪声等电压波动影响的传感器电源。该系列产品按0.8V至5.0V的电压输出范围,产品类型多达37种,同时如按具不具有自动放电功能来划分,产品总类型共达74种。可满足客户根据预期应用进行产品选择。

注:
[1] 基于输出电流为300mA的LDO稳压器,截止于2020年1月的东芝调查。
