TPS77401是一款具有电源正常（PG）功能的低压差线性稳压器（LDO）。该器件可提供250mA输出电流，压差仅为200mV。满载时静态电流为92μA，在禁用状态下可降至1μA。其专为宽范围输出电容的稳定性而优化，包括低ESR陶瓷电容（10μF）或小容量（1μF）钽电容。无需外接滤波电容即可实现极低噪声输出性能（55μVrms）。TPS77401针对大负载电流变化设计了快速瞬态响应，提供1.5V、1.8V、2.7V、2.8V、3.3V和5V固定电压版本及可调版本（编程范围1.5V至5.5V）。在输入电压、负载和温度变化范围内，输出电压精度为2%。该器件采用8引脚微型小外形封装（MSOP-DGK）。 由于PMOS器件表现为低阻值电阻，其压差电压极低（3.3V版本在250mA输出电流时典型值为200mV），且与输出电流成正比。此外，PMOS传输元件为电压驱动型器件，静态电流极低且与输出负载无关（0mA至250mA全范围输出电流下典型值为92μA）。这两项关键特性显著提升了电池供电系统的工作寿命。 当使能（EN）引脚接入低电平电压时器件启动。该系列LDO还具有休眠模式：向EN引脚施加TTL高电平信号可关闭稳压器，在结温25°C时静态电流降至1μA以下。TPS77401的电源正常（PG）端口为高电平有效输出，可用于实现上电复位或低电量指示。器件内部比较器通过监测稳压器输出电压来检测欠压状态：当OUT降至稳压值的82%以下时，PG进入低阻抗状态；当OUT高于稳压值的82%时，PG恢复高阻抗状态。

The TLV7081 is a single-channel, nano-power comparator that operates down to 1.7 V. The comparator is available in an ultra-small, WCSP package measuring 0.7 mm × 0.7 mm, making the TLV7081 applicable for space-critical designs like smartphones and other portable or battery-powered applications. The TLV7081 features a wide input-voltage range that is independent of supply voltage. Having an input range that is independent of supply voltage allows the TLV7081 to be directly connected to sources that are active even if the TLV7081 is not powered. The TLV7081 has an open-drain output stage that can be pulled beyond V+, making it appropriate for level translators and bipolar to single-ended converters.
