The TLV755P is an ultra-small, low quiescent current, low-dropout regulator (LDO) that sources 500mA with good line and load transient performance. The TLV755P is optimized for a wide variety of applications by supporting an input voltage range from 1.45V to 5.5V. To minimize cost and solution size, the device is offered in fixed output voltages ranging from 0.6V to 5V to support the lower core voltages of modern microcontrollers (MCUs). Additionally, the TLV755P has a low IQ with enable functionality to minimize standby power. This device features an internal soft-start to lower inrush current, thus providing a controlled voltage to the load and minimizing the input voltage drop during start up. When shutdown, the device actively pulls down the output to quickly discharge the outputs and provide a known start-up state.

The TLV755P is stable with small ceramic output capacitors allowing for a small overall solution size. A precision band-gap and error amplifier provides a typical accuracy of 1%. All device versions have integrated thermal shutdown, current limit, and undervoltage lockout (UVLO). The TLV755P has an internal foldback current limit that helps reduce the thermal dissipation during short-circuit events.

The TLV755 is available in the popular WSON, X2SON, and SOT23-5 (DRV, DQN, and DBV) packages. This device is also available in a thermally enhanced SOT23-5 (DYD) package with a thermal pad that provides significantly reduced thermal resistance compared to a standard SOT23-5 package.

TIDA-060039 — 電感式觸控及磁性轉盤非接觸式使用者介面參考設計

此參考設計採用電感及霍爾效應感測技術以提供人機介面。電感式感測裝置可在無縫表面建立八個不同的觸控按鈕，而霍爾效應感測器則可用於建立磁性轉盤，其可轉動並用作額外按鈕。

使用感應式感測觸控按鈕提供完整的解決方案，該解決方案使用按壓之力來決定按鈕的按壓動作。這使觸控按鈕可以與手套一起使用，同時忽略環境因素，如按鈕表面髒污或損壞。霍爾效應感測器轉盤可產生非接觸式旋轉，與電位計或旋轉編碼器等傳統接觸式實作方式相比，其磨損與撕裂程度有所改善。
