The LP2986 is a 200-mA high-precision LDO regulator with a wide input voltage supply. The device has two output voltage modes: a fixed-precision output mode and an adjustable output voltage via an external resistive divider.

Using an optimized Vertically Integrated PNP (VIP) process, the LP2986 delivers superior performance:

Dropout Voltage: Typically 180 mV at 200-mA load, and 1 mV at 1-mA load.
GROUND Pin Current: Typically 1 mA at 200-mA load, and 200 μA at 10-mA load.
Sleep Mode: The LP2986 draws less than 1 μA quiescent current when SHUTDOWN pin is pulled low.
ERROR Flag: The built-in ERROR flag goes low when the output drops approximately 5% below nominal.
Precision Output: The standard product versions available can be pin-strapped (using the internal resistive divider) to provide output voltages of 5 V, 3.3 V, or 3 V with ensured accuracy of 0.5% (A grade) and 1% (standard grade) at room temperature.

For all available packages, see the orderable addendum at the end of the data sheet.

PMP20873 — 效率高達 99% 且基於 GaN 的 1kW CCM 圖騰柱功率因數校正 (PFC) 轉換器參考設計

連續導通模式 (CCM) 圖騰柱功率因數校正 (PFC) 是一款簡單但有效率的電源轉換器。若要達到 99% 效率，必須考量許多設計細節。 PMP20873 參考設計採用 TI 的 600VGaN 功率級 LMG3410，以及 TI 的 UCD3138 數位控制器。設計概覽提供關於 CCM 圖騰柱拓撲結構運作的更多細節，說明電路的詳細設計考量，以及磁性元件與韌體控制的設計考量。此轉換器設計的運作頻率為 100KHz。在 AC 線路交越時採用緩啟動可將電流突波最小化，並降低 THD。 PFC 韌體會即時量測 AC 電流與 PFC (...)
