L7812C 的典型應用通過降壓電阻降低功耗

使用 STMicroelectronics 的 L7812C 的參考設計

設計簡介

L7812C 的典型應用通過降壓電阻器降低功耗。 L78 系列三端正穩壓器有 TO-220、TO-220FP、D2PAK 和 DPAK 封裝以及多種固定輸出電壓，使其可用于廣泛的應用。這些調節器可以提供本地卡上調節，消除與單點調節相關的分配問題。每種類型都嵌入了內部電流限制、熱關斷和安全區域保護，使其基本上堅不可摧。如果提供足夠的散熱，它們可以提供超過 1A 的輸出電流

說明

Typical Application for L7812C Reducing power dissipation with dropping resistor. The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D2PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds internal current limiting, thermal shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current
