DESCRIPTION
The LM2930 3-terminal positive regulator features an ability to source 150 mA of output current with an input-output differential of 0.6V or less. Efficient use of low input voltages obtained, for example, from an automotive battery during cold crank conditions, allows 5V circuitry to be properly powered with supply voltages as low as 5.6V. Familiar regulator features are also provided.
Designed originally for automotive applications, the LM2930 and all regulated circuitry are protected from reverse battery installations or 2 battery jumps. During line transients, such as a load dump (40V) when the input voltage to the regulator can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both internal circuits and the load. The LM2930 cannot be harmed by temporary mirror- image insertion.
Fixed outputs of 5V and 8V are available in the plastic TO-220 and SFM power packages.

描述
LM2930 3端子正電壓穩壓器具備 150 mA 的輸出電流能力，且輸入與輸出電壓差低於 0.6V。此設計可有效利用低壓輸入，例如汽車電池在冷車啟動時的低電壓情況，使 5V 電路在供應電壓低至 5.6V 時仍能正常運作。此外，該穩壓器還提供標準保護功能，包括反接電池保護、40V 負載突降保護、短路保護與熱過載保護。
LM2930 最初為汽車應用設計，可保護穩壓電路免受反接電池或雙電池衝擊的影響。在電壓瞬變（如 40V 負載突降）期間，當輸入電壓短暫超過最大額定工作電壓時，穩壓器會自動關閉，以保護內部電路與負載。LM2930 亦可防止錯誤極性插入導致的損壞。
