具有反饋關(guān)斷功能的 LT1120IN8 5V
穩(wěn)壓器的典型應(yīng)用電路。 LT1120 是一款集成在單個(gè)單片芯片上的微功耗正穩(wěn)壓器和自由集電極
比較器。 LT1120 僅需 40 uA
電源電流即可提供超過(guò) 125mA 的輸出電流。輸入電壓范圍為 4.5V 至 36V,125mA 時(shí)壓差電壓為 0.6V。壓差隨著
負(fù)載電流的降低而降低。該芯片還包括一個(gè) B 類(lèi)輸出 2.5V 基準(zhǔn),可以提供或吸收電流。關(guān)斷引腳允許輸出邏輯關(guān)斷

Typical Application Circuit for LT1120IN8 5V Regulator with Feedback Shutdown. The LT1120 is a combination micropower positive regulator and free collector comparator on a single monolithic chip. With only 40 uA supply current, the LT1120 can supply over 125mA of output current. Input voltage range is from 4.5V to 36V and dropout voltage is 0.6V at 125mA. Dropout voltage decreases with lower load currents. Also included on the chip is a class B output 2.5V reference that can either source or sink current. A shutdown pin allows logic shutdown of the output
