LT1120ACN8
穩壓器的典型應用電路，用于將
比較器用作
運算放大器進行補償。 LT1120A 是一款集成在單個單片芯片上的微功耗正穩壓器和自由集電極比較器。只需 20 uA 的
電源電流，LT1120A 就能提供超過 125mA 的輸出電流。輸入電壓范圍為 4.5V 至 36V，125mA 時壓差電壓為 0.6V。壓差隨著
負載電流的降低而降低。該芯片還包括一個 B 類輸出 2.5V 基準，可以提供或吸收電流。這使得它可以用作電源分配器或輔助輸出。關斷引腳允許輸出邏輯關斷

Typical Application Circuit for LT1120ACN8 Regulator for Compensating the Comparator as an Op Amp. The LT1120A is a combination micropower positive regulator and free collector comparator on a single monolithic chip. With only 20 uA supply current, the LT1120A 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. This allows it to be used as a supply splitter or auxiliary output. A shutdown pin allows logic shutdown of the output
