产品详情

Low Noise ±12V Power Supply from a Single-Ended 15V Input Supply

LTC3260 是一款低噪声、双极性输出电源,包括一个兼具正和负 LDO 稳压器的负输出充电泵。充电泵在一个 4.5V 至 32V 的宽输入范围内运作,并能够输送高达 100mA 的输出电流。每个 LDO 稳压器可提供高达 50mA 的输出电流。负 LDO 后置稳压器采用充电泵输出来供电。LDO 输出电压可使用外部电阻分压器进行调节。

工具及仿真模型

LTspice

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

To launch ready-to-run LTspice demonstration circuits for this part:

Step 1: Download and install LTspice on your computer.

Step 2: Click on the link in the section below to download a demonstration circuit.

Step 3: If LTspice does not automatically open after clicking the link below, you can instead run the simulation by right clicking on the link and selecting “Save Target As.” After saving the file to your computer, start LTspice and open the demonstration circuit by selecting ‘Open’ from the ‘File’ menu.
