It has an output voltage range of 5.4V to 13.5V, and provides up to 500mA of output current.The device has an internal over temperature protection and short circuit protection, which protect the device from damage in the event of an over temperature or short circuit condition. The device also has a low quiescent current and low dropout voltage, making it an ideal choice for battery powered applications.

Working Principle

The AP1186T5-25L-U is a low dropout linear voltage regulator. The device takes input voltage and drops it to a specific level as demanded by the device’s output voltage. The linear regulator achieves this by utilizing the voltage difference between its input and output in order to control the current flow.The linear regulator is essentially a two-terminal electronic device. It consists of 3 terminals: the input voltage, the output voltage and the ground. The device is designed in such a way that it exhibits a linear relationship between its input and output voltages.The linear regulator consists of 4 components: a power switch, a voltage reference, an error amplifier and a current sink/source. The power switch is in series with the input voltage, and is responsible for controlling the current flow. The device senses the output voltage and compares it to a reference voltage.The voltage reference is used to set the desired output voltage. The error amplifier provides a difference signal between the reference voltage and the output voltage. This difference signal is then fed to the current sink/source, which then regulates the current flowing through the power switch.The power switch controls the current flow by controlling the voltage drop across it. The current is then regulated to ensure the output voltage is maintained at the desired level. As the power switch switches on and off, it changes the voltage drop across it and thus regulates the current.

Conclusion

The AP1186T5-25L-U is an excellent choice of linear voltage regulator for many applications. It is a low dropout regulator and provides a wide range of features. It has excellent line and load regulation, low noise, high efficiency, low quiescent current, low dropout voltage and an operating temperature range of -40 to +85℃. Additionally, it is RoHS compliant and UL certified. The compact size makes it ideal for portable applications where space is at a premium.
