Working Principle of ISL80136IBEAJZ-T7A Voltage Regulator

The ISL80136IBEAJZ-T7A is a linear voltage regulator integrated circuit (IC) that provides a low dropout (LDO) positive voltage source. It works by controlling the voltage on its output with respect to a reference voltage, while drawing a constant current from the input source. The working principle of the ISL80136IBEAJZ-T7A can be understood in three steps. First, the voltage on the input terminal is regulated to a constant voltage by the circuit’s voltage reference pin (VREF). This voltage reference could be an external source. Then, the voltage across an internal error amplifier is adjusted to provide a voltage regulation match between the output and the voltage reference. Finally, a current is pulled from the input source by the internal power transistors based on the output current level. The current drawn from the input source is regulated until the voltage across the transistors matches the VREF.

Conclusion

The ISL80136IBEAJZ-T7A Voltage Regulator is a three-terminal, low-noise, and low-voltage regulator designed for low-power, low-cost, and low-space applications. The IC offers high efficiency, low quiescent current consumption, and excellent load and line regulation. In addition, it has a wide input voltage range and features short-circuit protection. It is a great solution for applications requiring efficient low-voltage power conversion, such as those found in cell phones, tablet PCs, and embedded systems.
