Introduction
The AP7315-26W5-7 is an advanced, low-dropout linear regulator specifically designed for applications where low quiescent current and low operating voltage are desired. It is a member of the AP7315 family and offers a low-dropout, low-power voltage regulator with a wide input voltage range and a wide output voltage range. A protection circuit can be used to protect the switching input from over-regulation, short circuit, and over-temperature conditions.Applications
The AP7315-26W5-7 has a variety of applications, such as in consumer electronics, automotive electronics, medical systems, portable computing and communications devices and other sensitive circuits that require a low-dropout, low-power voltage regulator and stable voltage.Features
The AP7315-26W5-7 features a low quiescent current, fast turn-on/off time, low input/output voltage, wide range input/output voltage, and protection circuit protection. It supports up to 50mA output current and will shut down if the input voltage falls below 8V. The device is available in various packages, including TO-263 and SOT-89.Working Principle
The AP7315-26W5-7 works by regulating voltage to a predetermined value by monitoring the input and comparing it to the set output. If a load requiring more current (or a higher voltage) is attached to the regulator, the input voltage will be drawn towards the desired output voltage, which causes the output voltage to drop and the quiescent current to increase. This is where the low-dropout feature of the regulator comes in, because it can regulate the output within a few hundred millivolts of the set voltage, even with a large input/output voltage differential.When a load is attached, the output voltage will be regulated by the regulator, while the input voltage continues to drop. Once the input voltage reaches the lower threshold voltage, the device will start to draw a quiescent current to maintain the output voltage. This quiescent current is the minimum current needed to operate the device and is thus referred to as the “leakage current” of the regulator.The AP7315-26W5-7 also features an over-voltage protection circuit which detects an excessive output voltage and shuts down the regulator to protect the connected device. The protection circuit also detects a short-circuit in the source voltage leads and shuts down the regulator to protect the connected device. In addition, the device also contains an internal over-temperature protection circuit which will shut the device down if the die temperature exceeds 130°C.Conclusion
The AP7315-26W5-7 is an advanced, low-dropout linear voltage regulator specifically designed for applications requiring a low quiescent current and low operating voltage. The device has a wide input/output voltage range and a protection circuit that can prevent over-regulation, short circuit, and over-temperature conditions. The device will shut down if the input voltage falls below 8V, but can recover once the voltage is restored. The AP7315-26W5-7 is a great solution for various applications, including consumer electronics, automotive electronics, medical systems, portable computing and communications devices and other sensitive circuits.
