Application Fields
ADP1761ACPZ-1.2-R7 Voltage Regulator is very suitable for personal digital assistant (PDA), live data communication, and mobile office applications. It can also be used in multi-function printers, large scale servers, health monitoring, instrumentation, and scientific labs. The low IQ and high efficiency of the regulator makes it ideal for battery-powered hand-held or portable electronic systems due to its ability to reduce the overall power consumption.
Working Principle
The linear voltage regulator works by taking the input voltage and then reducing it to whatever voltage value or range of values that is required for the specific application. It does this by using a series of transistors, capacitors, and resistors. The input signal is fed into a switching device that controls how much power is being fed into a voltage regulating device. This voltage regulating device then produces the output signal, which is fed back into the switching device, which can then adjust the amount of current it allows to flow through the voltage regulating device.
The output voltage of the linear voltage regulator is therefore determined by the feedback signal. When the output voltage needs to be increased, the feedback signal is used to increase the current flow in the voltage regulating device, and this in turn increases the output voltage. Similarly, when the output voltage needs to be decreased, the feedback signal is used to reduce the current flowing in the voltage regulating device, and this in turn reduces the output voltage.
ADP1761ACPZ-1.2-R7 offers a number of features that make it ideal for low quiescent current applications. These include a wide input voltage range, fast transient response, and a low output noise. Additionally, the device is designed with current limiting and thermal shutdown protection.
