Linear Voltage Regulators (LVRs) are electrical components that provide a stable output voltage, they are also known as linear regulators. The NCP720BMT135TBG is a linear voltage regulator that features voltage monitoring. This voltage regulator, manufactured by ON Semiconductor, is capable of providing an output current of up to 1A.

The NCP720BMT135TBG consists of a voltage reference and error amplifier, a series low-dropout (LDO) regulator, a self-biasing control logic, a power transistor and its associated control circuitry, and also a voltage monitoring circuit. All components are housed in a small 8 pin SSOP (shrink small-outline-package) package. The maximum junction temperature of this device is set at 125°C.

The NCP720BMT135TBG has an input voltage range of 2.7V to 6.5V and its maximum output voltage is 5.5V. This allows it to be used in a wide variety of applications, including microprocessors, digital signal processors, and other consumer electronics that require high precision output voltage regulation.

The primary benefit of the NCP720BMT135TBG is its ability to provide ripple rejection of more than 45 dB at 10 kHz. This means that the output voltage will remain stable and consistent even in noisy environments. This level of performance makes it ideal for applications such as automotive, video and ADC circuit designs, where noise rejection is paramount.

The working principle of the NCP720BMT135TBG is quite simple. When the output voltage drops below the set point, the error amplifier senses the difference and signals the power transistor to reduce the voltage drop across the series regulator. As the output voltage approaches the set point, the error amplifier reduces the signal to the power transistor, which in turn reduces the overall current output. This simple feedback loop ensures that the output voltage remains stable and consistent even when the load or input voltage changes.

The NCP720BMT135TBG is well suited for various applications in the industrial, automotive and consumer electronics industries. On top of its excellent voltage regulation performance, it also has a low quiescent current and a low dropout voltage. All of these features make the NCP720BMT135TBG an ideal choice for designers looking for a reliable and efficient voltage regulator.
