Working Principle

The NCP4687DSN28T1G is a linear voltage regulator which works by regulating the output voltage of a power supply circuit in order to ensure that the voltage remains constant irrespective of variations in the input voltage. The regulator also ensures that the output current remains within specified ranges. It is designed to provide a stable reference voltage from either an AC or DC source. The core of the voltage regulator is an integrated voltage reference, error amplifier, and pass transistor.

The error amplifier is the heart of the regulator and is responsible for comparing the voltage setpoint with the output voltage and providing a signal proportional to the difference between the two. The pass transistor is then used to control the output voltage by varying the current to the load. When the reference voltage and output voltage are equal, the pass transistor will be conducting regardless of the load current and the voltage will remain constant. The NCP4687DSN28T1G offers high precision voltage regulation with a low dropout voltage, a wide operating temperature range, and low quiescent current.

The NCP4687DSN28T1G is a highly efficient Low Drop Out (LDO) linear voltage regulator. It offers high performance and low quiescent current with high accuracy. The NCP4687DSN28T1G is suitable for many applications such as stepping down from a higher voltage to a lower voltage in automotive, medical, telecom, computing, and industrial applications.
