NCP698SQ25T1G application field and working principlePMIC - Voltage Regulators - LinearPower management integrated circuits (PMICs) are electrical circuits used to manage the power of a circuit, usually consisting of several distinct voltage regulators and MOSFET power switches, among other components. NCP698SQ25T1G is a type of low-dropout (LDO) voltage regulator, in which the output voltage Vout is regulated by varying the voltage difference between its input voltage Vin and output voltage Vout, in such a way that it drops only a predetermined and specified amount when Vout increases or decreases. NCP698SQ25T1G is a linear regulator with a low operating current of 0.5 mA, making it a good choice for applications that require low power consumption. It has a maximum output voltage of 25V and a maximum input voltage of 38V. Its features include overload and short circuit protection, adjustable output voltage, and wide temperature range of full load operation. This voltage regulator also has a fast transient response, which makes it ideal for applications requiring high bandwidth such as audio and video processing.NCP698SQ25T1G is mainly used in consumer electronics, automotive, and industrial applications. It meets various automotive standards such as AEC-Q100, AEC-Q101 and SAE J1113. It is ideal for automotive applications because of its low dropout voltage and wide temperature range. It is suitable for consumer electronics applications such as portable consumer, handheld and switching power supplies, personal computers, and consumer audio and video products. It is also an ideal choice for industrial applications, where high efficiency and low power consumption are required.In terms of its working principle, the input voltage Vin is applied across the input line of the voltage regulator, whereas the output voltage Vout is applied across the output line. The reference voltage is generated across the reference voltage line and is used to compare the difference between the input and the output. When the difference between the input and the output increases, the transistor on the output line is switched on, thus pulling the output voltage down. On the other hand, when the difference between the input and the output decreases, the transistor is switched off and the output voltage increases. This is how NCP698SQ25T1G maintains the output voltage within its predetermined range.In summary, NCP698SQ25T1G is a linear voltage regulator with a low operating current of 0.5 mA and maximum output voltage 25V. It is mainly used in consumer electronics, automotive, and industrial applications and meets various automotive standards. Its working principle is based on comparing the difference between the input and the output, and adjusting the output voltage accordingly.
