PMIC - Voltage Regulators - Linear

The NCP4624DSN50T1G is a quad low-noise linear voltage regulator from ON Semiconductor, part of its specialty linear voltage regulator family. It features an adjustable output voltage range of 0.8V to 9V, a positive temperature coefficient of 0.004% V/V/°C, an output current of 1A, and a low dropout of 260mV at full load. It also has low quiescent current and low operational noise. The NCP4624DSN50T1G is used in automotive and other demanding applications. It is a pin-compatible drop-in replacement for the industry standard TLE2426 rail-splitter.

The NCP4624DSN50T1G uses a common sense regulation architecture to provide adjustable voltage regulation to four voltage outputs. It uses an open loop NPN/N-channel output stage and an adjustable voltage reference to achieve its regulation to provide high accuracy and repeatability over temperature and supply variations. The four output pins are current limited and relatively immune from voltage transient. To provide these features, the device includes an internal temperature sensor, an active current source, a fault detector, and an adjustable voltage reference.

The adjustment of the voltage reference can be used to set the output voltage for the particular application. The voltage reference can be set by using the external resistor Rset and the internal reference pin. The voltage reference can also be programmed by using an external voltage reference bypassing Rset. There is an operating range of 0.8V to 9V with accuracy of ±1mV.

The NCP4624DSN50T1G is designed to withstand supply voltage transients up to 65V. It has a quiescent current of only 550µA and a low dropout voltage of 260mV at 3 A. The device provides a fast current limit of 1µs. This makes it suitable for noise-sensitive applications. Furthermore, the device features Input Undervoltage Lockout (UVLO) for increased safety.

The NCP4624DSN50T1G is an ideal device for automotive, industrial, communications, and other demanding applications. It is available in a 5-pin TSOT package and is specified over an extended temperature range of -20°C to 150°C.
