NCV86603BD50R2G is a kind of integrated low drop-out (LDO) linear regulator with a very low input voltage threshold, making it suitable for a wide variety of low voltage applications. It is designed for applications that require precise regulation and low dropout voltage operation. The device features an eight-pin low voltage (1.8 V to 5.5 V) package, with an integrated voltage reference, current limit, reverse current protection and short-circuit protection.

The NCV86603BD50R2G provides high efficiency, low quiescent current, adjustable current limit and output voltage monitoring, making it suitable for applications such as active real-time clock supply, general purpose linear regulators with low dropout, flash memory, CP/M memory, adjustable power supplies and other low voltage applications.

Application fields
NCV86603BD50R2G is appropriate for power management applications involving general-purpose linear regulation and reverse energy protection, such as active real-time clock supply, low voltage general purpose linear regulators with low dropout, flash memory, CP/M memory, and adjustable power supplies.

Working Principle
NCV86603BD50R2G utilizes an on-chip low dropout linear regulator to convert a higher supply voltage VIN to a lower regulated regulated voltage VOUT as specified by the user. The output voltage of the device is adjustable from 1.8 V to 5.5 V, with a maximum load current of 1 A and a minimum load current of 50 mA.

The device has an integrated current sense amplifier for current limit protection, as well as open-drain current limit protection, short-circuit protection, reverse current protection, thermal shutdown and dropout status output. In addition, the device can enter power-saving sleep mode when the load current drops below the internally preset threshold.

The regulated output voltage is regulated by an internal control circuit, which compares the output voltage VOUT with an internal voltage reference. The error amplifier in the control circuit amplifies the difference between the voltage reference and VOUT so as to adjust the output current source Vg in order to maintain the VOUT constant.

NCV86603BD50R2G also has an adjustable current limit and soft-start capability. The current limit is adjustable between 50 mA and 1 A with a single-pin configuration. During soft-start, the output voltage increases slowly to minimize inrush current and to limit transient response during start-up.
