The NCP4587DSN12T1G is a low dropout regulator (LDO) designed to provide precise low dropout voltage and precise output voltage. It has an output current of 1.5A and comes in a three-pin package. The NCP4587DSN12T1G features a ground-sense pin and a highly integrated, wide voltage range bipolar regulator. The ground sense pin can be used as a reference to set the output voltage and as an input for thermal shutdown. The ShutDown pin can be used to disable the output, or the output can be set to fixed values by means of external resistors.

The NCP4587DSN12T1G is typically used in automotive, industrial and consumer electronics applications where precise output voltage regulation is required. It is suitable for use in applications such as automotive infotainment systems, automotive control units, and other electronic products with power supplies needing very precise voltage regulation.

The NCP4587DSN12T1G offers low dropout capability, allowing it to operate with very low input voltages, up to 7 V, while still providing an accurate output voltage and maintaining an input voltage of a fraction of a volt above the regulator’s output voltage. This allows the device to provide a very precise output voltage, even when operating at very low power supply rail voltages, helping to minimize system power consumption.

The NCP4587DSN12T1G offers significant advantages for power supply design since its high output voltage accuracy is maintained over line and temperature variations. This precision is made possible by the incorporation of a current divided reference, which allows higher voltage adjustments with low tolerance and very low temperature coefficients. As a result, the device provides better system stability and output control, while at the same time reducing the area required for PCB traces as well as external components.

The NCP4587DSN12T1G’s internal circuitry is designed to provide a very low output noise, thereby avoiding interference with sensitive loads connected to the device’s output. Additionally, the output current limit protection feature helps ensure system safety by preventing the device from delivering an excessive amount of current in overload situations.

With a wide input voltage range of 4.3 V to 7 V, and an output voltage range from 0.8 V to 6 V, the NCP4587DSN12T1G is ideal for powering a wide range of applications. The device has a maximum output current of 1.5 A, with a dropout voltage of 105 mV. It is available in a 3-pin TSSOP package with standard operating conditions from -40 °C to +85 °C.

The NCP4587DSN12T1G is an ideal choice for applications requiring a precise and efficient low dropout regulator. Its low dropout capability, wide input voltage range, precise output voltage regulation, and wide temperature range make it an excellent choice for a variety of applications.
