The NX1117CE25Z,115 is a low dropout linear regulator from Nexperia, and it belongs to the category of PMIC (power management integrated circuits). Designed to be used in applications that have limited supply of Power, in situations where the input voltage is slightly higher than the voltage that needs to be regulated. The Z1117CE25Z,115 belongs to the voltage regulator type - linear.

The primary purpose of the Z1117CE25Z,115 is to act as an adjustable source of lownoise power for various applications, such as telecom equipment, computer peripherals, automotive electronics, and industrial process control. It has an operating temperature range of -40 ° C to +85 ° C, making it ideal for applications requiring temperature compensation. The device offers very low quiescent current, low dropout voltage and excellent transient response.

The Z1117CE25Z,115 utilizes a low dropout linear regulator architecture to achieve efficient regulation of input voltage in the range of 4.375V to 17V, coupled with output voltage accuracy of +/-2%. The integrated low dropout regulator (LDO) features a very low quiescent current of 8uA at light load and reaches a maximum of 100mA when operating at full rated output current. The circuit is protected against short circuit, current limit and thermal overload. The device also includes an enable control pin, allowing the oscillator to be powered down, resulting in a very low current drain condition of 22uA.

The device consists of a bandgap reference, an error amplifier, a power MOSFET switch and a series resistor. The bandgap reference establishes the voltage set point and provides a temperature compensated reference voltage. The error amplifier compares the two input voltages, the adjustable reference and feedback voltages, and generates a control signal for the MOSFET switch. The output load is regulated by the power MOSFET switch which is connected to the reference resistor, and the output is regulated by a series of feedback loops and compensators.

The Z1117CE25Z,115 is capable of providing efficiency of up to 85%. The device can be used in applications such as processor core power supplies and embedded microcontroller power supplies. It is also suitable for industrial and automotive applications, including automotive battery management and equipment powered by 24V DC sources, allowing designers to use the device over a wide temperature range of -40°C to +85°C.

In conclusion, the Nexperia Z1117CE25Z,115 is a low dropout linear regulator that can be used for various application fields. Its low quiescent current, low dropout voltage and excellent transient response make it an ideal choice for many applications. The device is capable of providing efficiency of up to 85%, and it can be used in applications such as processor core power supplies, embedded microcontroller power supplies, battery management, and equipment powered by 24V DC sources.
