PMIC - Voltage Regulators - Linear: NX1117CE50Z,115 Application Field and Working Principle

The NX1117CE50Z is a voltage regulator IC (integrated circuit), specifically a Low Dropout (LDO) linear regulator. It is a three-terminal regulator, meaning that it only accept input from the input and ground pins, and output at the output pin. It is part of an on-chip system featuring low quiescent current. This IC is designed to work in a wide range of applications, such as clock supplies, voltage conversion, and power control, among others.The NX1117CE50Z operates in a wide input voltage range, from 1.3 V to 6 V, and can output regulated output voltages between 0.7 V to 5.5 V. It usually requires a small amount of input or output capacitance to ensure adequate noise filtering, so it can easily be used in applications that require smooth, low-noise operation. Maximum current with minimum temperature rise can be achieved with proper board layout and by sizing the IC according to the load requirements.At the heart of the device is a transistor-based series pass regulator that regulates the output voltage. It is important to note that outputs of this type of ICs have a maximum minimum voltage dropout of typically 0.2 V to 0.5 V. This means that, in order to be able to regulate a given output voltage, the input voltage must be higher by at least the given dropout voltage.The IC is also able to deliver very good efficiency in all applications, thanks to its high-gain, low voltage, and low-noise, operational amplifier architecture. For example, the quiescent supply current in the typical application is around 1 mA, which allows for the very efficient delivery of current in low-power applications. The device also features several protection features, such as thermal overload protection and short-circuit protection, to help ensure that it is always operating safely under all conditions.In summary, the NX1117CE50Z is a low-dropout linear voltage regulator IC that supports a wide range of applications. It provides a smooth, low-noise regulation with excellent efficiency, and offers several protection features for safety. This makes it an ideal choice for many applications where low-cost, low-noise, and high-efficiency voltages regulation is needed.
