X60003CIG3Z-41 is a voltage reference from the PMIC - Voltage Reference class. It is a dual power supply, low dropout (LDO) regulator with an output of 3.3Vdc, ideal for supplying the very low current to ESD sensitive devices. The voltages are individually preset and can be adjusted by the user.

The application field of X60003CIG3Z-41 extends from industrial communication, such as buses and bridges, to consumer applications, including digital TV and gaming devices. This voltage reference is also suitable for supplying microcontrollers, FPGAs, and other digital circuits with a reliable, consistent voltage. Additionally, X60003CIG3Z-41 can be used to power any number of low voltage devices, such as Li-ion battery management and LED backlighting, where low supply current and fast transient response are required.

The important features of the X60003CIG3Z-41 are its ultralow operating voltage, low dropout voltage, 1.5µV/V line regulation, and 0.8µV/V load regulation. Its input voltage range is 0.8V to 5.5V, and its maximum output voltage is fixed at 3.3V. The X60003CIG3Z-41 also has an adjustable current limit, thermal protection, and short circuit protection.

The X60003CIG3Z-41 has a two-stage design, which helps to provide a fast response to loading changes. In the first stage, the LDO regulator is configured to supply a fixed output voltage and presents a low impedance source of current to the load. In the second stage, the load is regulated by the LDO to maintain a steady output voltage irrespective of changes in the load current.

The LDO of the X60003CIG3Z-41 uses a PNP pass transistor and an NPN series pass transistor to regulate the output voltage. This combination is referred to as a series-pass configuration, and it allows the voltage regulator to efficiently regulate the output voltage. The PNP pass transistor controls the voltage drop across the series pass transistor, which in turn controls the output current. As the load current increases, the series pass transistor increases the voltage drop across it, thereby reducing the output current.

The key feature of X60003CIG3Z-41 is its use of an adjustable current limit, which prevents it from providing more current than the load requires, thus preventing over-current protection. The current limit is adjustable, so that it can be set to provide the desired level of protection. In addition, the LDO features thermal protection and short-circuit protection to prevent the device from being damaged by overloads.

The X60003CIG3Z-41 is designed to offer comprehensive protection from over-voltages, over-currents, and other undesirable conditions. The voltage reference device is protected against over-voltage and over-current conditions by its adjustable current limit. Additionally, it is protected from excess temperatures by its thermal shut down protection. These protections ensure that the X60003CIG3Z-41 is able to provide reliable and consistent performance.

All in all, the X60003CIG3Z-41 from PMIC - voltage reference class is an excellent voltage reference device for a wide range of applications. It combines low dropout performance with adjustable current limit, thermal protection, and short-circuit protection, making it an ideal choice for suppressing high-current loads, while providing reliable output voltage regulation.
