The ZRT050GC1TA is a voltage reference that falls into the Power Management Integrated Circuit (PMIC) family. It is a monolithic four-terminal series regulator that is specifically designed for low input and output voltage applications. The ZRT050GC1TA is therefore greatly suited for use in many portable and hand-held devices such as cell phones, PDAs, digital cameras, pagers and two-way radios.

The ZRT050GC1TA works by utilizing a PNP current source, coupled with an adjustable series pass transistor (current limiter) to provide a precise and regulated output voltage. The device starts up in current-mode operation, with the PNP current source controlling the amount of current flowing through the pass transistor. The current-mode operation is then adjusted via an external input voltage, allowing the reference voltage to maintain a precise setting that is both stable and independent of temperature.

The ZRT050GC1TA is an ideal solution for applications where highly accurate, low power, and stable voltage regulation is needed. Its four-terminal configuration provides high precision and tight regulation, making it suitable for various battery-operated systems, as well as other portable equipment powered from an AC adapter. It can also be used in light-load applications, as the device is designed to remain in current-mode operation even under low load conditions.

The ZRT050GC1TA features several protection features that ensure safe and reliable operation. It is designed to prevent over-voltage, over-current, and thermal runaway conditions that could potentially damage the device. It also features over-temperature protection, which will reduce the device’s output current so that the junction temperature is maintained within the safe operational range.

The ZRT050GC1TA is designed to offer a wide range of applications from low input and output voltages, low noise, up to a maximum operating temperature of 125°C. With its small size, low power requirement and stable operation, the ZRT050GC1TA can provide a consistent, reliable performance for a variety of portable and hand-held applications.
