The ZR40402N850TA is a Voltage Reference device from the PMIC (power management) family. It belongs to the Zener Diode Voltage Regulator type and it is designed to stabilize the output voltage of a power supply or other circuit. Its main purpose is to limit the output voltage of the voltage regulator in order to maintain reliable and stable supply within enclosed or regulated power systems. The device uses a metal-oxide-semiconductor field-effect transistor (MOSFET) structure to achieve high current output with low voltage drop.

In a typical application, the ZR40402N850TA negative voltage regulator will be connected to the power supply’s input voltage line. It is designed to ensure the output voltage is always held within a predetermined range, even if the input voltage fluctuates. Thanks to its highly integrated structure, it can provide excellent performance under low-power conditions and low supply line noise, compared to other voltage reference types. Additionally, it has a wide operating temperature range and can withstand a variety of battery currents and voltage profiles.

The working principle behind the ZR40402N850TA is based on the dual control architecture. When the input voltage is greater than the reference voltage, the current provided by the device will be greater than the threshold current, causing the output voltage to drop. On the other hand, when the input voltage is smaller than the reference voltage, the current will be less than the threshold current and the output voltage will rise.

The ZR40402N850TA voltage reference has several key features. It offers a very precise and low-drift voltage regulation (-200 to +700 mV) for precise and reliable operation. Additionally, it has a maximum tolerance of 100 mV to ensure a high degree of accuracy over a wide inductance range. It is also capable of providing a wide operating temperature range (-40 to +85 °C). Lastly, it has low power consumption (1.2 W maximum) and is optimized for low self-heating.

The ZR40402N850TA voltage reference is used in various applications including automotive, industrial, military, and power management applications. It can be used to provide a stable output voltage for switching power supplies and to stabilize the output voltage of a generator’s output voltage. Additionally, it can be used in battery charging/discharging circuits and for reliable performance under widely varied conditions. In summary, the ZR40402N850TA voltage reference is a reliable and precise voltage regulator suitable for a wide range of applications.
