Linear voltage regulator integrated circuits (ICs) are commonplace in consumer and industrial electronics, providing a stable DC power supply function. The ADP162AUJZ-1.8-R7 is an example of such a linear voltage regulator IC. Its uses and working principle will be explored in detail here.

The ADP162AUJZ-1.8-R7 is a positive 15V output, low-dropout voltage regulator IC. It has two primary application fields - firstly in fixed-voltage, general-purpose regulation, and secondly in battery-operated applications, as a complete, low-voltage DC power supply. In either role, its 15V output provides a reliable, stable DC power supply.

The working principle of the ADP162AUJZ-1.8-R7 is based on an open-loop difference amplifier. It has a single-ended input, connected to a reference voltage, and a dual-ended input, connected to a reference voltage and the output voltage. Through differencing this input voltage, the ADP162AUJZ-1.8-R7 supplies an output that is always equal to the reference voltage.

The ADP162AUJZ-1.8-R7 boasts a wide operating temperature range of -40°C to +125°C and a wide input voltage range of 3V to 32V. It features a high power-supply ripple rejection, low output noise and excellent line and load regulation. The IC is also equipped with a low dropout voltage (1V), a low quiescent current (<45μA) and optional enable control.

The ADP162AUJZ-1.8-R7 also provides comprehensive protection against over-current, reverse current, short-circuit and thermal overload conditions. An internal current limiting feature kicks in automatically to reduce the power dissipation when the IC is overheating. An external shutdown facility can also be used to further limit the power dissipation by disconnecting the supply in high-power conditions.

The ADP162AUJZ-1.8-R7 is a useful tool for applications that require a reliable, stable low-voltage DC power supply. Its combination of features, flexibility and protection make it ideal for use in a variety of applications. Its uses in fixed-voltage and battery-operated applications make it a highly sought-after linear voltage regulator IC.
