PMIC (Power Management Integrated Circuit) is a controller used in power management applications. It provides various functions to control, regulate and monitor voltage. The linear voltage regulator circuits are generally used for regulation, filtering and conversion of power supply states. This type of regulator circuit is generally used for voltage regulation, power supply noise suppression, and voltage conversion. ADP162AUJZ-2.8-R7 is a linear voltage regulator integrated circuit, designed for medium current and medium voltage applications, with enhanced stability and low noise characteristics.

The ADP162AUJZ-2.8-R7 is a slightly modified version of the ADP162AUJZ-2.8. It is a positive voltage regulator which delivers a stable output voltage of 2.8V, while offering a voltage current range of 1A to 5A. In addition to the standard features such as built-in input capacitors and EMI Filter, the ADP162AUJZ-2.8-R7 features an enhanced stability architecture, with a lower output voltage tolerance (±0.5%) and lower output noise (3mV RMS). The regulator also offers reverse current protection and a low-bias current start-up.

The ADP162AUJZ-2.8-R7 is ideal for applications such as consumer electronics, automotive applications, memory cards, USB/HDMI interface, industrial equipment and other high current applications. It offers a wide operating temperature range (-40°C to +125°C) and is capable of operating from a wide input voltage range (2.5V to 5.5V).

The key features of the ADP162AUJZ-2.8-R7 include:

• Wide input voltage range (2.5V to 5.5V)
• High current capability (1A to 5A)
• Stable output voltage accuracy of ±0.5%
• High efficiency (up to 95%)
• Line and load regulation of 0.03%/V and 0.1%, respectively
• Low noise (3mV RMS)
• Low reverse current protection
• Reverse bias safe
• Output short-circuit protection
• Low start-up current

The ADP162AUJZ-2.8-R7 is a highly reliable and efficient regulator for a wide range of applications. As the linear regulator circuit is designed for constant voltage output, the internal circuitry of the chip consists of an operational amplifier and other active components, like a diode and zener diode connected in a feedback loop. The voltage fed back to the non-inverting input terminal of the operational amplifier is compared with a reference voltage, and the output is adjusted to maintain the reference voltage at the non-inverting input terminal. This error amplifier ensures that the output voltage remains constant, regardless of the changes of input voltage or load current.

The ADP162AUJZ-2.8-R7 also features internal overload protection. When excessive current flows through the device, it will shut down the output and protect both the IC and the application. This is just one of the many advantages of the ADP162AUJZ-2.8-R7, which is why it is so popular with power management applications.

Overall, the ADP162AUJZ-2.8-R7 linear voltage regulator is an excellent choice for medium voltage and current applications. Its enhanced stability, low noise, wide input voltage range, high efficiency, reverse current protection, and overload protection features make it a versatile and reliable regulator circuit, suitable for a wide range of applications.
