The ADP165ACBZ-1.8-R7 voltage regulator is a type of linear voltage regulator categorized under power management integrated circuits (PMIC). This particular voltage regulator falls within the group of devices designed for general purpose applications. It provides a regulated output voltage of 1.8 volts and features an input voltage range of up to 7 volts.

Linear voltage regulators are devices that keep the output voltage at a stable, constant level as the load varying. This is accomplished through voltage or current regulation. In either case, a feedback loop is established between the output and the input. This loop dynamically adjusts the output voltage so that, even when various loads are applied, it remains constant.

The ADP165ACBZ-1.8-R7 is a special purpose linear voltage regulator specifically designed for applications where an input voltage of 7 volts is available and an output of 1.8 volts is desired. The device’s internal operation is based on the modified-constant-voltage series voltage regulator principle. At its heart, the ADP165ACBZ-1.8-R7 employs a common emitter-like circuit as its power output stage.

The circuit’s output characteristics are primarily determined by the load current and the load resistance connected to its output terminal. Response time to a load varies from 0.02 to 100 microseconds depending on the value of the load resistance.

The device’s power dissipation capability is limited by its power dissipation capability. It has a power dissipation rating of 420 mW when mounted onto an alumina ceramic substrate and a rating of 80 mW when mounted onto an FR-4 substrate. With regard to its thermal characteristics, the device has a thermal resistance junction-to-ambient of 6.8°C/W when mounted onto an alumina ceramic and a thermal resistance junction-to-ambient of 12°C/W when mounted onto an FR-4.

The ADP165ACBZ-1.8-R7 comes with an integrated enable pin. This pin enables or disables the device depending on the logic state applied to it. When enabled, the device’s power-on output voltage is available at the output terminal; when disabled, the output voltage is shut off.

In terms of its electrical characteristics, the ADP165ACBZ-1.8-R7 comes with an output current of up to 50 mA. Additionally, the device exhibits a typical line regulation of 0.1%/V and a typical load regulation of 0.8%/mA. The device’s output noise is typically in the region of 50 microvolts.

The ADP165ACBZ-1.8-R7 voltage regulator is ideal for low-voltage and low-power applications. It is typically used to power microcontrollers, logic chips, LCD drivers, as well as other low-power applications. The device is available in a compact SOT-89 package (3x3 mm).
