Overview
The ADP7183ACPZN2.5-R7 is a negative-output low dropout linear regulator from Analog Devices, housed in an 8-lead LFCSP package. It delivers up to -300 mA of output current with a fixed output voltage of -2.5 V. The device operates within an input voltage range of -2.0 V to -5.5 V and maintains an operating junction temperature between -40°C and +125°C. Key electrical characteristics include a typical power supply rejection ratio of 75 dB at 10 kHz and an integrated output noise of 4 μV rms across the 100 Hz to 100 kHz bandwidth.
Feature Summary
- Provides ultralow output noise independent of the selected output voltage setting
- Delivers high power supply rejection ratio performance across a wide frequency spectrum
- Features flexible enable logic compatible with both positive and negative control signals
- Integrates comprehensive protection mechanisms including current limiting and thermal overload shutdown
Applications
- Power regulation for analog-to-digital converters (ADCs)
- Power regulation for digital-to-analog converters (DACs)
- Supply conditioning for precision amplifiers
- Noise-sensitive circuits in communications infrastructure
- Power management in medical and healthcare instrumentation
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the ACPZN variant corresponds to the specified LFCSP package dimensions. Ensure compatibility with the required negative voltage rail specifications before finalizing procurement orders.
Selection Notes
Select this component for applications requiring stable negative voltage rails with minimal noise interference. Evaluate the thermal resistance requirements based on the expected load current and ambient conditions. Consider the startup time implications if external capacitors are added to the feedback network.
Part Context
This part belongs to the ADP7183 family of complementary metal oxide semiconductor low dropout regulators. The series is designed for high-performance mixed-signal circuits requiring precise negative voltage regulation. The specific model provides a fixed -2.5 V output option within the broader adjustable and fixed voltage lineup.
Replacement Considerations
Direct replacements within the same family include other fixed voltage options such as ADP7183ACPZN3.3-R7 or ADP7183ACPZN1.5-R7. Verify pinout compatibility and ensure the alternative part number meets the specific -2.5 V requirement without necessitating circuit redesign.
