Overview
The ADP7182AUJZ-2.5-R7 is a negative voltage linear regulator from Analog Devices, operating within an input range of −2.7 V to −28 V and delivering up to −200 mA output current. It provides a fixed −2.5 V output with ±1% initial accuracy at 25°C. The device features low noise performance of 18 μV rms and high power supply rejection ratio (PSRR) of 66 dB at 10 kHz. It operates with a low quiescent current of 650 μA under full load and includes current-limit and thermal overload protection.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Features enable logic compatible with positive or negative control signals
- Maintains stability using small ceramic output capacitors
- Includes integrated current-limit and thermal shutdown protection
Applications
- Powering analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits
- Supplying precision amplifiers in instrumentation systems
- Regulating noise-sensitive sections in communications infrastructure
- Providing stable rails for medical and healthcare equipment
Procurement Notes
Verify the specific package type matches your design requirements, as the ADP7182 series is available in multiple configurations including TSOT and LFCSP. Confirm that the ordering suffix corresponds to the desired reel quantity and tape specifications. Ensure compatibility with your PCB footprint by checking the outline dimensions provided in the datasheet before finalizing procurement.
Selection Notes
Select this component when designing systems requiring negative voltage regulation from high input rails down to low voltage levels. It is appropriate for applications needing low noise and high PSRR to protect sensitive signal chains. Consider the thermal resistance characteristics and board layout constraints if operating near maximum load currents or ambient temperatures.
Part Context
This part belongs to the ADP7182 family of CMOS low dropout linear regulators designed for high input voltage applications. The series supports both fixed and adjustable output voltages, catering to diverse system architectures. It is engineered to replace older discrete solutions or less efficient switching regulators in space-constrained designs requiring clean power delivery.
Replacement Considerations
Direct replacements include other ADP7182 variants with different output voltages or packages, such as ADP7182ACPZN-2.5R7. Verify pinout compatibility and thermal performance when substituting between package types like TSOT and LFCSP.
