Overview
The ADP7182ACPZ-5.0-R7 is a CMOS, low dropout (LDO) linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of −2.7 V to −28 V and provides up to −200 mA of output current. The device features a fixed output voltage of −5 V with an initial accuracy of ±1%. It delivers low noise performance of 18 μV rms and high power supply rejection ratio (PSRR). The regulator is stable with small 2.2 μF ceramic output capacitors and includes current-limit and thermal overload protection.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Supports positive or negative enable logic for flexible control
- Stable with small ceramic output capacitors
- Includes current-limit and thermal overload protection
Applications
- Regulation to noise-sensitive applications
- Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits
- Precision amplifiers
- Communications and infrastructure systems
- Medical and healthcare equipment
Procurement Notes
Verify the specific package type and suffix against the manufacturer's official ordering guide before procurement. Confirm that the −5 V fixed output variant matches the system requirements. Ensure compatibility with the required input voltage range and load current specifications. Check for any recent revisions to the datasheet that may affect pin configurations or electrical characteristics.
Selection Notes
Select this component when a negative voltage rail is required with low noise and high PSRR. Ensure the input voltage does not exceed the maximum rating of −28 V. Verify that the PCB layout supports the necessary thermal dissipation for the LFCSP package. Consider the startup time and shutdown current if power management is critical.
Part Context
The ADP7182 series is designed for high-performance analog and mixed-signal circuits operating from −27 V down to −1.2 V rails. It utilizes an advanced proprietary architecture to achieve excellent line and load transient response. The series is available in multiple packages including 6-lead and 8-lead LFCSP and 5-lead TSOT.
Replacement Considerations
Consult the official Analog Devices replacement matrix for verified substitutes. Cross-reference pinouts and electrical specifications carefully. Ensure any alternative component meets the same noise and PSRR requirements.
