Overview
The ADP7104ACPZ-5.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 3.3 V to 20 V and provides up to 500 mA of output current. This specific variant features a fixed 5.0 V output with an initial accuracy of ±0.8%. The device delivers low noise performance, specified at 15 µV rms for the fixed output version, and includes reverse current protection. It maintains stability with small 1 µF ceramic output capacitors.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes reverse current protection to prevent backflow
- Features user-programmable precision undervoltage lockout via the enable pin
- Integrates foldback current limit and thermal overload protection
Applications
- Regulation for ADC and DAC circuits
- Precision amplifiers and high frequency oscillators
- Clocks and PLLs in communications infrastructure
- Medical and healthcare equipment power supplies
Procurement Notes
Verify the package type matches the required PCB footprint, as the component is available in both LFCSP and SOIC configurations. Confirm that the fixed 5.0 V output specification aligns with the system design requirements. Ensure that the input voltage range and load conditions remain within the absolute maximum ratings defined in the datasheet to maintain reliability.
Selection Notes
Select this component when a high input voltage range up to 20 V is required alongside low noise performance. It is suitable for applications needing precise fixed voltage regulation without external feedback dividers. Consider the thermal resistance characteristics if operating near maximum load currents or elevated temperatures.
Part Context
This part belongs to the ADP7104 family of low dropout regulators designed for high-performance analog and mixed-signal circuits. The series offers multiple fixed output voltage options and an adjustable version. The ACPZ suffix indicates the specific package and temperature grade configuration used in this ordering code.
Replacement Considerations
Check for other ADP7104 variants with different fixed output voltages if the system requires a different rail. Verify compatibility with evaluation boards such as the ADP7104RDZ-REDYKIT for prototyping purposes.
