Overview
The ADP7104ARDZ-2.5-R7 is a fixed-output low dropout linear regulator providing 2.5 V at up to 500 mA from a 3.3 V to 20 V input range. It features 15 µV rms output noise and reverse current protection. The device operates with a minimum 1 µF ceramic capacitor, offering line regulation of ±0.015 %/V and load regulation of 0.2 %/A. Quiescent current is 900 µA at full load, with shutdown current below 40 µA. It includes programmable UVLO, power-good indication, and foldback current limit.
Feature Summary
- Low noise performance suitable for sensitive analog circuits
- Reverse current protection prevents backflow when output exceeds input
- Programmable undervoltage lockout enables precise power sequencing
- Power-good indicator provides digital status monitoring
Applications
- ADC and DAC circuit regulation
- Precision amplifier power supplies
- High frequency oscillators and clock circuits
- PLL power management
Procurement Notes
Verify the specific suffix -R7 indicates reel packaging configuration. Confirm the ARDZ designation corresponds to the SOIC package variant rather than LFCSP. Ensure the 2.5 voltage rating matches the required system rail before integration.
Selection Notes
Select this component for applications requiring high PSRR and low noise in mixed-signal environments. Verify that the input voltage remains within the 3.3 V to 20 V operational window. Ensure the PCB layout supports the thermal requirements for 500 mA loads using the specified SOIC footprint.
Part Context
This part belongs to the ADP7104 family of CMOS LDO regulators designed for high-performance analog and mixed-signal circuits. The series offers multiple fixed voltage options and an adjustable version, all sharing the same core architecture for low noise and high power supply rejection.
