Overview
The ADP7104ACPZ-3.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., providing a fixed 3 V output with up to 500 mA of current capability. It operates from an input voltage range of 3.3 V to 20 V and features a typical quiescent current of 900 μA at full load. The device offers a low dropout voltage of 350 mV at 500 mA, initial accuracy of ±0.8%, and reverse current protection. It includes programmable undervoltage lockout, power-good indication, and foldback current limit with thermal overload protection.
Feature Summary
- Low noise performance with 15 µV rms output noise for fixed versions
- High power supply rejection ratio of 60 dB at 10 kHz
- Stable operation with small 1 µF ceramic output capacitors
- Integrated reverse current protection and user-programmable precision UVLO
Applications
- Regulation for ADC and DAC circuits
- Precision amplifiers and high frequency oscillators
- Clocks and PLLs in communications and infrastructure
- Medical and healthcare equipment
- Industrial and instrumentation systems
Procurement Notes
Verify the specific suffix -R7 indicates tape and reel packaging when sourcing components. Confirm that the ACPZ variant corresponds to the LFCSP package type required for your design. Ensure compatibility with the 3 V fixed output specification before finalizing procurement orders.
Selection Notes
Select this component for applications requiring low noise regulation from higher voltage rails down to 3 V. Consider the 350 mV dropout voltage at maximum load when determining minimum input voltage requirements. Evaluate thermal dissipation based on the difference between input and output voltages multiplied by the load current.
Part Context
This part belongs to the ADP7104 family of 20 V, 500 mA low noise CMOS LDO regulators. The family provides multiple fixed output voltage options including 1.5 V, 1.8 V, 2.5 V, 3 V, 3.3 V, 5 V, and 9 V, alongside an adjustable version. The ADP7104ACPZ-3.0-R7 specifically delivers the 3 V fixed output option in the compact 8-lead LFCSP package.
Replacement Considerations
Direct substitutes within the same family include other fixed voltage variants such as ADP7104ACPZ-3.3-R7 or ADP7104ACPZ-1.8-R7 if different output levels are acceptable. For adjustable output needs, the ADP7104ACPZ-ADJ-R7 can be used with external resistors.
