Overview
The ADP7104ARDZ-9.0-R7 is a CMOS low dropout linear regulator providing a fixed 9 V output with up to 500 mA current capability. It operates from an input voltage range of 3.3 V to 20 V and features low noise performance of 15 µV rms. The device includes reverse current protection, programmable UVLO, and a power-good indicator. It is available in 8-lead LFCSP and SOIC packages.
Feature Summary
- Provides high power supply rejection and low noise for sensitive analog circuits
- Includes reverse current protection and thermal overload safeguards
- Features user-programmable undervoltage lockout and power-good status indication
Applications
- Regulation for ADC and DAC circuits
- Precision amplifiers and high frequency oscillators
- Clocks and PLLs
- Communications and infrastructure systems
- Medical and healthcare equipment
Procurement Notes
Verify the specific package type (LFCSP or SOIC) and tape-and-reel quantity against the manufacturer's ordering guide. Confirm that the component meets RoHS compliance requirements for your target market. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the CMOS internal circuitry.
Selection Notes
Select this part when a stable 9 V rail is required from higher voltage sources up to 20 V. Consider the 350 mV dropout voltage at full load to ensure sufficient headroom. Evaluate thermal dissipation based on the selected package and PCB layout to maintain junction temperature within specified limits under maximum load conditions.
Part Context
This component belongs to the ADP7104 family of low noise CMOS LDO regulators designed for high-performance mixed-signal applications. The series offers multiple fixed voltage options alongside an adjustable variant, all sharing common architectural benefits such as stability with small ceramic capacitors and robust protection features.
Replacement Considerations
Direct substitutes include other ADP7104 variants with different fixed output voltages if the voltage level can be adjusted via external components using the adjustable version.
