Overview
The ADP7104ACPZ-1.8-R7 is a CMOS low dropout linear regulator providing a fixed 1.8 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, power-good indication, and user-programmable undervoltage lockout. It utilizes an 8-lead LFCSP package for compact thermal management.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes reverse current protection to prevent backflow
- Features programmable undervoltage lockout for sequencing control
- Offers digital power-good status indicator
Applications
- ADC and DAC circuit regulation
- Precision amplifier power supplies
- High frequency oscillator and clock stabilization
- PLL power conditioning
Procurement Notes
Verify the specific suffix -R7 indicates tape and reel packaging configuration. Confirm the ACPZ designation corresponds to the 8-lead LFCSP package type. Ensure the component meets required environmental specifications for the intended operating temperature range.
Selection Notes
Select this variant when a fixed 1.8 V rail is required without external feedback resistors. Consider the LFCSP package for applications demanding high thermal efficiency in small footprints. Verify that the input voltage remains within the specified 3.3 V to 20 V operational window.
Part Context
This component belongs to the ADP7104 family of high input voltage LDO regulators. The series supports multiple fixed output options and adjustable configurations. It is designed for battery-operated equipment due to low quiescent current consumption at full load conditions.
Replacement Considerations
Check datasheet compatibility for pin-out and electrical parameters before substituting. Verify package dimensions match existing PCB layout constraints.
