Overview
The ADP7102ACPZ-1.8-R7 is a fixed-output CMOS low dropout linear regulator manufactured by Analog Devices Inc. It provides a regulated 1.8 V output with a maximum current capability of 300 mA, operating from an input voltage range of 3.3 V to 20 V. The device features low noise performance and high power supply rejection ratio (PSRR). It incorporates reverse current protection, foldback current limit, and thermal overload protection. The component is housed in an 8-lead LFCSP package.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes programmable undervoltage lockout and power-good indicator
- Features reverse current protection and thermal shutdown
Applications
- Regulation for ADC and DAC circuits
- Precision amplifier power supplies
- High frequency oscillators and clocks
- Phase-locked loops
- Medical and healthcare equipment
Procurement Notes
Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the ACPZ designation matches the LFCSP package type needed for your PCB footprint. Ensure the 1.8 V fixed output variant aligns with your system voltage requirements before finalizing procurement.
Selection Notes
Select this component when a stable 1.8 V rail is required from higher input voltages up to 20 V. It is appropriate for designs needing low quiescent current and minimal output noise without requiring large external capacitors. Consider the LFCSP package for compact layouts requiring good thermal dissipation.
Part Context
This part belongs to the ADP7102 family of high input voltage, low noise CMOS LDO regulators. The family offers multiple fixed output voltage options and an adjustable version. The ACPZ suffix indicates the 8-lead LFCSP package, while the -1.8 specifies the fixed 1.8 V output voltage setting within the series.
Replacement Considerations
Other variants within the ADP7102 family offer different fixed output voltages or adjustable configurations. Verify pin compatibility if substituting with other packages like SOIC. Check datasheets for any differences in thermal resistance or electrical specifications between package types.
