ADP7105ACPZ-1.8-R7

Overview

The ADP7105ACPZ-1.8-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., providing a fixed 1.8 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 power supply rejection ratio of 60 dB at 10 kHz. The device incorporates reverse current protection, programmable soft start, and foldback current limiting. It utilizes an 8-lead LFCSP package and maintains stability with small ceramic capacitors.

Feature Summary

Provides low noise regulation suitable for sensitive analog circuits
Includes programmable undervoltage lockout and enable functions
Features integrated thermal overload and foldback current-limit protection

Applications

Regulation of ADC and DAC circuits
Precision amplifier power supplies
High frequency oscillator and clock regulation
PLL power management
Medical and healthcare equipment

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the fixed 1.8 V output variant aligns with the design requirements. Ensure compatibility with the specified operating temperature range and verify all electrical parameters against the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when high input voltages up to 20 V are required alongside low noise performance. The fixed 1.8 V output eliminates external feedback resistors, simplifying the design. Consider the 8-lead LFCSP package for compact layouts requiring excellent thermal dissipation in space-constrained applications.

Part Context

This part belongs to the ADP7105 family of high input voltage LDO regulators. The ACPZ suffix indicates the 8-lead Lead Frame Chip Scale Package (LFCSP) construction. The -R7 designation specifies the reel packaging format used for automated surface-mount assembly processes.
