ADP667ARZ-REEL7

Overview

The ADP667ARZ-REEL7 is a low-dropout precision voltage regulator manufactured by Analog Devices Inc. It provides a fixed +5 V output or an adjustable range from +1.3 V to +16 V using external resistors. The device delivers up to 250 mA of output current with a dropout voltage of 150 mV at 200 mA. It operates within an input voltage range of 3.5 V to 16.5 V and features a quiescent current of 20 mA, reducing to 0.2 mA in shutdown mode. The component is housed in an 8-lead SOIC package and functions reliably across the industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Supports fixed +5 V configuration without external components or adjustable output via external resistors
• Includes integrated dropout detector and low battery monitoring comparator for system status indication
• Features digital shutdown control to minimize power consumption during standby periods

Applications

• Handheld instruments
• Cellular telephones
• Battery operated devices
• Portable equipment
• Solar powered instruments

Procurement Notes

Verify that the specific REEL7 suffix corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package variant matches the PCB footprint design specifications exactly to prevent mounting errors.

Selection Notes

Select this regulator when designing systems requiring high efficiency under limited headroom conditions. The low dropout characteristic extends battery life in portable applications. Verify that the thermal dissipation requirements are met within the operating ambient temperature range. Consider the integrated monitoring features if supply stability tracking is necessary for the target application.
