ADM8828ART-REEL

Overview

The ADM8828ART-REEL is a switching voltage regulator manufactured by Analog Devices Inc., classified as a charge pump inverter with shutdown capability. It operates within an input voltage range of 1.5 V to 5.5 V and provides a negative output voltage ranging from -1.5 V to -5.5 V. The device delivers an output current of 25 mA through a single output channel. Key electrical parameters include a static current of 600 uA, a working power supply current of 1 mA, and a switching frequency of 120 kHz. It is housed in a SOT-23-6 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump topology for generating inverted voltage outputs from positive supply rails
• Dedicated shutdown pin allows for active control of power consumption and system state management
• Compact SOT-23-6 surface-mount packaging designed for space-constrained circuit board layouts

Applications

• Portable electronic devices requiring negative bias voltages for analog circuits
• Battery-powered systems utilizing low-voltage inputs to generate required signal levels
• Communication equipment needing isolated negative supply rails for interface components

Procurement Notes

Verify the specific suffix 'ART' against official Analog Devices documentation to confirm tape-and-reel packaging configuration and temperature grade. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Cross-reference the part number with current manufacturer lifecycle status to confirm availability and obsolescence risks before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is needed to invert low input voltages (1.5V–5.5V) into negative outputs up to -5.5V. The 25 mA output current capacity suits moderate load requirements. Consider the 120 kHz switching frequency for EMI constraints and the shutdown feature for power-sensitive applications. Validate that the SOT-23-6 package fits the mechanical design constraints.

Part Context

This part belongs to the ADM8828 series of charge pump inverters from Analog Devices. It is categorized under Switching Voltage Regulators within the PMIC (Power Management ICs) subcategory. The device is distinct from linear regulators or buck converters, specifically designed for inverting topologies in portable electronics where efficiency and size are critical factors.

Replacement Considerations

Consult Analog Devices datasheets for direct pin-compatible alternatives within the ADM8828 family. Verify if other suffixes (e.g., ARZ) offer identical functionality with different packaging or environmental certifications. Do not assume cross-compatibility with unrelated charge pump models without verifying electrical specifications and pinout definitions.
