ADM8830ARUZ

Overview

The ADM8830ARUZ is a charge pump regulator designed for color thin film transistor liquid crystal displays. It generates three output voltages: +5.1 V, +15.3 V, and -10.2 V from a single 3 V input supply. The device integrates an efficient low dropout voltage regulator to provide a low ripple 5.1 V output. Only a few external capacitors are required for the charge pumps. The LDO can be shut down if an external LDO is used to regulate the 5 V doubler output.

Feature Summary

• Generates three distinct output voltages from a single low-voltage input source
• Integrates a low dropout voltage regulator for stable power delivery
• Optimized for high power efficiency in mobile applications
• Supports shutdown function to minimize current consumption

Applications

• Color TFT LCD panels
• Mobile phones
• Handheld instruments
• Cellular phones

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and electrical characteristics for the target display driver application before integration.

Selection Notes

Select this component when a compact solution is needed to drive TFT LCD gate drivers from a single 3 V supply. It is suitable for designs requiring integrated charge pump regulation with minimal external passive components. Consider the shutdown feature for power management during blanking periods.
