ADM8830ARU

Overview

The ADM8830ARU is a charge pump regulator designed for color thin film transistor liquid crystal displays. It generates three output voltages from a single 3 V input supply: +5.1 V ± 2%, +15.3 V, and –10.2 V. The device integrates an efficient low dropout voltage regulator to ensure high power efficiency and low ripple on the 5.1 V output. It features low quiescent current and a shutdown function with current consumption below 1 μA. The component supports fast transient response and includes a power-saving mode during blanking periods.

Feature Summary

• Generates three distinct output voltages from a single low-voltage input source
• Integrates a low dropout voltage regulator for stable 5.1 V output
• Supports external LDO configuration for enhanced performance flexibility
• Features ultra-low shutdown current for extended battery life

Applications

• Color TFT LCD panels in mobile phones
• Handheld instruments requiring multiple supply rails
• Cellular phone display driver circuits

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature range specifications. Ensure compatibility with the specific TFT panel requirements regarding output voltage tolerances and current capabilities. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any recent lifecycle status updates or recommended replacements.

Selection Notes

Select this component when designing power supplies for color TFT LCDs requiring positive and negative gate drive voltages alongside a logic supply. Consider its low quiescent current and shutdown features for battery-operated handheld devices. Evaluate the need for external LDO integration if stricter ripple or load regulation is required beyond the internal LDO capabilities.
