ISL9014IRGCZ-T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9014IRGCZ-T is a dual-output fixed positive Low Dropout (LDO) voltage regulator manufactured by Intersil, now part of Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two independent outputs with a maximum current of 300 mA each. The device features low noise characteristics and high Power Supply Rejection Ratio (PSRR), making it suitable for sensitive analog circuits. It is housed in a compact 10-lead DFN package measuring 3 mm x 3 mm. The component supports an operating temperature range from -40°C to +85°C and includes separate enable pins for individual output control.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates two high-performance LDO regulators capable of sourcing 300 mA per output
• Provides excellent transient response and load regulation across the full load current range
• Features extremely low quiescent current consumption for energy-efficient operation
• Includes reference bypass pin capability to adjust noise filtering for low noise applications

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low standby current
• RF and communication modules requiring low noise power supplies
• Embedded systems utilizing multiple voltage rails

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific output voltage configuration, as the ISL9014 series offers various fixed voltage combinations (e.g., 2.7V/1.8V, 3.0V/3.3V). Confirm the suffix 'GCZ' corresponds to the correct voltage pair and packaging type. Check for end-of-life status or obsolescence notices from Renesas, as older Intersil parts may have limited availability or require alternative sourcing strategies.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a dual-rail LDO solution is required with minimal board space constraints. Ensure the input voltage remains within the 2.3 V to 6.5 V window. Verify that the total load current does not exceed 300 mA per channel. Consider the thermal performance of the DFN package under maximum load conditions. Compare PSRR requirements against other LDOs if high-frequency noise rejection is critical.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ISL9014 family of dual LDO regulators designed for low-noise, low-power applications. It replaces earlier single-output or higher-power variants where space and efficiency were primary concerns. The integration of two regulators into one package reduces component count and simplifies PCB layout for multi-voltage designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct replacements such as ISL9014AIRGCZ-T or other suffixes indicating different voltage outputs or packaging. Verify compatibility with existing PCB footprints, as DFN packages may vary slightly in pin spacing or thermal pad dimensions.
