ISL9011IRGCZ

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

The ISL9011IRGCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas. It features two independent channels with fixed output voltages of 2.7V and 1.8V. The device supports a maximum input voltage of 6.5V and operates within an ambient temperature range of -40°C to +85°C. Channel 1 provides a continuous output current of 150mA, while Channel 2 delivers up to 300mA. The component is housed in a compact 10-lead DFN (3x3mm) package.

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

• Dual-channel architecture providing independent regulated outputs for separate power domains
• High Power Supply Rejection Ratio (PSRR) suitable for noise-sensitive analog circuits
• Low quiescent current consumption to minimize standby power loss
• Stable operation with ceramic capacitors having low equivalent series resistance

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

• Portable electronic devices requiring multiple stable voltage rails

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

Verify the manufacturer origin, as Intersil operations are integrated into Renesas Electronics. Confirm the specific suffix 'GCZ' corresponds to the 2.7V/1.8V fixed output configuration and the 10-DFN package type. Ensure compliance with RoHS directives and check for any end-of-life notices or limited availability status from authorized distributors before finalizing procurement plans.

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

Select this component when a dual LDO solution is required to save board space compared to using two single regulators. It is appropriate for designs where input voltages do not exceed 6.5V and where low noise performance is critical for downstream analog components. Consider the thermal dissipation capabilities of the DFN package relative to the expected load currents and ambient operating conditions.
