ISL9011IRGPZ

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

The ISL9011IRGPZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation, housed in a 10-lead 3mm x 3mm DFN package. It provides two fixed output voltages: Channel 1 outputs 2.7V at up to 150mA, and Channel 2 outputs 1.85V at up to 300mA. The device operates with an input voltage range of 2.3V to 6.5V and features a typical quiescent current of 45µA when both channels are active. It includes separate enable pins for each LDO, achieving less than 0.1µA shutdown current.

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

• Integrates two high-performance LDOs with independent enable controls and soft-start functionality to limit input current surges during activation.
• Delivers excellent transient response and load regulation across the full operating temperature range while maintaining stability with ceramic capacitors.
• Features a reference bypass pin that allows external capacitor adjustment to optimize noise filtering and power supply rejection ratio performance.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status as specified in datasheet documentation. Check for specific ordering suffixes if tape and reel packaging is required instead of standard tube packaging. Ensure compatibility with existing PCB land patterns for the 10-DFN package.

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

Select this component when dual isolated rails are needed from a single input source within the 2.3V to 6.5V range. Consider the specific fixed output voltages of 2.7V and 1.85V for precise system requirements. Evaluate thermal management needs based on the 10-DFN package dimensions and ambient operating conditions up to 85°C.
