ISL9011IRJBZ-T

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

The ISL9011IRJBZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation, housed in a 10-lead 3mm x 3mm Dual Flat No-Lead (DFN) package. It provides two fixed positive output voltages: Channel 1 outputs 2.8V at up to 150mA, and Channel 2 outputs 1.5V 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 LDOs are active. It includes separate enable pins for each channel, soft-start functionality, and protection against overcurrent and thermal overload.

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

• Integrates two high-performance LDOs with independent enable controls and soft-start capabilities to limit input current surges during activation.
• Delivers excellent load regulation and transient response while maintaining stability with ceramic output capacitors ranging from 1µF to 10µF.
• 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 Applications

• PDAs, Cell Phones and Smart Phones
• Portable Instruments and MP3 Players
• Handheld Devices including Medical Handhelds

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

Verify the specific suffix '-T' indicates tape and reel packaging rather than tube. Confirm the exact output voltage combination matches the 'JB' designation (2.8V/1.5V). Check for RoHS compliance status and ensure the operating temperature range meets system requirements. Validate pin compatibility if replacing older Intersil versions.

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

Select this component when a compact dual-output solution is required for portable electronics. Ensure the application benefits from the low quiescent current and high PSRR characteristics. Verify that the required output voltages match the factory-trimmed options available in the ISL9011 series. Consider the thermal performance within the DFN package for the expected load conditions.
