ISL9011IRJMZ

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

The ISL9011IRJMZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil. It features two independent output channels capable of sourcing 150 mA and 300 mA respectively. The device operates with an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages, such as 2.8 V and 3.0 V. It exhibits a typical quiescent current of 45 µA and maintains stability with output capacitance between 1 µF and 10 µF. The component is housed in a compact 10-lead DFN (3x3 mm) package.

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

Verify the specific output voltage combination required, as the ISL9011 series offers various fixed voltage options. Confirm the package suffix matches the desired thermal and mechanical specifications. Check current availability status, as some variants may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprint designs for the 10-DFN package.

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

Select this component when simultaneous dual-output regulation is necessary with distinct current capabilities. The high PSRR makes it suitable for noise-sensitive applications like RF front-ends or precision sensors. Consider the 1 µF to 10 µF output capacitor requirement for stability. Evaluate the 45 µA quiescent current against system power budget requirements for battery-operated devices.
