ISL9011IRJCZ

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

The ISL9011IRJCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas/Intersil. It features two independent output channels with fixed voltages of 1.8V and 2.8V. The device supports a maximum input voltage of 6.5V and operates within a temperature range of -40°C to +85°C. Channel 1 provides an output current of 150mA, while Channel 2 delivers 300mA. It utilizes a DFN-10 package.

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

• Dual-channel architecture providing independent 150mA and 300mA outputs for flexible power distribution.
• High power supply rejection ratio (PSRR) optimized for noise-sensitive RF and imaging applications.
• Low quiescent current consumption enhances battery life in portable electronic devices.
• Integrated reference bypass pin allows external capacitor connection for further noise filtering.

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

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding manufacturing site updates. Ensure the specific suffix matches required packaging and thermal specifications before integration into design.

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

Select this component when dual isolated rails are required with asymmetric current capabilities. It is suitable for designs needing high PSRR at 1kHz. Compare against ISL9011AIRJCZ for annealed variants or ISL9011IRKJZ for different output voltage combinations. Ensure output capacitance remains between 1µF and 10µF for stability.

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

Part of the Intersil ISL9000 series of high-performance dual LDOs. This series targets applications requiring ultra-low noise and high PSRR. The ISL9011 variant specifically distinguishes itself with a 150mA/300mA current split, differing from the ISL9000's symmetric output configuration.

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

ISL9011AIRJCZ: Annealed version with potentially tighter noise specifications. ISL9011IRKJZ: Dual channel with different fixed output voltages (e.g., 2.8V/2.85V). Verify pin compatibility and thermal performance when substituting.
