ISL9000IRNJZ-T

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

The ISL9000IRNJZ-T is a dual-output low dropout (LDO) voltage regulator from the ISL9000A series, manufactured by Renesas Electronics. It features two fixed output channels providing 2.8 V and 3.3 V, each capable of delivering up to 300 mA. The device operates with an input voltage range of 2.3 V to 6.5 V and utilizes a 10-DFN (3x3 mm) surface-mount package with an exposed pad. Key electrical characteristics include a maximum dropout voltage of 0.4 V at 300 mA for one channel and 0.325 V at 300 mA for the other. It incorporates internal protections such as overcurrent, thermal shutdown, and under-voltage lockout.

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

• Dual-channel architecture providing independent 2.8 V and 3.3 V fixed outputs within a single compact package.
• Integrated protection mechanisms including overcurrent limiting, thermal shutdown, and under-voltage lockout for system reliability.
• Low quiescent current operation with enable control and power-on reset functionality to optimize power management.

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

• Portable electronic devices requiring efficient dual-rail power distribution
• Embedded systems utilizing microcontrollers or digital signal processors
• Battery-powered equipment needing stable voltage regulation

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

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level before integration. Review product change notices for any packaging or labeling updates issued by the manufacturer. Ensure supply chain stability as availability may be limited.

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

Select this component when dual fixed outputs of 2.8 V and 3.3 V are required in a space-constrained design. Consider the 300 mA per channel limit and input voltage range of 2.3 V to 6.5 V. The 10-DFN package suits surface-mount assembly processes. Evaluate thermal performance given the small footprint and potential heat dissipation requirements.

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

This part belongs to the ISL9000A series of low-noise, high-PSRR LDO regulators designed for portable applications. It represents a transition from Intersil to Renesas Electronics following corporate acquisitions. The series emphasizes low static current and high power supply rejection ratio to support sensitive analog and digital circuits in mobile and handheld devices.

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

Check for direct pin-compatible alternatives within the ISL9000 family or newer Renesas LDO portfolios. Verify that substitute components match the 2.8 V/3.3 V output configuration and 300 mA current rating. Assess package compatibility with existing PCB layouts.
