ISL9000IRNNZ

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

The ISL9000IRNNZ is a dual linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output regulators within a single 10-lead DFN package measuring 3x3 mm. Each output channel provides a maximum continuous current of 300 mA with a fixed output voltage of 3.3 V. The device supports an input voltage range up to 6.5 V and maintains a maximum dropout voltage of 0.325 V at full load per channel. Quiescent current consumption is specified at 32 µA, while maximum supply current reaches 52 µA. The component operates reliably across an extended temperature range from -40°C to +85°C.

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

• Integrates two independent high-performance LDO channels capable of sourcing 300 mA each
• Includes individual Power-On-Reset (POR) functions for each output channel
• Provides comprehensive protection against overcurrent, thermal overload, and undervoltage lockout
• Operates stably with ceramic output capacitors ranging from 1 µF to 10 µF

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

• Motor control CPU boards requiring isolated power rails
• Embedded systems utilizing RA series microcontrollers
• Portable electronic devices requiring efficient dual-rail power management
• Industrial equipment needing reliable linear regulation in compact form factors

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

Verify the specific suffix code to confirm output voltage configurations, as variations exist within the ISL9000 family. Confirm package integrity upon receipt, noting the exposed thermal pad design requires proper PCB soldering techniques. Check manufacturer documentation for any Product Change Notices regarding labeling or material updates. Ensure compliance with RoHS3 standards if required by your assembly specifications.

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

Select this component when dual 3.3 V rails are required from a single input source without adjustable output flexibility. Consider the 300 mA limit per channel against peak load demands to ensure adequate thermal headroom. Evaluate the 6.5 V maximum input rating against system supply variations. The fixed 3.3 V outputs simplify board layout compared to adjustable regulators, reducing external component count.

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

This part belongs to the ISL9000 series of dual LDO regulators designed for space-constrained applications. It succeeds earlier Intersil designs now managed under Renesas Electronics.
