ISL9000IRJNZ

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

The ISL9000IRJNZ is a dual-channel linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output voltages of 2.8V and 3.3V, each capable of delivering up to 300mA of output current. The device operates with an input voltage range up to a maximum of 6.5V. Key electrical specifications include a maximum static current of 32µA and a maximum supply current of 52µA. The typical dropout voltage is specified at 0.4V for the first channel and 0.325V for the second channel when loaded at 300mA. The component is housed in a 10-lead VFDFN package with dimensions of 3.00mm x 3.00mm and a height of 0.88mm.

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

• Integrates two independent LDO regulators within a single compact package to reduce board space.
• Includes integrated Power-On Reset (POR) circuitry and enable control functionality.
• Provides comprehensive protection against overcurrent conditions, thermal overload, and under-voltage lockout.

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

• Portable electronic devices requiring multiple stable voltage rails from a single source
• Battery-powered systems prioritizing low quiescent current consumption
• Embedded circuits needing simultaneous power-on reset sequencing

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

Verify the specific output voltage combination required, as the suffix indicates a 2.8V/3.3V configuration. Confirm package integrity upon receipt, as the VFDFN format requires precise soldering techniques. Check manufacturer documentation for any product change notices or end-of-life announcements prior to final design approval.

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

Select this component when a dual-output solution is necessary to minimize footprint. Ensure the input voltage does not exceed the 6.5V absolute maximum rating. Consider the thermal performance requirements given the 300mA per channel capability and the small surface-mount package size.

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

This part belongs to the ISL9000 series of dual LDO regulators. It shares the same physical package and core protection features with variants offering different fixed output voltage combinations. The series is designed for applications requiring efficient power management in space-constrained environments.

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

Consult official substitution lists for compatible parts within the ISL9000 family that match the required output voltages. Verify pin compatibility and thermal characteristics before replacing with other dual LDO packages.
