ISL78302AARJCZ

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

The ISL78302AARJCZ is a dual-channel low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages, specifically 2.6 V and 2.8 V. Each channel supports an output current of 300 mA with a typical dropout voltage of 250 mV. The device features high power supply rejection ratio (PSRR) of 90 dB and maintains a low quiescent current of 47 µA. Designed for automotive applications, it is qualified under AEC-Q100 standards and housed in a compact 10-DFN package.

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

Verify the specific suffix 'JCZ' against official Renesas documentation to confirm exact output voltage combinations and packaging details. Confirm end-of-life status as indicated by recent PCN data. Ensure RoHS compliance and moisture sensitivity level requirements are met for your assembly process. Cross-reference the datasheet revision to validate pinout and electrical characteristics before finalizing procurement.

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

Select this component when dual isolated rails are required from a single input source in automotive environments. The fixed output options eliminate external resistor networks. Consider the 47 µA quiescent current for battery efficiency. Verify that the 300 mA per channel meets peak load demands. The 10-DFN package suits space-constrained PCB layouts.

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

This part belongs to the ISL78302A series of low-dropout regulators designed for automotive applications. The series emphasizes low noise and high PSRR, making it suitable for sensitive analog loads. Renesas acquired Intersil, which originally developed this line, ensuring continued support through Renesas Electronics Corporation. The family targets body electronics and sensor interfaces requiring stable, clean power.

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

Check for direct pin-to-pin replacements within the ISL78302A family with different output voltage suffixes. Verify if newer Renesas LDOs offer improved PSRR or lower quiescent current while maintaining the same package footprint. Consult official substitution guides for any updated components replacing the legacy Intersil design.
