Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL78302ARFBZ

ISL78302ARFBZ

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

The ISL78302ARFBZ is a dual-channel, low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It features two independent positive fixed output channels with a maximum output current of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and supports fixed output voltages including 1.2V and 2.5V. It is housed in a 10-lead DFN package and is qualified for automotive applications under the AEC-Q100 standard.

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

Dual-channel architecture providing independent power regulation for multiple system components
Automotive-grade qualification ensuring reliability in demanding vehicle environments
High Power Supply Rejection Ratio (PSRR) to minimize noise from input sources

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

Automotive infotainment systems requiring stable power rails
Sensor modules in automotive electronic control units (ECUs)

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

Verify the specific output voltage configuration (e.g., 1.2V/2.5V) against the datasheet, as suffixes may denote different fixed voltage combinations. Confirm the package type matches the PCB footprint requirements. Ensure the component meets the required AEC-Q100 grade for the target automotive application environment.

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

Select this component when dual isolated LDO outputs are needed in a compact automotive form factor. Consider the 300mA current limit per channel and the 6.5V maximum input voltage. Evaluate the dropout voltage characteristics at the expected load current to ensure sufficient headroom from the input supply rail.

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

This part belongs to the ISL78302A series of high-performance, low-noise LDO regulators designed specifically for automotive electronics. The series emphasizes high PSRR and low quiescent current to support sensitive analog and digital loads in vehicles while maintaining efficiency and thermal performance.

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

Check for direct pin-compatible alternatives within the ISL78302 family that offer different fixed voltage combinations. Verify if newer generation Renesas automotive LDOs provide equivalent electrical specifications and packaging options.
