ISL78302ARCWZ-T

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

The ISL78302ARCWZ-T is a dual-channel low-dropout (LDO) voltage regulator from the Renesas ISL78302A series, designed for automotive applications. It features two positive fixed output channels with a maximum output current of 300 mA per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages of 1.2 V and 2.5 V. It exhibits a typical power supply rejection ratio (PSRR) of 64 dB and a quiescent current of 47 µA. The regulator includes protection features such as overcurrent and thermal shutdown, ensuring reliable performance in harsh environments.

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

• Dual-channel architecture providing independent 1.2 V and 2.5 V outputs for simultaneous power rail generation.
• High power supply rejection ratio (PSRR) ensures effective noise suppression for sensitive analog circuits.
• Automotive-grade qualification supports operation across extended temperature ranges required for vehicle electronics.

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

• Powering sensor interfaces in automotive infotainment systems
• Supplying stable voltage rails for microcontroller units (MCUs)
• Providing clean power to analog-to-digital converters (ADCs) in data acquisition modules

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

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the fixed output combination matches the design requirement of 1.2 V and 2.5 V. Ensure compatibility with the 10-DFN package footprint and verify AEC-Q100 compliance 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 required in a compact form factor. The low quiescent current makes it suitable for battery-powered automotive subsystems. Compare against single-channel alternatives if only one rail is needed, or consider higher current variants if load requirements exceed 300 mA per channel.

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

The ISL78302A series belongs to Renesas' portfolio of high-performance, low-noise LDO regulators tailored for automotive use. These devices are part of a broader family including single-channel variants and different output configurations, all sharing common protection features and automotive reliability standards.

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

Check for direct pin-compatible substitutes within the ISL78302A family with matching output voltages. Verify equivalent PSRR and dropout characteristics against alternative automotive LDOs from other manufacturers if supply constraints exist.
