ISL78302ARCWZ-T7A

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

The ISL78302ARCWZ-T7A is an automotive-grade dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It features two independent output channels with fixed voltages of 1.2V and 2.5V, each capable of delivering up to 300mA. The device operates within a maximum input voltage of 6.5V and maintains a typical dropout voltage of 0.3V at full load. Designed for high performance in noisy environments, it offers ultra-low noise and high power supply rejection ratio (PSRR). The IC includes integrated protection mechanisms such as overcurrent limiting and thermal shutdown, ensuring reliable operation across the specified temperature range.

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

Verify the complete part number including the suffix -T7A to ensure correct tape-and-reel packaging configuration. Confirm that the required output voltages match the fixed 1.2V and 2.5V specifications, as adjustable variants are not available in this specific package. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with the 10-DFN 3x3mm footprint during PCB layout design.

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

Select this component when dual isolated LDOs are required in a compact automotive environment. The fixed output configuration eliminates the need for external feedback resistors, simplifying the bill of materials. Consider the 300mA current limit per channel against total system load requirements. The 6.5V maximum input voltage defines the upper bound for battery-fed or alternator-regulated systems without pre-regulation.
