ISL78302AR1AZ

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

The ISL78302AR1AZ is a dual low-dropout (LDO) voltage regulator from the Renesas ISL78302 series, designed for automotive applications. It features two independent positive fixed outputs housed in a compact 10-DFN (3x3 mm) package. Each output provides a maximum current of 300 mA with a typical dropout voltage of 230 mV at full load. The device operates within an input voltage range of 2.3 V to 6.5 V and maintains a wide operating temperature range from -40°C to +105°C. It includes integrated protection features such as overcurrent limiting and thermal shutdown.

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

Verify the specific suffix AR1AZ against the official Renesas datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure packaging type matches design requirements for surface mount processing.

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

Select this component when dual isolated LDOs are required in space-constrained automotive designs. The 300 mA per channel rating suits moderate load applications. Verify that the fixed output voltages meet circuit requirements, as adjustable variants exist within the same family. Consider the 10-DFN footprint compatibility during PCB layout phase.

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

Part of the ISL78302 family of high-performance dual LDOs. Shares core topology with variants like ISL78302AARJRZ but differs in package and specific output configurations. Designed to replace older Intersil dual LDO solutions in modern automotive platforms requiring high PSRR and low noise.

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

Direct substitutes include ISL78302AARJRZ and ISL78302ARNWZ. Verify output voltage options and package dimensions before substitution. Cross-reference thermal performance and pin assignments to ensure board-level compatibility.
