ISL78302AARPLZ-T7A

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

The ISL78302AARPLZ-T7A is an automotive-grade dual low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It integrates two independent LDO channels, each capable of sourcing up to 300mA. The device operates with a wide input voltage range from 2.3V to 6.5V and delivers fixed output voltages of 1.85V and 2.9V. Key electrical characteristics include a typical quiescent current of 47µA, a power supply rejection ratio (PSRR) of 90dB at 1kHz, and a maximum dropout voltage of 230mV. It features individual enable pins, power-on-reset functions, and protection against overcurrent and thermal overload.

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

Select this component when designing automotive circuits requiring dual isolated low-noise supplies from a single input rail. Ensure the required output voltages match the fixed options available in the package variant. Verify that the load current requirements do not exceed 300mA per channel and that the input voltage remains within the 2.3V to 6.5V operational window.

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

This device belongs to the ISL78302A series of dual LDO regulators designed for automotive applications. It is part of Renesas' portfolio of power management integrated circuits aimed at providing efficient and reliable voltage regulation for complex electronic systems in vehicles. The series is characterized by its low standby current and high rejection ratios.

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 combinations. Consult Renesas for updated lifecycle information regarding the EOL date. Evaluate alternative dual LDOs from other manufacturers if long-term supply continuity is critical for the design.
