ISL78302AARJMZ-T7A

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

The ISL78302AARJMZ-T7A is an automotive-grade dual low-dropout (LDO) voltage regulator from the Renesas ISL78302A series. It integrates two independent LDO channels, each capable of sourcing up to 300mA. The device features a wide input voltage range of 2.3V to 6.5V and delivers fixed output voltages of 2.8V and 3.0V. Key electrical specifications include a typical quiescent current of 47µA with both outputs active, a shutdown current below 0.3µA, and a high power supply rejection ratio (PSRR) of 90dB at 1kHz. The unit operates within a temperature range of -40°C to +105°C and utilizes a 10-lead DFN package.

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

Verify the specific suffix T7A against official Renesas documentation to confirm reel quantity and tape specifications. Confirm AEC-Q100 qualification status and RoHS compliance details directly with the manufacturer or authorized distributors. Check for end-of-life notices or production change notifications that may affect long-term availability.

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

Select this component when dual isolated low-noise supplies are required for automotive electronics. Ensure the load current does not exceed 300mA per channel. Verify that the input voltage remains within the 2.3V to 6.5V window. Consider the thermal dissipation capabilities of the 10-DFN package under maximum load conditions.
