ISL78302ARNBZ-T

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

The ISL78302ARNBZ-T 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 of output current. The device operates within a wide input voltage range of 2.3V to 6.5V and features very high power supply rejection ratio (PSRR) and low output noise, making it suitable for sensitive analog circuits. It includes individual enable pins and power-on-reset (POR) functions for each channel. The component is housed in a compact 10-lead DFN package and is rated for operation across the extended automotive temperature range.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the fixed output voltage combination matches the design requirements, as variants exist with different voltage pairs. Ensure the order quantity aligns with the manufacturer's minimum reel size specifications. Check for any recent production change notices regarding pinout or thermal characteristics before finalizing procurement.

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

Select this component when dual isolated rails are required from a single input source. It is appropriate for designs needing high ripple rejection without external filtering capacitors. Consider the quiescent current consumption if battery life is critical. Verify that the load transient response meets the dynamic current demands of the downstream digital logic or analog front-end.

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

This part belongs to the ISL78302A family of high-performance dual LDOs designed by Renesas Electronics.
