ISL9014AIRNJZ-T

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

The ISL9014AIRNJZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output regulators within a single package, designed for applications requiring efficient power management with minimal noise. The device supports an input voltage range from 2.3V to 6.5V and provides a maximum output current of 300mA per channel. Key electrical specifications include a typical quiescent current of 40µA and high power supply rejection ratio (PSRR). It features comprehensive protection mechanisms including overcurrent, thermal shutdown, and soft-start functionality.

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

Verify the specific suffix 'NJZ' against official Renesas documentation to confirm pinout compatibility and tape-and-reel packaging details. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notices as older Intersil/Renesas components may have limited availability or obsolescence risks.

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

Select this component when a compact dual-output solution is required for space-constrained designs. Ensure the load current does not exceed 300mA per channel. Verify that the required output voltages match the available fixed options in the datasheet. Consider the thermal dissipation capabilities of the DFN-10 package under maximum load conditions.
