ISL9014AIRCJZ

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

The ISL9014AIRCJZ is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It provides two independent fixed positive output voltages of 1.8V and 2.8V, each capable of sourcing up to 300mA of current. The device operates with an input voltage range from 2.3V to 6.5V. Key electrical parameters include a maximum dropout voltage of 0.2V at 150mA and 0.5V at 300mA for the respective outputs. The quiescent current is typically 40µA when both LDOs are active. It features high power supply rejection ratio (PSRR) of 70dB at 1kHz and includes protection mechanisms such as overcurrent, thermal shutdown, and soft start.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to soldering. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure proper handling procedures are followed during storage and assembly to prevent damage to the DFN package.

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

Select this component when dual isolated low-noise outputs are required within a compact footprint. Consider the 300mA per channel limit for load requirements. Evaluate the 2.3V minimum input voltage constraint against system battery discharge curves. Compare dropout characteristics against specific load currents to ensure regulation stability. Verify compatibility with external capacitor ESR specifications for stability.
