ISL9016AIRUNCZ-T

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

The ISL9016AIRUNCZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It features two independent fixed output voltages of 1.8 V and 3.3 V, delivering a combined maximum output current of 1 A. The device operates with an input voltage range from 1.8 V to 6.5 V and maintains a typical dropout voltage of 250 mV. It incorporates low noise architecture for high power supply rejection ratio (PSRR) and ultra-low quiescent current. The component is housed in a compact UTDFN-EP-6 package and supports surface-mount installation.

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

Verify the specific suffix 'IRUN' against official Renesas documentation to confirm the exact output voltage configuration and package variant. Confirm RoHS compliance status and lead-free specifications prior to integration. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) as availability may be restricted. Ensure the UTDFN-EP-6 footprint matches the target PCB layout requirements.

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

Select this component when a dual-rail LDO solution is required to minimize board space and simplify power distribution networks. The fixed 1.8 V and 3.3 V outputs are suitable for standard digital logic families. Consider the 1 A total current capability against the peak load demands of the connected subsystems. The low dropout characteristic ensures efficient regulation even when the input voltage approaches the output levels.

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

This part belongs to the ISL9016 series of dual-output LDO regulators designed for low-power applications.
