ISL9016IRUMWZ-T

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

The ISL9016IRUMWZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two positive, fixed output voltages of 2.85V each with a maximum output current of 150mA per channel. The device operates within an input voltage range of 1.8V to 6.5V and features a typical dropout voltage of 250mV at full load. Key electrical specifications include a quiescent current of 67µA and power supply rejection ratios (PSRR) of 80dB at 1kHz and 45dB at 1MHz. It is housed in a compact 6-UTDFN (1.6x1.6mm) package with an exposed pad.

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

Verify component authenticity through authorized distributors as the part status is End-of-Life. Confirm package marking and date codes against official Renesas production change notices. Ensure compatibility with existing PCB footprints for the 6-UTDFN form factor. Review RoHS3 compliance documentation for environmental regulations. Validate that replacement strategies account for long-term availability constraints.

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

Select this component when dual fixed 2.85V outputs are required in a minimal footprint application. Consider the 150mA current limit per channel against total system load requirements. Evaluate the 67µA quiescent current impact on overall battery life compared to higher-performance alternatives. Assess the 6.5V maximum input voltage against the highest expected supply rail. Verify thermal dissipation capabilities within the 6-UTDFN package for the specific ambient temperature conditions.
