ISL9014AIRGPZ-T

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

The ISL9014AIRGPZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages: VO1 at 2.7V and VO2 at 1.85V. Each LDO channel supports a continuous maximum output current of 300mA. The device operates with an input voltage range from 2.3V to 6.5V and maintains a typical quiescent current of 45µA when both regulators are active. It features a shutdown mode drawing less than 0.1µA, ±1.8% regulation accuracy, and soft-start functionality. The component is housed in a 10-lead 3mm x 3mm DFN package.

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

Verify the specific ordering suffix 'GPZ' to confirm the exact output voltage combination of 2.7V on VO1 and 1.85V on VO2. Confirm that the package type matches the required 10-lead 3x3mm DFN footprint. Ensure compatibility with RoHS compliance standards as indicated by the manufacturer's Pb-free designation. Check for any recent product change notices regarding manufacturing updates or end-of-life status.

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

Select this component when a compact dual-output power solution is required for battery-operated portable electronics. The low dropout voltage and high PSRR make it suitable for noise-sensitive analog circuits. Verify that the application load does not exceed the 300mA per channel limit. Consider the thermal performance within the 3x3mm DFN package if operating near maximum current levels.
