ISL9011AIRFDZ

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

The ISL9011AIRFDZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages: 2.5 V and 5.0 V. The device features a maximum output current capability of 150 mA per channel, with a typical dropout voltage of 250 mV at full load. It incorporates annealed wafer processing for low noise performance and high power supply rejection ratio (PSRR). The component is housed in a compact 10-lead DFN package measuring 3 mm x 3 mm.

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

Verify the specific suffix FDZ against official Renesas documentation to confirm the exact output voltage combination and package variant. Confirm RoHS compliance status and lead-free plating specifications prior to integration. Check for end-of-life notices or obsolescence warnings as this series may have limited availability through authorized channels.

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

Select this component when dual isolated LDOs are required in a minimal footprint application. Ensure the input voltage remains above the sum of the highest output voltage and the dropout voltage under maximum load conditions. Verify that the thermal dissipation capabilities of the 3x3 DFN package are sufficient for the expected ambient temperature and load current profile.

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

This part belongs to the ISL9011A family of dual LDO regulators known for their low quiescent current and high PSRR.
