ISL9011AIRMNZ

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

The ISL9011AIRMNZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed positive output voltages, typically 2.8 V and 3.3 V. The device supports maximum output currents of 150 mA per channel. Key electrical specifications include a typical dropout voltage of 250 mV at 300 mA, a noise level of 30 μVRMS from 10 Hz to 100 kHz, and a power supply rejection ratio (PSRR) of up to 70 dB at 1 kHz. Voltage regulation accuracy is maintained at ±1.8%. The component functions reliably across an operating temperature range of -40°C to +85°C.

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

Verify the specific suffix code against official Renesas documentation to confirm exact output voltage combinations and package variations. Confirm current availability status as certain variants may be subject to limited supply or end-of-life notices. Ensure compatibility with existing PCB footprints and thermal design constraints before finalizing procurement decisions.

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

Select this component when simultaneous dual rails are required with strict noise limitations. Evaluate the input-to-output voltage differential to ensure dropout characteristics meet load transient requirements. Consider the 10-DFN package dimensions for space-constrained designs. Verify that the fixed output options align precisely with target logic levels without requiring external adjustment resistors.
