ISL9012IRNNZ

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

The ISL9012IRNNZ 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, typically 3.3 V for each channel. The device supports maximum output currents of 150 mA and 300 mA per regulator. Key electrical specifications include a typical dropout voltage of 200 mV at 150 mA and a noise level of 30 μVRMS from 10 Hz to 100 kHz. It features high power supply rejection ratio (PSRR) and includes enable/shutdown control. The component is housed in a 10-lead DFN package measuring 3.0 mm x 3.0 mm with a 0.5 mm pitch.

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 distribution channels may list obsolete or limited-stock items. Ensure compatibility with RoHS and lead-free manufacturing standards required for your assembly process. Cross-reference the datasheet revision date to validate technical parameters before finalizing procurement orders.

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

Select this component when dual isolated LDOs are required in a space-constrained design. Evaluate the total quiescent current consumption against battery life requirements. Consider the thermal dissipation capabilities of the DFN package under maximum load conditions. Verify that the input voltage range aligns with the system's available power source without exceeding the 6.5 V maximum rating.
