ISL9012IRCJZ

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

The ISL9012IRCJZ is a dual low-dropout linear regulator manufactured by Renesas Electronics. It integrates two independent LDO channels within a compact 10-lead DFN package. Channel 1 provides a fixed 2.8V output with a maximum current of 150mA, while Channel 2 delivers a fixed 2.85V output capable of sourcing up to 300mA. The device operates from an input voltage range of 2.3V to 6.5V and maintains a typical dropout voltage of 120mV at 150mA load. It features extremely low quiescent current of 45µA when both regulators are active, high power supply rejection ratio of 70dB at 1kHz, and low output noise of typically 30µVRMS.

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

Verify the specific suffix 'C' against official Renesas documentation to confirm exact output voltages and tolerance levels, as variations exist within the ISL9012 family. Confirm RoHS compliance status and lead-free finish requirements prior to integration. Check for end-of-life notices or alternative component recommendations from the manufacturer to ensure long-term supply chain stability.

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

Select this component for applications requiring dual isolated rails with distinct current capabilities in a minimal footprint. The 150mA/300mA split suits biasing logic and analog circuits simultaneously. Ensure input voltage remains within the 2.3V to 6.5V window. Verify that the required output capacitance falls between 1µF and 10µF to maintain stability without external compensation components.

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

This part belongs to the ISL9012 series of dual LDO regulators designed for portable electronics. It shares pin compatibility with competitors like the Micrel MIC2212. The series emphasizes low noise and high PSRR, making it suitable for sensitive RF and audio applications. The 10-lead 3x3mm DFN package allows for significant board space savings compared to traditional SOT packages.
