ISL9012IRGCZ

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

The ISL9012IRGCZ is a dual low-dropout linear regulator (LDO) manufactured by Renesas Electronics Corporation, housed in a 10-lead 3x3mm DFN package. It integrates two independent LDO channels: Channel 1 provides a fixed 2.8V output with a maximum continuous current of 150mA, while Channel 2 delivers a fixed 1.8V output capable of sourcing up to 300mA. The device operates within an input voltage range of 2.3V to 6.5V and maintains a typical quiescent current of 45µA when both outputs are active. It features high power supply rejection ratio (PSRR) of 70dB at 1kHz, low output noise, and includes integrated protection mechanisms such as thermal shutdown, current limiting, and soft-start functionality.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot traceability requirements. Ensure proper electrostatic discharge handling procedures are followed during storage and assembly to prevent damage to the sensitive internal circuitry.

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

Select this component when a compact dual-output solution is required for battery-powered applications. The fixed 2.8V and 1.8V outputs suit systems needing distinct logic and analog rails. Verify that the total load current does not exceed the 150mA and 300mA limits for each respective channel. Ensure adequate thermal management on the PCB ground plane due to the small package footprint.
