ISL9011AIRCJZ

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

The ISL9011AIRCJZ is a dual low-dropout linear regulator from the Renesas ISL9011A series, housed in a 10-lead DFN (3x3 mm) package. It provides two fixed positive output voltages of 1.8 V and 2.8 V with a maximum output current of 150 mA per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 250 mV at full load. It includes integrated enable/shutdown control, overcurrent protection, thermal shutdown, and soft-start functionality. The unit supports operation from -40°C to +85°C.

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

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm exact suffix specifications match design requirements since variations exist within the family. Check moisture sensitivity level handling procedures if storage duration exceeded limits. Validate that the specific output voltage combination matches the target application needs before integration.

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

Select this component when dual isolated rails are required from a single input source without external resistors. Consider the 150 mA current limit against peak load demands to ensure adequate headroom. Evaluate the 250 mV dropout characteristic against minimum input voltage constraints during battery discharge cycles. Ensure PCB layout accommodates the exposed pad thermal dissipation requirements for reliable operation.
