ISL9000AIRJCZ-T

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

The ISL9000AIRJCZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It provides two fixed output voltages of 1.8V and 2.8V from a single package. The device supports an output current of 300mA per channel with a maximum input voltage of 6.5V and a minimum operating input of 2.3V. It features a typical quiescent current of 32µA and includes integrated power-on-reset functions for each output. The component is housed in a 10-lead DFN (3x3mm) surface-mount package and operates within a temperature range of -40°C to +85°C.

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

Verify the specific suffix 'JCZ' confirms the 1.8V/2.8V output configuration before procurement. Confirm RoHS compliance status as required by project specifications. Check for End-of-Life (EOL) notices or obsolescence warnings from the manufacturer. Ensure the DFN-10 package dimensions match the target PCB layout constraints. Validate that the fixed output voltages align with the downstream component requirements.

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

Select this component when two distinct fixed voltage rails are needed from a single LDO source. The 300mA per channel rating suits moderate load applications. Consider the 10-DFN package size for space-constrained designs. Verify that the input voltage range covers the system's supply variations. Evaluate the need for external timing capacitors if POR delay adjustment is required for the second output.

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

This part belongs to the ISL9000A series of dual LDO regulators designed for high performance and low noise. The series typically offers high PSRR and stability with small output capacitors. The 'AIR' designation indicates automotive-grade reliability standards, while 'JCZ' specifies the pinout and output voltage combination. The device integrates protection features such as over-current and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative dual LDOs offering similar 300mA output and DFN-10 packaging. Ensure any replacement maintains the required 1.8V and 2.8V fixed output levels.
