ISL9001IRJZ-T

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

The ISL9001IRJZ-T is a single-output low dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.8V with a maximum output current of 300mA. The device operates with an input voltage range up to 6.5V and features a typical quiescent current of 32 µA. It offers high power supply rejection ratio (PSRR) performance, specified at 90dB at 1kHz. The component is housed in an 8-DFN (2x3mm) package with exposed pad for thermal dissipation.

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

Verify the obsolete status of this specific part number before procurement planning. Confirm that the 8-DFN package dimensions match your PCB footprint requirements. Ensure compatibility with RoHS compliance standards if required by your manufacturing process. Check for available replacement components from the manufacturer's portfolio due to potential end-of-life constraints.

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

Select this component when a fixed 2.8V output is required with minimal external components. Consider the 300mA current limit for load requirements. Evaluate the 6.5V maximum input voltage against your system's supply rail. The small 2x3mm DFN package is suitable for space-constrained designs. Verify thermal performance under expected load conditions given the package size.
