ISL80101IRAJZ

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

The ISL80101IRAJZ is a single-output, low-dropout linear regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.2V to 6V and provides an adjustable output voltage from 0.8V to 5V with a maximum continuous output current of 1A. The device features a typical dropout voltage of 130mV at full load and offers high power supply rejection ratio performance. It includes programmable current limiting, soft-start functionality, and power-good signaling. The component is housed in a compact 10-lead DFN package measuring 3mm x 3mm.

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

Verify the specific suffix 'RAJZ' against the manufacturer's official datasheet to confirm the exact output voltage configuration and packaging type. Ensure compatibility with RoHS directives and moisture sensitivity levels required for your assembly process. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

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

Select this component when a 1A output current is sufficient for the application load. The adjustable output feature makes it suitable for designs requiring non-standard voltage rails. Consider the thermal performance of the 10-DFN package relative to the expected ambient temperature and PCB copper area. Verify that the input voltage remains above the minimum requirement while accounting for the dropout voltage at maximum load.
