ISL80410IBEZ

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

The ISL80410IBEZ is a high-voltage, adjustable output linear regulator (LDO) designed for always-on and keep-alive applications. It supports an input voltage range of +6V to +40V and delivers up to 150mA of output current. The device features a low quiescent current of 18µA typical and a shutdown current of 2µA typical. It offers a precision reference with ±1% accuracy over temperature and load, a low dropout voltage of 295mV at full load, and 26µV RMS noise. The part includes thermal shutdown and current limit protection, operates from -40°C to +125°C, and is housed in an 8-lead EPSOIC package.

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

Verify the specific suffix 'IBEZ' against the manufacturer's latest datasheet to confirm pinout and packaging details. Check for active status or end-of-life notices as component availability may vary. Ensure the selected variant matches the required tape-and-reel or tube packaging format for your assembly process. Confirm RoHS compliance and lead-free status if mandated by your design specifications.

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

Select this component when a wide input voltage range up to 40V is required alongside low static current consumption. It is suitable for applications needing precise voltage regulation without the complexity of switching regulators. Consider the 8-lead EPSOIC package for thermal performance and space constraints. Verify that the 150mA output current meets the load requirements and that the dropout voltage characteristics align with the minimum input-output differential.
