ISL80101IR18Z-TK

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

The ISL80101IR18Z-TK is a high-performance, single-output low dropout (LDO) linear regulator manufactured by Intersil. It delivers a fixed 1.8V output at up to 1A load current with an input voltage range of 2.2V to 6V. The device features a typical dropout voltage of 90mV at full load and maintains ±2% output accuracy across line, load, and temperature variations (-40°C to +125°C). It includes programmable current limiting, soft-start capability, and power-good signaling within a compact 10-lead DFN package.
