ISL9014AIRKKZ

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

The ISL9014AIRKKZ is a dual low-dropout (LDO) linear voltage regulator from the Intersil ISL9014 series, housed in a 10-lead DFN (3x3 mm) package. It provides two fixed positive output voltages of 3.0V per channel with a maximum continuous output current of 300mA per regulator. The device features a typical quiescent current of 40µA and supports an input voltage range up to 6.5V. Key electrical characteristics include a maximum dropout voltage of 325mV at 300mA load and line regulation of 0.2%/V. It operates within a temperature range of -40°C to +85°C.
