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

The ISL9011IRNCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics under the Intersil brand. It features two positive fixed output channels with current ratings of 150 mA and 300 mA. The device operates within an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages of 3.3 V and 1.8 V. Packaged in a 10-lead DFN (3x3 mm) surface-mount format, it supports operation from -40°C to +85°C. Key electrical specifications include a typical dropout voltage of 250 mV at 300 mA, line regulation of 0.2%/V, load regulation of 1%, and voltage accuracy of ±1.8%.
