ISL9008IEHZ-T

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

The ISL9008IEHZ-T is a single-output fixed low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.75 V with a maximum continuous output current of 150 mA. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 250 mV, reaching a maximum of 400 mV at full load. It maintains a load regulation of 0.1% and includes thermal protection mechanisms. The component is housed in a compact SC-70-5 surface-mount package and is rated for operation across an extended temperature range from -40°C to +85°C.
