ISL9008AIENZ-T

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

The ISL9008AIENZ-T is a fixed-output low noise Low Dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3.3 V with a maximum load current capability 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 0.3 V at full load. It is housed in a SC-70-5 surface-mount package and is rated for operation over an extended temperature range from -40°C to +85°C.
