ISL78307FBEAZ-T

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

The ISL78307FBEAZ-T is a linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed positive output voltage of 3.3 V with a maximum output current capability of 50 mA. The device supports an input voltage range from 6 V to 40 V and operates within an extended temperature range of -40 °C to +125 °C. It features a low quiescent current of 18 µA, line regulation of 0.04 %, and load regulation of 0.25 %. The component is housed in an 8-lead SOIC package with an exposed pad (SOIC-8-EP) for surface-mount installation.
