ISL78302AARLLZ-T7A

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

The ISL78302AARLLZ-T7A is a high-performance dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides two independent positive fixed outputs, each capable of sourcing up to 300mA. The device features a maximum input voltage of 6.5V and operates within an ambient temperature range of -40°C to +105°C. Key electrical specifications include a typical dropout voltage of 0.23V at 300mA load and a quiescent current of 36µA. It is housed in a compact 10-DFN (3x3mm) package with an exposed pad for thermal dissipation.
