ISL78302AARJRZ-T

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

The ISL78302AARJRZ-T is a dual low-dropout (LDO) voltage regulator from the ISL78302A series, manufactured by Renesas Electronics Corporation. It features two independent outputs capable of sourcing 300mA each, with fixed output voltages including options such as 2.6V, 2.8V, and 2.9V. The device operates within an input voltage range of 2.3V to 6.5V and maintains a typical quiescent current of 47µA when active. It offers high power supply rejection ratio (PSRR) of 90dB at 1kHz and low output noise. Packaged in a 10-DFN (3x3mm) surface-mount format, it is AEC-Q100 qualified for automotive applications and rated for operation between -40°C and +105°C.
