ISL78302AARGCZ

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

The ISL78302AARGCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides two independent positive fixed outputs of 1.8V and 2.7V, each capable of sourcing up to 300mA. The device operates with an input voltage range of 2.3V to 6.5V and features a typical quiescent current of 36µA. It offers high power supply rejection ratio (PSRR) ranging from 90dB at 1kHz to 50dB at 100kHz. The IC is housed in a 10-DFN (3x3mm) package with exposed pad and is rated for automotive temperatures from -40°C to +105°C.
