ISL78302AARJRZ

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

The ISL78302AARJRZ is a dual-channel low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages of 2.6 V and 2.8 V. Each channel supports a maximum output current of 300 mA with a typical dropout voltage of 250 mV. The device features a quiescent current of 47 µA and achieves a typical power supply rejection ratio (PSRR) of 90 dB. It is housed in a 10-lead DFN package and is rated for operation between -40°C and +105°C.
