ISL9000IRJCZ-T

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

The ISL9000IRJCZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed output voltages of 1.8V and 2.8V, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 32µA and power supply rejection ratio (PSRR) ranging from 90dB to 50dB across frequencies of 1kHz to 100kHz. It is housed in a 10-DFN (3x3mm) package with exposed pad.
