ISL9012IRFDZ

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

The ISL9012IRFDZ is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features two positive fixed output voltages of 2.5 V and 2 V, delivering maximum output currents of 150 mA and 300 mA respectively. The device operates with an input voltage range from 2.3 V to 6.5 V. Key electrical specifications include a maximum dropout voltage of 0.2 V at 150 mA and 0.5 V at 300 mA. It incorporates comprehensive protection mechanisms including overcurrent, thermal overload, soft-start, and under-voltage lockout (UVLO). The component is housed in a 10-DFN (3x3 mm) package with a bare pad and supports surface mount installation.
