ISL9021IRUBZ-T

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

The ISL9021IRUBZ-T is a fixed-output linear voltage regulator (LDO) manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3.0 V with a maximum continuous output current of 250 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 150 mV, with a maximum specified at 250 mV under full load. It utilizes a 6-UTDFN (1.6x1.6 mm) surface-mount package. The component supports an operating temperature range from -40°C to +85°C and includes integrated protection mechanisms such as overcurrent, thermal shutdown, reverse polarity, short circuit, and soft-start functionality.
