Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021AIRUNZ-T7A

ISL9021AIRUNZ-T7A

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

The ISL9021AIRUNZ-T7A is a fixed-output low-dropout linear regulator manufactured by Renesas Electronics. It provides a stable 3.3 V output with a maximum continuous current of 250 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and maintains a typical dropout voltage of 150 mV at full load. It features a low quiescent current of 35 µA and high power supply rejection ratio (PSRR). The component is housed in a compact 6-UTDFN package measuring 1.6 x 1.6 mm, suitable for surface-mount applications across a temperature range of -40°C to +85°C.
