ISL80505IRAJZ-T

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

The ISL80505IRAJZ-T is a single-output Low Dropout (LDO) voltage regulator from Renesas Electronics Corporation, capable of sourcing up to 500mA output current. It operates with input voltages ranging from 1.8V to 6V and provides an adjustable output voltage between 0.8V and 5.5V. The device features a typical dropout voltage of 45mV at full load and offers high power supply rejection ratio (PSRR) performance. It includes built-in protection mechanisms such as overcurrent and thermal shutdown, ensuring reliable operation across a wide temperature range of -40°C to +125°C.
