ISL80102IRAJZ-T7A

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

The ISL80102IRAJZ-T7A is a single-output adjustable low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It supports an input voltage range from 2.2 V to 6 V and delivers up to 2 A of output current. The device provides an adjustable output voltage between 800 mV and 5.5 V. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 55 dB, a maximum dropout voltage of 121 mV, and line regulation of 0.1%. It operates within a temperature range of -40°C to +125°C and is housed in a 10-lead DFN package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Check for obsolescence notices as the product lifecycle status may indicate end-of-life phases. Ensure proper handling procedures are followed due to surface mount packaging requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a single adjustable output is required with high current capability up to 2 A. Consider the 2.2 V minimum input voltage constraint against your source supply. Evaluate the 10-DFN package size for PCB space limitations. Compare PSRR and dropout characteristics against alternative LDOs if noise sensitivity or efficiency is critical.
