ISL80113IRAJZ-T7A

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

The ISL80113IRAJZ-T7A is a single-output, positive adjustable linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a maximum output current of 3A and supports an input voltage range up to 5.5V. The device features an adjustable output voltage range from 0.8V to 5.5V. Key electrical specifications include a typical quiescent current of 10mA and a power supply rejection ratio (PSRR) ranging from 80dB to 60dB at 120Hz. It operates within a junction temperature range of -40°C to +125°C and is housed in a 10-VFDFN package with an exposed pad.

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

Verify the specific suffix T7A indicates tape-and-reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official datasheets prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinouts with latest Renesas documentation to avoid compatibility issues during PCB layout.

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

Select this component when high output current near 3A is required alongside low noise requirements. Consider the 10-DFN package constraints for thermal management and board space. Evaluate input-to-output voltage differential to ensure operation remains within dropout limits under maximum load conditions. Verify that the adjustable output range aligns with system voltage requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This LDO belongs to the ISL8011x family of high-performance regulators designed for portable and industrial applications. The series emphasizes low quiescent current and high PSRR to support noise-sensitive loads. Compared to fixed-output variants, the adjustable version offers flexibility in setting precise output voltages using external feedback resistors.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

ISL80113IRAJZ is the tube-packaged equivalent of the same functional device. ISL80111IRAJZ-T7A serves as a lower-current alternative if 1A output suffices. Verify pin compatibility and thermal characteristics before substituting with other LDO families.
