ISL80112IRAJZ-T7A

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

The ISL80112IRAJZ-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 2A and operates within an input voltage range up to 3.6V. The device features an adjustable output voltage starting from a minimum of 0.8V. It is housed in a 10-DFN (3x3 mm) surface-mount package with an exposed pad for thermal dissipation. Key electrical characteristics include a typical quiescent current of 10 mA and power supply rejection ratios ranging from 80 dB to 60 dB at 120 Hz.

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

Verify the specific suffix designation when ordering, as packaging variations such as tape-and-reel configurations may affect handling and storage requirements. Confirm that the component status aligns with current production schedules, noting that certain reel variants may have distinct lifecycle statuses compared to standard tube packages. Ensure compatibility with existing PCB footprints designed for the 10-DFN form factor before finalizing procurement decisions.

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

Select this regulator when application demands exceed the 1A limit of similar family members like the ISL80111 while maintaining a compact footprint. Evaluate the input-to-output voltage differential against the specified maximum dropout voltage at full load to ensure adequate headroom. Consider the thermal performance of the 10-DFN package relative to the expected ambient temperature and board copper area for effective heat dissipation during continuous operation.

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

This component belongs to the ISL8011x series of high-performance LDO regulators from Renesas. It shares architectural similarities with the ISL80111 but offers doubled output current capability. The series is characterized by low quiescent current consumption and robust transient response, making it suitable for space-constrained portable electronics where efficiency and size are critical design parameters.

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

Publicly confirmed substitute part numbers for the discontinued ISL80112IRAJZ-T7A include the ISL80112IRAJZ-T variant. Verify pinout and electrical specifications match exactly before substitution. Other family members like the ISL80112IRAJZ may serve as alternatives if packaging differences are acceptable.
