ISL80102IRAJZ-TK

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

The ISL80102IRAJZ-TK is a low voltage, high-current single-output linear regulator from the Renesas ISL80102 series. It provides a fixed positive output of 3.3V with a maximum continuous output current of 2A. The device operates within an input voltage range of 2.2V to 6V and utilizes a DFN-10 package measuring 3x3 mm. Key electrical specifications include a typical dropout voltage of 81 mV at full load, a line regulation of 0.1%, and a load regulation of -0.6%. It supports an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix 'TK' indicates tape and reel packaging when sourcing components. Confirm that the fixed 3.3V output variant matches the system requirement, as adjustable versions exist within the same family. Ensure compatibility with RoHS compliance standards and check for any recent product change notices regarding manufacturing location or material composition updates.

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

Select this component when a fixed 3.3V rail is required with up to 2A load capability. Consider the 81 mV dropout voltage for battery-powered applications where headroom is limited. Evaluate thermal performance based on the DFN-10 package size and expected ambient temperatures. Compare against adjustable variants if system flexibility for different voltage levels is needed.

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

This part belongs to the ISL80102/ISL80103 family of high-performance linear regulators manufactured by Renesas Electronics. The series is designed using submicron BiCMOS technology to deliver superior analog performance and low static current compared to traditional bipolar LDOs. The ISL80102 specifically targets 2A applications, while the ISL80103 handles 3A loads, both sharing similar pinouts and feature sets.

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

Direct substitutes within the same family include the adjustable version ISL80102IRAJZ-TK. For fixed voltage requirements, verify availability of other fixed output options such as ISL80102IR18Z-TK (1.8V) or ISL80102IR25Z-TK (2.5V). Cross-reference datasheets to ensure identical pin configurations and thermal characteristics before substitution.
