ISL80510IRAJZ

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

The ISL80510IRAJZ is a single-output, positive adjustable CMOS Low Dropout (LDO) voltage regulator manufactured by Renesas Electronics. It supports an input voltage range from 2.2 V to 6 V and provides an adjustable output voltage between 800 mV and 5.5 V with a maximum continuous output current of 1 A. The device features a typical dropout voltage of 130 mV at full load and offers high power supply rejection ratio (PSRR) performance. It includes integrated protection mechanisms such as overcurrent limiting and thermal shutdown, ensuring reliable operation across an extended industrial temperature range of -40°C to +125°C.

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

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the component meets RoHS compliance requirements if mandated by your project specifications. Check for any recent Product Change Notices (PCNs) regarding pinout or electrical parameter updates before finalizing procurement orders.

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

Select this component when a single-channel LDO with 1 A output capability is required. Ensure the input voltage remains within the 2.2 V to 6 V limit and that the desired output voltage falls between 800 mV and 5.5 V. Consider the thermal dissipation capabilities of the 8-DFN package relative to the expected ambient temperature and load current to maintain safe operating temperatures.

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

This part belongs to the ISL805xx series of high-performance LDOs from Renesas. It shares architectural similarities with other members like the ISL80505 but differs primarily in output current capacity. The series is designed for applications demanding low noise and fast transient response in compact form factors.

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

Direct substitutes include the ISL80510IRAJZ-T7A, which offers identical electrical specifications but utilizes tape-and-reel packaging instead of trays. Verify compatibility with existing board layouts and thermal management strategies when switching packaging types.
