Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for LT3080IST#PBF

LT3080IST#PBF

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

The LT3080IST#PBF is a 1.1A adjustable low dropout linear regulator in a 3-lead SOT-223 package. It features a single resistor programming architecture with a precision 10µA SET pin current, allowing output voltage adjustment from 0V to 36V. The device operates with an input voltage range of 1.2V to 36V and maintains stability with a minimum 2.2µF ceramic output capacitor. Key electrical specifications include a typical dropout voltage of 350mV at 1.1A load, line regulation of 0.003 mV/V, and load regulation of 0.6 mV. It provides internal protection against short circuits and overtemperature conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

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

Verify the component marking '3080' on the SOT-223 package to confirm authenticity. Ensure the ordering suffix matches the required temperature grade and lead finish. Confirm that the specific revision level aligns with your design requirements before finalizing procurement orders.

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

Select this part when a high-current linear regulator requires simple voltage setting via a single resistor. The SOT-223 package is suitable for applications where through-hole mounting is not mandatory but higher current handling than smaller surface mount packages is needed. Consider the 350mV dropout specification relative to your minimum input-output differential requirements.

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

This component belongs to the LT3080 family of adjustable 1.1A low dropout regulators manufactured by Analog Devices. The family includes various packages such as DFN, MSOP, DD-Pak, TO-220, and SOT-223. The LT3080 series is distinguished by its unique architecture using a precision current source reference rather than a traditional voltage reference divider.
