LP3470IM5X-3.08/NOPB

Supervisors Overview

The LP3470IM5X-3.08/NOPB is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 3.08V with a maximum load current of 150mA. The device operates from an input voltage range up to 6V and features ultra-low quiescent current, typically 2µA in active mode and 0.5µA in shutdown mode. It includes internal protection mechanisms such as thermal shutdown and current limiting. The component is housed in a SOT-23-5 package, suitable for space-constrained portable applications requiring stable power supply.

Supervisors Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to confirm output voltage accuracy and package type. Ensure compatibility with your system's input voltage range and thermal requirements. Cross-reference with authorized distributors to confirm authenticity and avoid counterfeit components. Check for any recent lifecycle status changes or obsolescence notices directly from the manufacturer.

Supervisors Selection Notes

Select this component when a fixed 3.08V output is required with minimal quiescent current draw. Consider its 150mA load capability and 6V maximum input voltage limits. Evaluate thermal performance based on expected ambient temperatures and PCB copper area for heat dissipation. Compare dropout voltage characteristics against your minimum input-output differential requirements.

Supervisors Part Context
