AN80L34RMSTX

Overview

The AN80L34RMSTX is a positive output, low dropout voltage regulator from the AN80LxxRMS series by Panasonic Electronic Components. It provides a fixed nominal output voltage of 3.4 V with a tolerance of ±3%. The device supports a maximum output current of 150 mA and operates within an input supply voltage range of 3.8 V to 14.5 V. It features a minimum input-to-output voltage difference of 0.4 V max at full load. The component includes a built-in reset function terminal that is active high, along with overcurrent limit and rush current prevention circuits. It is housed in a MINI-5D surface-mount package.

Feature Summary

• Integrated reset function terminal for system monitoring
• Built-in overcurrent limit circuit for protection
• Rush current prevention circuit during input voltage rise
• Surface-mount MINI-5D package for miniaturization

Applications

• Cellular phones
• PHS devices
• Analog cordless phones
• Small sized portable equipment

Procurement Notes

Verify the specific marking code BM on the component body to confirm the 3.4 V output variant. Ensure the ordering suffix matches the required tape-and-reel configuration if automated assembly is planned. Confirm the manufacturer source is Panasonic Semiconductor or authorized distributors to avoid counterfeit parts. Check datasheet revisions for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this regulator when a stable 3.4 V rail is required for low-power portable electronics. The MINI-5D package is suitable for space-constrained designs. Consider the 0.4 V dropout characteristic against the minimum available input voltage in the application. The integrated reset function simplifies external logic requirements for power-on sequencing. Verify thermal dissipation capabilities under maximum load conditions within the operating temperature range.

Part Context

The AN80L34RMSTX belongs to the AN80LxxRMS series, which comprises 20 classifications of fixed output voltages ranging from 1.8 V to 5.2 V. This series is designed as a 0.15 A low dropout regulator with a reset function. The 'RMS' suffix indicates the surface-mount MINI-5D package type. Other variants in the series share identical pinouts and protection features but differ in nominal output voltage and corresponding marking codes.

Replacement Considerations

Direct substitutes within the same series include AN80L33RMS (3.3 V) and AN80L35RMS (3.5 V) if voltage tolerance allows. Cross-series replacements require matching the 150 mA current rating, 3-pin MINI-5D package, and reset functionality. Verify pin compatibility and electrical characteristics before substitution.
