Quiet LDO for an analog rail

Edit

After the buck, a low-noise LDO for the ADC, IMU, or microphone. PSRR and noise density matter; dropout at your current is the other number.

Starting part numbers

From the local map. These are examples, not the live result list.

  • ADP151AUJZ-3.3-R7

    Analog Devices

    Small, quiet enough for many sensors.

  • TPS7A4701RGWR

    Texas Instruments

    Ultra-low noise, the usual analog rail.

Live parts

On-demand from Nexar and/or DigiKey. Nothing here is a catalog Byuse owns. Specs appear only if the API returned them.

No distributor key is set. Browsing still works. To see live parts, add one of these pairs to .env.local and restart the dev server:

  • NEXAR_CLIENT_ID
  • NEXAR_CLIENT_SECRET
  • DIGIKEY_CLIENT_ID
  • DIGIKEY_CLIENT_SECRET

Nexar needs NEXAR_CLIENT_ID and NEXAR_CLIENT_SECRET. DigiKey needs DIGIKEY_CLIENT_ID and DIGIKEY_CLIENT_SECRET.
