LP3878MR-ADJ/NOPB

The LP3878-ADJ is an 800-mA, adjustable output, voltage regulator designed to provide high performance and low noise in applications requiring output voltages as low as 1 V.

Using an optimized VIP (Vertically Integrated PNP) process, the LP3878-ADJ delivers superior performance:

  • Ground Pin Current: Typically 5.5 mA at 800-mA load, and 180 µA at 100-µA load.
  • Low Power Shutdown: The LP3878-ADJ draws less than 10-µA quiescent current when the SHUTDOWN pin is pulled low.
  • Precision Output: Ensured output voltage accuracy is 1% at room temperature.
  • Low Noise: Broadband output noise is only 18 µV (typical) with a 10-nF bypass capacitor.
