FAQs

What is ADP7142AUJZ-R7?

The ADP7142AUJZ-R7 is a low-noise, low-dropout (LDO) voltage regulator designed by Analog Devices. It is specifically designed for applications requiring a stable and precise voltage supply with minimal noise and low dropout voltage, such as noise-sensitive analog circuits, RF components, and precision sensor systems.

How Does ADP7142AUJZ-R7 Work?

The ADP7142AUJZ-R7 operates as a linear voltage regulator that regulates the input voltage to a stable output voltage with low noise and low dropout. It accepts a higher input voltage and regulates it to a lower, precise output voltage while minimizing voltage fluctuations and noise on the output.

How Many Pins does ADP7142AUJZ-R7 have and What are the Functions of the Pinout Configuration?

The ADP7142AUJZ-R7 is packaged in a small, 5-lead TSOT (Thin Small Outline Transistor) package. The pinout configuration includes:

  • VOUT: Output voltage pin.
  • GND: Ground pin.
  • VIN: Input voltage pin.
  • NC: No-connect pin (not internally connected).
  • BP: Bypass pin for connecting an external bypass capacitor.

What are the Pros and Cons of ADP7142AUJZ-R7?

Pros:

  • Low Noise: Provides a stable output voltage with minimal noise, suitable for noise-sensitive applications.
  • Low Dropout: Operates with low dropout voltage, maximizing efficiency.
  • Small Package: The 5-lead TSOT package is compact and space-efficient.
  • Overcurrent Protection: Includes overcurrent protection to safeguard the regulator and connected components.
  • Low Quiescent Current: Operates with low quiescent current for energy efficiency.

Cons:

  • Limited Current Capability: May have a lower current output compared to higher-power regulators.
  • Heat Dissipation: May require a heat sink or thermal management for high-power applications.
  • External Components: External capacitors may be required for stability and noise filtering.

Are There Any Equivalents/Alternatives to ADP7142AUJZ-R7 for Recommendation?

  • The MIC5205 from Microchip Technology is an equivalent LDO voltage regulator.
  • Alternatives to the ADP7142AUJZ-R7 include the LT1763 from Analog Devices and the LM2937 from Texas Instruments.
