Details

The ADP7104ARDZ is a low-noise, low-dropout (LDO) voltage regulator manufactured by Analog Devices. It is designed to provide a stable output voltage with a low dropout voltage, making it ideal for noise-sensitive applications such as RF signal processing, precision data acquisition, and power management in portable devices.With an input voltage range of 2.5V to 20V and an output voltage range of 1.2V to 16V, the ADP7104ARDZ offers flexibility in powering a wide range of devices. It features a maximum output current of 400mA, making it suitable for small to medium-sized loads.The regulator has a high PSRR (power supply rejection ratio) of 75dB at 1kHz, ensuring that any variations in the input voltage do not affect the output voltage. It also has a low dropout voltage of 190mV at 100mA, minimizing power loss and improving efficiency.Additional features of the ADP7104ARDZ include thermal overload and short-circuit protection, as well as a shutdown mode to conserve power when the regulator is not in use. It is available in a small 5-lead TSOT package, making it easy to incorporate into space-constrained designs.

FAQs

What is ADP7104ARDZ?

The ADP7104ARDZ is a low dropout (LDO) voltage regulator designed by Analog Devices. It is a high-precision, low-power solution suitable for applications requiring stable and accurate voltage regulation, such as battery-powered devices, portable instruments, and precision measurement systems.

How Does ADP7104ARDZ Work?

The ADP7104ARDZ operates as a low dropout voltage regulator, providing a stable output voltage even when the input voltage is close to the desired output voltage. It uses a precision bandgap reference and a feedback loop to regulate the output voltage, ensuring minimal voltage variation under different load conditions. The LDO features low dropout voltage and low quiescent current, making it suitable for battery-operated applications.

How Many Pins does ADP7104ARDZ have and What are the Functions of the Pinout Configuration?

The ADP7104ARDZ is housed in a 8-lead SOIC package. The pinout configuration includes:

  • VIN: Input voltage pin.
  • GND: Ground pin.
  • VOUT: Output voltage pin.
  • NC: No-connect pin.
  • EN: Enable pin for turning the regulator on or off.
  • ADJ: Adjustment pin for fine-tuning the output voltage.

What are the Pros and Cons of ADP7104ARDZ?

Pros:

  • High Precision: Provides accurate voltage regulation for sensitive applications.
  • Low Dropout Voltage: Maintains regulation even with small input-output voltage differentials.
  • Low Quiescent Current: Minimizes power consumption when the load is light.
  • Thermal Shutdown and Current Limit: Built-in protection features for enhanced reliability.
  • Compact Package: The 8-lead SOIC package offers space-efficient integration.

Cons:

  • Heat Dissipation: May require a heat sink for high power dissipation applications.
  • Cost: Higher precision and low dropout performance may result in a higher cost compared to standard regulators.
  • External Components: May require external capacitors for stability and noise filtering.

Are There Any Equivalents/Alternatives to ADP7104ARDZ for Recommendation?

  • The TPS7A47 from Texas Instruments is a comparable LDO voltage regulator with similar specifications.
  • Alternatives to the ADP7104ARDZ include the LT1761 from Analog Devices and the MAX8881 from Maxim Integrated.
