Details

The LP3869x-ADJ low-dropout CMOS linear regulators provide 2% precision reference voltage, extremely low dropout voltage (250 mV at 500-mA load current, VOUT = 5 V), and excellent AC performance using ultra-low equivalent series resistance (ESR) ceramic output capacitors.

The low thermal resistance of the WSON and SOT-223 packages allow use of the full operating current even in high ambient temperature environments.

The use of a PMOS power transistor means that no DC base drive current is required to bias it, thus allowing the GND-pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.

For all available packages, see the orderable addendum at the end of the data sheet.

FAQs

What is LP38693MP-ADJ/NOPB?

The LP38693MP-ADJ/NOPB is a low dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and regulated output voltage with low dropout voltage, making it suitable for applications requiring precise voltage regulation such as power management in various electronic devices.

How Does LP38693MP-ADJ/NOPB Work?

The LP38693MP-ADJ/NOPB operates by taking an input voltage, regulating it through a feedback loop, and providing a stable output voltage at a lower level. It utilizes a pass transistor that adjusts its resistance to maintain the desired output voltage even when the input voltage varies. The LDO design helps minimize power dissipation and noise for efficient voltage regulation.

How Many Pins does LP38693MP-ADJ/NOPB have and What are the Functions of the Pinout Configuration?

The LP38693MP-ADJ/NOPB is housed in a TO-220 package with 5 pins. The pinout configuration includes:

  • VIN: Input voltage pin.
  • VOUT: Regulated output voltage pin.
  • GND: Ground pin.
  • ADJ: Adjust pin for output voltage adjustment.
  • ON/OFF: On/Off control pin for enabling or disabling the regulator.

What are the Pros and Cons of LP38693MP-ADJ/NOPB?

Pros:

  • Low Dropout Voltage: Provides stable output even with small voltage differentials between input and output.
  • Low Noise: Offers clean and regulated output voltage suitable for noise-sensitive applications.
  • Thermal Shutdown: Built-in thermal shutdown protection for overtemperature conditions.
  • Current Limiting: Includes current limit protection for circuit and load safety.
  • Wide Input Voltage Range: Supports a wide input voltage range for versatility in various power supply applications.

Cons:

  • Heat Dissipation: May require a heat sink for high power dissipation applications.
  • Cost: Higher cost compared to non-regulated or less precise voltage regulation solutions.
  • External Capacitors: External capacitors may be required for stability and noise reduction depending on the application.

Are There Any Equivalents/Alternatives to LP38693MP-ADJ/NOPB for Recommendation?

  • The LM2940 from Texas Instruments is a similar LDO regulator providing voltage regulation with low dropout characteristics.
  • Alternatives to the LP38693MP-ADJ/NOPB include the LT1763 from Analog Devices and the ADP3336 from Analog Devices.
