LP38798SD-ADJ/NOPB Typical application Circuitry

The LP38798SD-ADJ/NOPB is a high-performance, ultra-low noise and high PSRR LDO (Low Drop-Out) voltage regulator. This chip is manufactured by Texas Instruments and provides a solution for applications requiring low noise, high precision, and excellent power supply rejection ratio.

Various application scenarios for the LP38798SD-ADJ/NOPB include precision instrumentation, RF, and wireless communication where clean voltage rails are necessary. The LP38798SD-ADJ/NOPB is also ideal for powering analog circuits that need to have a low noise and stable power supply.

The LP38798SD-ADJ/NOPB offers an adjustable output voltage from 1.8V to 5.5V with an accuracy of ±2%. The device has an impressive low noise of 6.5µVRMS (10 Hz to 100 kHz), high PSRR of 70dB at 10kHz, and fast start-up time of 120µs.

Now let's discuss an example circuit design for a precision instrumentation system:

1. Input Voltage (IN, Pin 5): Connect your power source to this pin. Ensure it's within the specified operating voltage range. Between this pin and ground, a pin input capacitor (Cin) should be positioned for reliable operation.

2. Ground (GND, Pin 2): The ground pin should be connected to your system's ground.

3. Enable Pin (EN, Pin 4): This pin allows you to turn on/off the LP38798SD-ADJ/NOPB. Applying a logic high or low will enable or disable the device.

4. Adjust Pin (ADJ, Pin 3): The output voltage is set via the ADJ pin. Connect a resistor divider from the output to the ADJ pin to set the desired voltage.

5. Output (OUT, Pin 1): This is where the regulated voltage is available. Connect the load to this pin. An output capacitor (Cout) is typically used between this pin and ground to improve transient response and stability.

Designing with the LP38798SD-ADJ/NOPB involves considering the layout, the thermal conditions, and the input and output capacitors. For the layout, ensure to minimize the loop area formed by the input capacitor, the device, and the output capacitor to reduce noise and enhance stability. The thermal design should ensure that the heat can be effectively dissipated to prevent the chip from overheating. Performance and stability depend on the input and output capacitors being chosen carefully. As per the datasheet, ceramic capacitors with an X7R or X5R dielectric are recommended for best results.
