LP38841SX-1.5 Application Field and Working Principle

Linear voltage regulators are a great way to control voltage levels in electronic systems. The LP38841SX-1.5 is a high-performance synchronous step-down voltage regulator achieving up to 1.5A output current. Notable features include over temperature protection and adjustable output voltage. It is a cost-effective solution for all electronic applications requiring analog or digital control.

Features

  • High accuracy of reference voltage 1.21V (1%)
  • Shutdown current: 10nA
  • Low Dropout voltage
  • Low noise
  • Output voltage adjustable
  • Over temperature protection
  • Compact miniature size

Application Field

The LP38841SX-1.5 is ideal for applications requiring high current, low dropout voltage, and accurate voltage regulation. These include automotive systems, devices, wearable applications, and industrial systems. It is designed to achieve a power efficiency of 98% and quiet, low-noise performance at the same time. The adjustable output voltage can be easily adjusted by external resistor for high accuracy.

Working Principle

The LP38841SX-1.5 implements a high-performance synchronous step-down voltage regulator. An internal control loop of the device uses external components to set and monitor the output voltage. A voltage divider made of an external resistor and capacitor is used to set the output voltage. This voltage divider is connected to an internal bandgap reference circuit, which is used to compare the output voltage to a fixed reference voltage and adjust the output voltage as required. The output voltage can also be adjusted via an external resistor.

The voltage regulator also contains a low-dropout P-MOSFET, which is switched on and off to regulate the output voltage. When the P-MOSFET is on, it sinks current from the input voltage and drops voltage across it. The current drawn from the input is supplied to the output node. This process is repeated in cycles by the switching action of the P-MOSFET. The switching frequency is set by an internal oscillator and can be adjusted via an external resistor.

The LP38841SX-1.5 also implements over temperature protection circuitry, which prevents the output voltage from dropping if the device is overheated. The device will automatically shut down when the temperature reaches a certain level and the output voltage will be reset to the level specified by the voltage divider.

Conclusion

The LP38841SX-1.5 is a high-performance, cost-effective step-down voltage regulator suitable for a variety of applications. It offers adjustable output voltage and over temperature protection. The device is also small in size, allowing it to be used in a wide range of applications. With its high efficiency and quiet operation, this device is ideal for applications requiring accurate voltage regulation.
