PMIC: Voltage Regulators - Linear

The TLE42644GHTSA3 is a PMIC Voltage Regulator, Linear type, which is especially useful for applications in communications and the automotive industry. This type of voltage regulator is characterized by the lowest output resistance, low noise, and improved response time. The device is protected against short-circuit, overtemperature, and reverse polarity protection.

Main Features and Benefits

  • Wide operating temperature range: -40°C to +105°C
  • Low dropout voltage and low quiescent current
  • Low noise, high peak current and fast response time
  • Protection against over-temperature, short-circuit, and reverse polarity
  • TTL/CMOS compatible and low voltage differential
  • Small package size suitable for board-space-saving

Applications

  • Local on-card power supply
  • Communications equipment
  • Portable consumer electronics
  • Automotive electronics

Working Principle

In the simplest terms, the TLE42644GHTSA3 is an adjustable voltage regulator. It is an integrated circuit that maintains a constant output voltage regardless of input voltage variations or the output load. It works by comparing the voltage at its output terminal with a reference voltage in the form of a voltage divider which is controlled by the user. The difference between the two voltages is called the error voltage. This error voltage is used to control the gain of an amplifier, which then adjusts the output voltage to match the reference voltage. This feedback action ensures that the output voltage is held at the desired level.

The TLE42644GHTSA3 can be operated in either linear or switching modes. In linear mode, a voltage regulator is used to control the output voltage by varying its output resistance. This is done to maintain the output voltage at a constant level despite changes in input voltage and output load. In switching mode, the output voltage is switched on/off rapidly, resulting in a reduced quiescent current.

Conclusion

The TLE42644GHTSA3 is a high quality, linear voltage regulator that is especially useful for applications in communication systems and automotive electronics. It has a wide operating temperature range and offers low output resistance, low noise, and improved response time. Furthermore, it is protected against short-circuit, over-temperature, and reverse polarity protection, and has a TTL/CMOS compatible low voltage differential.
