L6932D1.5TR Application Field and Working Principle

As one of the voltage regulator products, the L6932D1.5TR is a monolithic, low dropout, dual mode, adjustable and fixed output linear (LDO) voltage regulator, with a regulated output of 1.5V. It integrates internal protection circuitry, including thermal shutdown and current limit, allowing it to be used in a diverse range of applications. In this article, we will discuss the application field and working principle of this PMIC voltage regulator.

Application Field of L6932D1.5TR:

The L6932D1.5TR is an effective, cost-efficient and stable voltage regulator, which operates within a wide operating temperature range (from -40℃ to +125℃). Therefore, it is suitable for various applications, such as:

• Automotive electronics, including oil gauge, airbag, anti-lock braking systems and navigation systems.
• Industrial control, such as actuator, transformer and motor.
• Monitoring and measurement systems, including temperature and pressure sensing.
• Communication systems, including LAN, xDSL and cellphones.
• Medical instruments, including CT, EKG and ECG.

Working Principle of L6932D1.5TR:

The L6932D1.5TR is a low dropout, dual mode, adjustable and fixed output linear (LDO) voltage regulator, which regulates the output voltage over a wide input voltage range. The input voltage can range from 1.2V to 20V, while the output voltage can be fine-tuned between 1.2V and VIN, or set at 1.5V.

When set to 1.5V, the regulated voltage output remains constant regardless of the input voltage. When the fine-tuning function is enabled, the output voltage may vary according to the input voltage. The output voltage can be adjusted through an external resistor divider impedance.

The L6932D1.5TR is also equipped with internal protection circuitry, including current limit, thermal shutdown and input under-voltage lock out. These protection components help to continuously monitor the voltage level and avoid any overloading or overheating of the voltage regulator.

The L6932D1.5TR is a highly efficient and cost-effective PMIC voltage regulator. Its features, including wide operating temperature range, low dropout, dual mode operation, adjustable and fixed output make it an ideal solution for a variety of industrial, automotive and medical applications.
