LM2936QDTX-3.3/NOPB is a voltage regulator manufactured by Texas Instruments and classified as one of their PMIC (Power Management IC) linear voltage regulators. The LM2936QDTX-3.3/NOPB provides a voltage regulation of 3.3V, making it suitable for applications requiring a low-dropout and an LDO-level voltage regulation.

Application Field

The LM2936QDTX-3.3/NOPB is primarily used in mobile device as a power supply voltage regulator, such as in smartphones and tablets. The LM2936QDTX-3.3/NOPB is specifically designed to work within the 3V – 3.6V input voltage employed in many of today\'s mobile devices and it optimizes system efficiency and power management by offering a low-dropout (LDO) regulation level. It also has a higher output current capability and more accurate regulation than many other linear voltage regulators. In addition, the general purpose PMIC voltage regulator offers high-power performance, reliability, low power dissipation and small solution size. The LM2936QDTX-3.3/NOPB is also effectively used in a variety of non-mobile, 3V or 3.3V applications like POS systems, PMICs in routers, industrial systems, USB hubs, fan controllers, power supplies, DC motors, and security systems.

Working Principle

The LM2936QDTX-3.3/NOPB works as a linear voltage regulator, which is a device that seeks to maintain a constant output voltage while varying its input voltage. It is used to regulate the voltage provided by a power supply to to reduce it to a level suitable for use in electronic circuits. The LM2936QDTX-3.3/NOPB uses a series of series pass elements and a feedback loop to control the output voltage. It consists of an operational amplifier, an N-channel MOSFET pass transistor, and a series of resistors for voltage regulators.

The LM2936QDTX-3.3/NOPB provides its output voltage with a low-dropout (LDO) regulation level. Low drop-out refers to the amount of voltage that is dropped from the input voltage to the regulator\'s output voltage. It is the difference between the input voltage and the output voltage. The LM2936QDTX-3.3/NOPB typically has a low drop-out voltage of 200mV at 100mA of output current, making it suitable for applications requiring high efficiency.

The LM2936QDTX-3.3/NOPB has several features that help increase its efficiency and accuracy, such as thermal shutdown, under-voltage lockout (UVLO), and power good. Thermal shutdown is triggered if the die temperature of the LM2936QDTX-3.3/NOPB rises to a certain level, which helps prevent overheating and device failure. Under-voltage lockout (UVLO) automatically shuts off the power supply if it senses that the input voltage is below a certain threshold, preventing damage to the device. The power good signal indicates whether or not the output voltage is within its specified range and is sent to the power supply to disable it if the output voltage is too low.

The LM2936QDTX-3.3/NOPB has a wide temperature range and is certified with the environmental friendly qualification of GreenPbF. GreenPbF certification is a process by which Texas Instruments products conform to the highest environmental standards. It ensures that products meet industrial standards for compliance with accepted environmental practices.

The LM2936QDTX-3.3/NOPB is a versatile and reliable 3V to 3.3V voltage regulator designed for mobile and non-mobile applications. It provides a high-power, low-dropout regulation level, increased current capability and accuracy, and meets the highest environmental standards.
