LM4041DH5TA Integrated Circuits (ICs)

The LM4041DH5TA is a precision shunt voltage regulation device used in power supplies, particularly those based on SMPS topologies. It is a member of the LM4041 family of voltage references, which are intended for use as low-voltage references in a wide range of power management circuits. The LM4041DH5TA is designed to deliver stable, accurate output voltages over a wide range of temperatures and operating conditions with minimal perturbation in response to load, voltage and temperature changes. The LM4041DH5TA is a fixed output Regulator with no external adjustments required and is housed in a SOT-23 package. It is specified for operation over the temperature range of -40°C to +85°C.

The LM4041DH5TA is an adjustable shunt voltage regulation device. It is composed of an integrated circuit (IC) with power transistors and diodes to regulate voltage. The LM4041DH5TA is equipped with a resistor, an amplifier, and a PNP power transistor to function as an adjustable shunt regulator. When the input voltage reaches the reference voltage, the internal transistor turns off, thus preventing current from flowing through the regulator. This reduces wasted power and improves the overall efficiency of the power supply. The LM4041DH5TA is primarily used as a reference voltage in switching power supplies, but can also be used in applications such as battery charging, low-voltage supervision and level shifting.

The LM4041DH5TA has an adjustable reference voltage range from 2.25V to 5.50V in 8 standard values, resulting in excellent performance. The reference voltage is adjustable with an external resistor connected to the “REFADJ” pin of the IC. It is capable of providing up to 50mA of load current with a load regulation of 0.2%. Its dynamic output impedance is also very low, with an output impedance of less than 10mΩ, which helps to minimize voltage droop due to heavy loading.

The LM4041DH5TA is designed for use in a wide range of applications. It is used as a reference voltage in switching power supplies, linear voltage regulators, optical storage device power supplies, medicare power supplies and general power management applications. It is also useful for providing a reference voltage for battery charging circuits and for low-voltage supervision of digital logic circuits. In addition, it can be used as an adjustable level shifter.

In summary, the LM4041DH5TA is a versatile voltage reference device designed for use in a wide range of applications. It features a wide adjustable reference voltage range, low output impedance, and excellent load regulation, making it a suitable choice for power supply design. Its compact SOT-23 package, adjustable reference voltage range, low output impedance and excellent load regulation, makes the LM4041DH5TA ideal for use in a wide variety of power supply applications.
