TLV74328PDBVR

Introduction to TLV74328PDBVR

The TLV74328PDBVR is a linear voltage regulator developed by Texas Instruments. It is an easy-to-use and cost effective part, as it is based on TI’s simplified voltage regulation system. It boasts a low quiescent current (23 µA typical) and an adjustable output voltage range of 0.5V to 6V.

Application Field of TLV74328PDBVR

The TLV74328PDBVR linear voltage regulator is designed for a broad range of applications, spanning from consumer electronics to industrial systems. It can be used in various fields where the regulated output voltage is required to be within the 0.5V to 6V range. Examples include voice and data communications services, automotive electronics, industrial equipment, office automation and consumer medical devices.

The TLV74328PDBVR also has a thermal shutdown feature, which limits the junction temperature of the device to a safe level, in case of excessive loading or an external thermal hazard. This feature ensures reliable operation and enhanced system reliability, even in thermal-hazard-prone applications.

Working Principle of the TLV74328PDBVR

The working principle of the TLV74328PDBVR is centered around the linear regulation of the output voltage. The device consists of a comparator, and a control circuit. The comparator compares the input voltage, with a voltage reference. Depending on the result of the comparison, the control circuit then adjusts the output voltage to the desired value. This is done by adjusting the resistances connected in series with the input and output of the regulator.

The control circuit also monitors the load current of the regulator, and provides current limiting as needed. This helps to reduce the thermal stress and helps maintain system reliability. In addition, the control circuit also features over-voltage protection, which ensures that the output voltage never exceeds the specified maximum safe voltage level.
