Frequently Asked Questions
What is the dropout voltage of TLV74310PDBVR and why does it matter for battery-powered designs?
TLV74310PDBVR has a typical dropout voltage of only 122 mV, which means the regulator continues to provide a stable 1.0 V output even when the input voltage drops to just 1.122 V. This is critical in Li-ion battery designs because it allows the system to operate deeper into the battery discharge curve, extending device runtime by up to 20% compared to regulators with 300 mV dropout.
Which input voltage sources are compatible with TLV74310PDBVR?
TLV74310PDBVR accepts input voltages from 1.4 V to 5.5 V with an absolute maximum of 6 V. This range covers single-cell Li-ion batteries (2.7 V to 4.2 V), USB 5 V rails, and 3.3 V system buses, making it a flexible LDO for a wide variety of embedded and portable applications.
How much current can TLV74310PDBVR supply, and is it suitable for microcontroller power rails?
TLV74310PDBVR supplies up to 300 mA of continuous output current at a fixed 1.0 V output. This is sufficient to power low-voltage microcontrollers, FPGAs with 1.0 V core rails, and LPDDR memory in ultra-low-power systems, particularly in IoT nodes and wearable devices.
What package does TLV74310PDBVR use and is it RoHS compliant?
TLV74310PDBVR is housed in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5) with a body size of approximately 1.6 mm x 2.9 mm. It is fully Pb-free and RoHS-compliant (JESD-609 code e3), suitable for modern green electronics manufacturing processes.
