Frequently Asked Questions

What output voltage and current does the TPS7A0531PDBVT provide?

The TPS7A0531PDBVT delivers a fixed 3.1 V output voltage at up to 200 mA continuous output current, making it suitable for powering low-voltage microcontrollers and sensors in portable designs.

How low is the dropout voltage on the TPS7A0531PDBVT under full load?

The typical dropout voltage is 204 mV at 200 mA load, with a maximum of 308 mV, allowing the device to regulate from input voltages as low as 3.6 V down to the 3.1 V output.

Which battery-powered applications benefit most from using the TPS7A0531PDBVT?

Applications running from single-cell Li-ion batteries (nominally 3.6 V to 4.2 V) benefit most because the low 204 mV dropout extends usable battery life by maintaining regulation deeper into the discharge curve, supporting IoT sensors, wearables, and handheld instruments drawing under 200 mA.

When would you choose the TPS7A0531PDBVT over an adjustable LDO for a 3.1 V rail?

A fixed-output LDO like the TPS7A0531PDBVT eliminates the two external feedback resistors required by adjustable regulators, reducing BOM count and PCB area in a 5-pin SOT-23 footprint, which is ideal when the 3.1 V setpoint is permanent and board space is under 2 mm x 2 mm.
