2V fixed rail, 300 nA Iq — what this LDO is for
The Texas Instruments TPS7A0320PDBVR is a single-output, positive-voltage LDO regulator that delivers a fixed 2V output at up to 200 mA. Its headline feature is a quiescent current of just 300 nA, which makes it a fit for battery-powered or always-on loads where every microamp counts — think IoT sensor nodes, wearable electronics, or standby rails in automotive modules. The output is fixed at 2V, so no external resistor divider is needed; just an input cap and an output cap and it regulates.
Temperature range and package — field-fit check
It comes in a SOT-23-5 surface-mount package.
Sourcing — active, quoted to order
For volume production or BOM-freeze planning, this part carries no near-term obsolescence risk.
