Product details

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.

Frequently asked questions

Is TPS7A0320PDBVR equivalent to TPS7A0220PDBVR?

Both are fixed 2V output LDOs in the same SOT-23-5 package from TI's TPS7A02 family. The TPS7A0320PDBVR is a higher-performance variant with a quiescent current of 300 nA versus the TPS7A0220PDBVR's 25 nA Iq — the 0320 trades slightly higher quiescent draw for improved PSRR and transient response. Pin-compatible, so a direct swap on the board if the application can tolerate the difference in Iq.
