What are the key features of TPS7A1111PDRVR?
- Ultra-low 130 mV dropout voltage at 500 mA output enables efficient regulation from nearly equal input rails, maximizing battery runtime
- Low quiescent current in the microamp range preserves battery life in always-on IoT and wearable applications
- Compact 6-pin SOT-23 (SOT-23-6) package with fixed output voltage simplifies BOM and PCB layout for space-constrained designs
What is TPS7A1111PDRVR used for?
TPS7A1111PDRVR is designed for battery-powered wearables, IoT sensor nodes, and Bluetooth Low Energy devices that need a stable regulated rail from a single-cell Li-ion battery discharging from 3.0 V to 2.8 V while maintaining a 2.8 V or lower output. Its 130 mV dropout and microamp quiescent current extend device runtime by weeks in always-on standby modes. The device also suits portable medical monitors and handheld test equipment where a clean, noise-free voltage rail is required from a low-headroom 3.3 V system bus.

Frequently Asked Questions
What is the dropout voltage of TPS7A1111PDRVR at full 500 mA output current?
TPS7A1111PDRVR achieves a maximum dropout voltage of 140 mV at the full 500 mA load, with a nominal value of 130 mV. This ultra-low dropout means the device can maintain regulation with an input-to-output differential of less than 0.15 V, which is critical for single-cell Li-ion batteries discharging toward end-of-life at 2.7 V to 3.0 V.
What input voltage range does TPS7A1111PDRVR support, and can it work directly from a 3.3 V bus?
TPS7A1111PDRVR accepts input voltages from 1.6 V minimum to 3.3 V maximum continuous, with an absolute maximum of 3.6 V. It can operate directly from a 3.3 V bus to generate a lower fixed output rail, and its 130 mV dropout makes it practical for generating 3.0 V or 2.8 V from that rail with minimal power loss.
How does TPS7A1111PDRVR compare to TPS7A20 for low-power IoT applications?
TPS7A1111PDRVR offers a lower 130 mV dropout compared to typical 200 mV for TPS7A20, making it more efficient when the input-output headroom is tight, such as in a 3.3 V to 3.0 V regulation scenario. Both parts target IoT low-power use cases, but TPS7A1111PDRVR in the 6-pin SOT-23 package suits designs with very limited PCB area and maximum 3.3 V input constraints.
What output current does TPS7A1111PDRVR support, and what happens if the load exceeds that limit?
TPS7A1111PDRVR is rated for up to 500 mA continuous output current. If the load current exceeds this threshold or if a short-circuit condition occurs, the built-in current limiting and thermal shutdown protection engage to protect the device and system. The regulator recovers automatically once the fault condition is removed and the die temperature drops below the reset threshold.
