Key Features
- Adjustable output from 0.8 V to 6 V covers wide range of digital core and I/O rail requirements in a single design
- 170 mV typical dropout voltage enables efficient low-headroom regulation from Li-ion battery or 3.3 V bus supplies
- 1 A output current in compact 8-pin SON package reduces PCB area versus discrete pass-transistor LDO implementations
Applications
The TPS7A8101DRBR is designed for powering digital processor cores, FPGAs, and DDR memory termination rails that require a programmable 0.8 V to 6 V output at up to 1 A. Its low 170 mV dropout voltage makes it an efficient post-regulator downstream of 3.3 V or 5 V switching converters in noise-sensitive RF and ADC power supply chains. Portable medical instruments and industrial handheld devices also benefit from its 2.2 V minimum input voltage, allowing direct regulation from a single-cell Li-ion or LiFePO4 battery.

Frequently Asked Questions
What input and output voltage range does the TPS7A8101DRBR support for battery-powered designs?
The TPS7A8101DRBR accepts input voltages from 2.2 V to 6.5 V and provides an adjustable output from 0.8 V to 6 V at up to 1 A. This range is directly compatible with single-cell Li-ion batteries (2.7 V to 4.2 V) and 3.3 V bus rails, making it a practical choice for portable devices requiring a regulated core or I/O supply.
How low is the dropout voltage of the TPS7A8101DRBR and why does it matter for efficiency?
The TPS7A8101DRBR has a typical dropout voltage of 170 mV and a maximum of 500 mV at 1 A. Low dropout is critical in battery-powered applications where input voltage is close to the desired output—for example, generating a 3.0 V rail from a 3.3 V bus allows the battery to discharge further, extending runtime by tens of minutes in typical consumer electronics.
What external components are needed to set the output voltage of the TPS7A8101DRBR?
Output voltage is set with 2 external resistors forming a feedback divider connected to the ADJ pin. For a 1.8 V output, typical resistor values are in the 100 kΩ range, producing a feedback current well below 10 µA to minimize output voltage error. A 1 µF ceramic output capacitor is sufficient for stability in most applications, keeping the total BOM small.
How does the TPS7A8101DRBR compare to the TPS7A20 series for FPGA core power in a compact layout?
Both devices offer adjustable LDO regulation, but the TPS7A8101DRBR provides 1 A in a smaller 8-pin SON (2 mm x 2 mm) footprint versus larger packages in the TPS7A20 family, which is advantageous when powering FPGA I/O banks at 1.8 V or 2.5 V in area-constrained PCB designs. Its 2.2 V minimum input also allows regulation directly from a 3.3 V supply with only 1.1 V headroom overhead.
