Key Features
- 300 mA output current with 145 mV maximum dropout voltage and ultra-low noise enabling clean power rails for sensitive RF and analog circuits
- High PSRR and 0.033% line regulation / 0.019% load regulation delivering stable 5.5 V output even with noisy switch-mode input supplies
- 5-pin SOT-23 package with low quiescent current suitable for space-constrained, battery-sensitive portable and wearable electronics
Applications
The TPS7A2055PDBVR is designed for post-regulation of noisy switch-mode supplies powering RF transceivers, PLLs, VCOs, and precision ADC reference rails where supply noise directly degrades signal quality. Its ultra-low noise and high PSRR make it ideal for communication modules, medical instrumentation front-ends, and audio signal-chain boards that require a clean 5.5 V regulated output. The compact SOT-23 package and low dropout of 145 mV also suit always-on IoT sensor nodes and wearable health monitors where both board space and quiescent current are constrained.

Frequently Asked Questions
What is the dropout voltage of the TPS7A2055PDBVR, and how does that affect battery-powered designs?
The TPS7A2055PDBVR has a maximum dropout voltage of 145 mV, meaning it maintains regulation with input only 145 mV above the output rail. In battery-powered or post-regulated designs powered from 5.8 V to 6 V input, this low dropout extends usable battery life by allowing operation closer to the output set point, minimizing wasted energy as heat in the 5-pin SOT-23 package.
Which RF or precision analog circuits benefit most from the TPS7A2055PDBVR's noise and PSRR characteristics?
RF transceivers, voltage-controlled oscillators, phase-locked loops, and precision ADC reference circuits are the primary beneficiaries of the TPS7A2055PDBVR's ultra-low output noise and high power-supply rejection ratio. Even when powered from a switching regulator with significant ripple at the 6 V input, the PSRR attenuates that noise to prevent it from appearing on the 300 mA output rail and corrupting sensitive analog measurements or carrier phase.
How precise is the TPS7A2055PDBVR under varying load and line conditions in a production design?
The TPS7A2055PDBVR achieves 0.033% maximum line regulation and 0.019% maximum load regulation, indicating the output voltage shifts by less than 2 mV under typical line and load swings. This tight regulation means precision sensor conditioning circuits and reference voltage chains can use this LDO without adding a separate trimming network, reducing BOM complexity in analog front-end boards.
For a compact IoT module, how does the 5-pin SOT-23 footprint of TPS7A2055PDBVR compare to larger LDO packages?
The SOT-23 (R-PDSO-G5) package occupies roughly 8 mm² of PCB area with a 0.95 mm pin pitch, making it among the smallest footprints available for a 300 mA LDO. Compared to SOT-223 or TO-252 packages used in higher-current regulators, the SOT-23 enables sub-centimeter power-supply sections on constrained IoT radio boards, wireless sensor nodes, and wearable patches where every square millimeter matters.
