What are the key features of TPS720105DRVT?
- 0.11 V nominal dropout voltage at 350 mA enables regulation from near-discharged Li-ion cells down to 1.55 V input
- Dedicated RF bias pin separates the noise-sensitive bias supply from the main power rail, improving RF circuit PSRR
- 350 mA output current supports RF power amplifiers, VCOs, and transceivers in wireless IoT and cellular modules
- 6-pin SOT-563 (JESD-30 S-PDSO-N6) package minimizes PCB footprint for space-constrained RF front-end designs
What is TPS720105DRVT used for?
TPS720105DRVT is designed to supply RF power amplifiers, voltage-controlled oscillators, and radio transceivers in cellular, Bluetooth, and Wi-Fi modules where a clean, low-noise LDO rail is critical for maintaining RF performance metrics. Its dedicated bias pin allows the RF bias circuit to be powered independently with low ripple, improving power supply rejection ratio and reducing phase noise in sensitive oscillator circuits. The ultra-low 0.11 V dropout enables continuous regulation from single-cell Li-ion batteries even as the cell voltage drops toward end-of-discharge at 3.0 V.

Frequently Asked Questions
What is the dropout voltage of TPS720105DRVT, and how low can the input voltage drop before regulation is lost at 350 mA?
TPS720105DRVT has a nominal dropout voltage of 0.11 V and a maximum of 0.2 V at 350 mA load. For a 0.5 V output, this means regulation is maintained down to approximately 0.7 V input in typical conditions, but within the specified 1.55 V to 4.5 V input range, making it suitable for Li-ion powered RF modules operating near end-of-discharge.
How does the RF bias pin on TPS720105DRVT improve performance in wireless transceiver applications compared to a standard LDO?
The dedicated RF bias pin allows the noise-sensitive bias supply for RF blocks such as VCOs and LNAs to be separated from the main output rail, reducing conducted noise coupling between digital switching activity and the RF analog supply. This configuration improves power supply rejection ratio (PSRR) at RF frequencies, which directly lowers phase noise and spurious emission levels in wireless designs operating at 2.4 GHz or 5 GHz.
How does TPS720105DRVT's 6-pin SOT-563 package compare to a standard SOT-23-5 in a compact RF PCB layout?
The 6-pin SOT-563 package used by TPS720105DRVT has a body size of approximately 1.6 mm × 1.2 mm, which is significantly smaller than the SOT-23-5 body at 2.9 mm × 1.6 mm. For RF module designs with sub-1 cm² PCB budgets, this size difference allows more aggressive component placement and shorter RF supply bypass traces, which reduces parasitic inductance and improves high-frequency PSRR.
