Applications
The TPS62A01DRLR is optimized for always-on IoT sensor nodes, wearable devices, and Bluetooth/Wi-Fi modules powered from single-cell Li-ion batteries or USB supplies ranging from 2.5 V to 5.5 V, where minimizing quiescent current and PCB area are the primary design constraints. Its PSM light-load operation significantly extends battery life in duty-cycled wireless applications, while the compact SOT-563 package allows integration alongside sub-GHz radio ICs and MEMS sensors on densely populated flex or rigid PCBs.

Frequently Asked Questions
How does TPS62A01DRLR PSM operation extend battery life compared to fixed-PWM regulators in duty-cycled IoT designs?
In PSM mode, TPS62A01DRLR reduces switching frequency at light loads — typically below 10 mA output current — cutting switching losses and dropping quiescent current to the µA range versus several hundred µA for fixed-frequency PWM operation. For an IoT node sleeping 99% of the time drawing only 100 µA average from a 3.7 V Li-ion cell, this can extend 500 mAh battery runtime from weeks to months compared to a conventional always-switching PWM regulator.
Can TPS62A01DRLR supply a 3.3 V output from a USB 5 V input for a microcontroller and what output current is available?
Yes, with a 5 V USB input within the 2.5 V to 5.5 V operating range, TPS62A01DRLR efficiently converts to a regulated 3.3 V output. The specific maximum output current is determined by the configured feedback resistors and inductor selection, typically supporting up to several hundred mA continuous at this input/output combination. Designers should consult the TPS62A01 datasheet for the exact current rating and recommended 2.2 µH to 4.7 µH inductor values appropriate for the switching frequency and load.
What PCB footprint does the SOT-563 package of TPS62A01DRLR require compared to a standard SOT-23?
The 6-lead SOT-563 package of TPS62A01DRLR measures approximately 1.6 mm x 1.2 mm, occupying roughly 1.9 mm² of board area, compared to the standard 3-lead SOT-23 which spans about 2.9 mm x 1.3 mm or roughly 3.8 mm². This nearly 50% reduction in footprint makes TPS62A01DRLR well-suited for wearables, hearing aids, and miniaturized IoT tags where board real estate is at a premium alongside RF and sensor components.
Is TPS62A01DRLR a suitable replacement for a discrete LDO in a 3.7 V to 1.8 V conversion where heat dissipation is a concern?
TPS62A01DRLR is an excellent switching-regulator alternative to an LDO for 3.7 V to 1.8 V conversion. An LDO in this scenario dissipates (3.7 V - 1.8 V) × I_load = 1.9 V × load current as heat, reaching 190 mW at 100 mA — requiring thermal management in a compact design. TPS62A01DRLR in PWM mode achieves over 80% efficiency at the same operating point, reducing heat dissipation to under 40 mW, eliminating heatsinking and extending PCB and battery life simultaneously.
