Key Features
- Ultra-low 150mV typical dropout voltage enabling high-efficiency regulation close to the input rail
- Fixed output in a tiny 5-pin SOT-23 footprint with 2.8V to 5.5V input range for portable and IoT designs
- Low quiescent current and 300mA capability ideal for battery-powered applications requiring long runtime
Applications
The TPS758A01KTTR is well suited for battery-powered wearables, handheld medical devices, and IoT sensor nodes where a stable post-regulated supply is derived from a lithium-ion cell or a 5V rail. Its 150mV typical dropout and 300mA current capability allow efficient linear regulation from a nearly depleted Li-ion battery, maximizing usable runtime while keeping the power-supply circuit within a 5-pin SOT-23 footprint.

Frequently Asked Questions
How low is the dropout voltage of TPS758A01KTTR and why does it matter for battery life?
The TPS758A01KTTR achieves 150mV typical dropout at its rated 300mA output current, with a 300mV worst-case maximum. A low dropout means the device keeps regulating until the input battery voltage falls to just 150mV above the output rail, extending usable battery capacity by tens of minutes in a compact wearable.
Which supply voltages can drive TPS758A01KTTR as its input source?
The regulator accepts input voltages from 2.8V to 5.5V, with an absolute maximum of 6V. This range covers standard 3.3V rails, single-cell lithium-ion batteries (3.0V to 4.2V), and 5V USB power, making it a versatile post-regulator in mixed-rail portable and industrial designs.
For a compact IoT node design, how much board area does the TPS758A01KTTR require?
The 5-pin SOT-23 package (JESD-30 code R-PSSO-G5) occupies a PCB footprint of approximately 1.6mm x 2.9mm, one of the smallest footprints for a 300mA LDO. This makes it suitable for ultra-compact IoT nodes, coin-battery adapters, and wearable modules where every square millimetre of PCB area counts.
Is TPS758A01KTTR lead-free and what JEDEC code does it carry?
Yes, the TPS758A01KTTR carries a JEDEC JESD-609 e3 code, indicating a lead-free finish compliant with RoHS directives. The Pb-free designation ensures compatibility with modern reflow-soldering profiles and international environmental regulations for consumer and industrial electronics markets.
