Key Features
- 300 mA output current with only 0.22 V typical dropout voltage at full load for efficient low-headroom power rails
- Fixed 2.43 V output with input range 4.8 V to 5.5 V, tolerating up to 6 V absolute maximum for robust USB-powered designs
- Compact 6-pin small-outline no-lead package enabling minimal board footprint in space-constrained portable electronics
Applications
TLV70243DSET is designed for powering microcontrollers, sensors, and RF modules in portable and battery-operated devices where headroom between input and output is limited. Its low 0.22 V dropout allows operation from a single-cell Li-ion battery or USB 5 V rail while maintaining a clean 2.43 V supply. The compact SOT-23 footprint suits wearables, IoT nodes, and handheld instruments where board space is at a premium.

Frequently Asked Questions
What dropout voltage does TLV70243DSET guarantee at 300 mA output current?
TLV70243DSET has a typical dropout voltage of 0.22 V and a maximum of 0.375 V at its full 300 mA output current. This low dropout allows the regulator to maintain a stable 2.43 V output even when the supply from a USB 5 V rail dips close to the regulated voltage.
Can TLV70243DSET operate directly from a USB 5 V supply in a portable sensor node?
Yes. TLV70243DSET accepts an input voltage from 4.8 V to 5.5 V with an absolute maximum of 6 V, fitting directly on a USB 5 V bus. It delivers up to 300 mA at a fixed 2.43 V output, making it suitable for powering microcontrollers and sensors in battery-backed or USB-powered IoT sensor nodes.
How does the 6-pin no-lead package of TLV70243DSET help in compact PCB designs?
The S-PDSO-N6 (6-pin small-outline no-lead) package of TLV70243DSET occupies a very small PCB footprint compared to standard SOT-23 or SOIC packages. This allows designers to place the LDO close to the load device, reducing trace resistance and noise pickup in wearables, hearing aids, and miniaturized industrial sensors.
When should a designer choose TLV70243DSET over a switching regulator for 2.43 V generation?
TLV70243DSET is preferable when the load current stays below 300 mA and the input-to-output voltage difference is small, such as stepping from 5 V to 2.43 V. The LDO produces no switching noise, which is important for noise-sensitive analog or RF circuits. A switching regulator would be more efficient for higher currents or larger voltage differentials exceeding 1 V.
