The TPS76125SF5 is a fixed 2.5V low dropout linear regulator from TAEJIN, delivering up to 150mA in a compact SOT-23-5L package. With a low dropout voltage of 0.35V at full load and a quiescent current of only 180µA, it is optimized for battery-powered and portable applications. The high 75dB PSRR at 100Hz ensures clean, stable output even with noisy input supplies, making it suitable for sensitive analog and RF circuits.
- Extended Battery Life: Ultra-low 180µA quiescent current minimizes standby power draw, ideal for always-on IoT devices.
- Clean Power Delivery: 75dB PSRR at 100Hz effectively filters mains ripple, ensuring stable voltage for precision analog circuits.
- Compact Footprint: SOT-23-5L package saves PCB space, enabling miniaturized wearable and portable designs.
- Low Dropout: 0.35V dropout at 150mA allows operation from nearly depleted batteries, maximizing usable energy.
Battery-Powered IoT Sensors
The 2.5V fixed output and 150mA capability are ideal for powering low-power microcontrollers and sensors in IoT nodes. The low 180µA quiescent current extends battery life during standby.
Portable Medical Devices
With 75dB PSRR at 100Hz, this LDO effectively rejects mains-frequency ripple, ensuring clean power for sensitive analog front-ends in glucose monitors or pulse oximeters.
Wearable Electronics
The SOT-23-5L package and low dropout of 0.35V allow operation from a single Li-ion cell (3.0-4.2V) down to 2.85V, maximizing usable battery capacity in smartwatches and fitness bands.
Reference Voltage for ADCs
Stable 2.5V output with high PSRR makes it suitable as a reference supply for 12-bit ADCs in industrial data acquisition, reducing conversion errors from power supply noise.
Automotive Interior Lighting
For LED driver control logic requiring 2.5V, this regulator provides a clean, stable rail from the 5V automotive bus, with dropout margin sufficient for cold-crank conditions.
RF Transceiver Power
The 75dB PSRR at 100Hz helps suppress noise from switching regulators in RF modules, improving signal integrity for 2.4GHz transceivers in smart home devices.
