The LP2950-30LPRE3 from Texas Instruments is a fixed 3.0V LDO regulator delivering 100mA. With an ultra-low quiescent current of 120µA and dropout of 0.6V, it is optimized for battery-powered applications. The TO-92-3 package is easy to integrate in through-hole designs, while the wide input range up to 30V adds versatility.
- Ultra-Low Quiescent Current: 120µA extends battery life in always-on devices, ideal for IoT and wearables.
- Wide Input Range: Accepts up to 30V, allowing use in industrial and automotive systems without pre-regulation.
- Low Dropout: 0.6V at 100mA ensures regulation even with nearly depleted batteries.
- Simple TO-92 Package: Through-hole design simplifies prototyping and manual assembly.
Battery-Powered IoT Sensors
The 120µA quiescent current and 0.6V dropout allow operation from a single Li-ion cell, maximizing battery life in wireless sensors.
Portable Medical Monitors
With 100mA output, it powers low-power microcontrollers and displays in glucose meters and pulse oximeters, ensuring stable 3V logic.
Wearable Fitness Trackers
The TO-92 package is compact and reliable for wearable PCBs, providing 3V from a coin cell or small LiPo battery.
Remote Keyless Entry Systems
In automotive fobs, the low quiescent current extends battery life while delivering clean 3V to the RF transmitter and MCU.
Smart Meters
For utility meters, the wide 30V input range allows direct connection to 24V industrial supplies, stepping down to 3V for electronics.
Analog Sensor Conditioning
The low dropout ensures stable 3V for op-amps and ADCs in portable instrumentation, even as batteries discharge.
