The LP2950ACZ-3.3/NOPB is a precision fixed 3.3V low dropout regulator from Texas Instruments, delivering 100mA with a dropout voltage of just 0.6V. The 'A' grade provides tighter output accuracy, making it suitable for analog and reference applications. With a quiescent current of only 120 µA, it excels in battery-powered designs. The TO-92-3 package is robust and widely used in through-hole PCB assemblies.
- Precision Output: Tighter voltage tolerance for critical analog loads.
- Low Power Consumption: 120 µA quiescent current ideal for battery operation.
- Low Dropout: 0.6V at 100mA maximizes usable battery capacity.
- Proven TI Design: Reliable, well-documented, and widely available.
Precision Analog Circuits
The 'A' version offers tighter output voltage tolerance, making it ideal for precision references in data acquisition systems.
Battery Backup Systems
Low dropout ensures stable 3.3V even when the battery voltage drops near the regulation threshold.
Portable Medical Devices
Low quiescent current and reliable operation suit glucose monitors, pulse oximeters, and hearing aids.
Remote Sensor Nodes
Powers wireless sensors with minimal power draw, extending battery life in IoT deployments.
Consumer Electronics
Used in remote controls, calculators, and toys requiring a stable 3.3V rail from 2xAA or 9V batteries.
Automotive Aftermarket
Through-hole package is easy to integrate into custom car electronics like dashcams and GPS trackers.
