The LP2950ACZ-3.3G from onsemi is a fixed 3.3V low dropout regulator delivering up to 100mA. With a dropout voltage of just 0.45V at full load and a low quiescent current of 120µA, it is optimized for battery-operated equipment. The TO-92 package offers through-hole mounting for easy prototyping and robust thermal performance.
- Extended Battery Life: 120µA quiescent current minimizes standby power draw.
- High Input Tolerance: Accepts up to 30V input, providing design flexibility.
- Low Dropout: 0.45V dropout at 100mA allows operation close to the output voltage.
- Stable Output: Internal frequency compensation ensures stability with low-ESR capacitors.
