Frequently Asked Questions
What is the maximum input voltage for LM3480?
The LM3480 accepts input voltages up to 30V, making it suitable for 5V, 12V, and 24V bus regulation down to 3.3V. The wide input range provides excellent flexibility across various power architectures without risking the regulator.
What is the dropout voltage of LM3480?
The LM3480 has a typical dropout voltage of 1.2V at 100mA full load. This means minimum input should be 4.5V for reliable 3.3V output. At lighter loads, dropout is lower, around 400mV at 10mA.
Why choose LM3480 over other 3.3V LDOs?
LM3480 is chosen for its 30V input tolerance (most LDOs max at 5.5V), tiny SOT-23-3 package (only 3 pins, smallest possible), and robust protection. It's ideal when regulating from high-voltage rails where other LDOs cannot operate.
What output capacitor does LM3480 require?
LM3480 requires a minimum 1µF output capacitor. Ceramic capacitors work well due to their low ESR. For best transient response, use 4.7µF or larger. A 0.1µF input bypass capacitor is recommended close to the input pin.
