Frequently Asked Questions
What is the output voltage range of LP2997?
The LP2997 output is adjustable from 1.2V to 5V using an external resistor divider. The internal reference voltage is 1.2V. For a 3.3V output, use R1=35.7kΩ and R2=20kΩ. The output voltage accuracy is ±2% over temperature.
What is the maximum input voltage for LP2997?
The LP2997 accepts input voltages from 2.2V to 16V, providing wide input range for various power sources including USB, automotive, and multi-cell battery applications. Always maintain at least 350mV headroom above the desired output voltage.
Does LP2997 support ceramic output capacitors?
Yes, the LP2997 is specifically designed to be stable with low-ESR ceramic output capacitors. A minimum 10µF ceramic capacitor is recommended. This eliminates the need for bulky tantalum capacitors and simplifies BOM.
What protection features does LP2997 have?
The LP2997 includes thermal shutdown protection, current limiting (foldback type), and an enable pin for controlled power-up/down. The enable pin is logic-compatible (VIH=1.2V) and can be driven directly by GPIO pins.
