Frequently Asked Questions - LP2995 TEXAS INSTRUMENTS
What is the LP2995 used for?
The LP2995 is a linear regulator designed for DDR memory termination, providing a low-noise VTT output.
What is the typical output voltage of the LP2995?
The output voltage is adjustable, typically set to half the VDDQ voltage (e.g., 1.25 V for DDR3).
How do I set the output voltage?
The output voltage is set by an external resistor divider connected to the FB pin. Use the formula VOUT = 0.9 V × (1 + R1/R2).
What is the maximum load current?
The LP2995 can deliver up to 1.5 A of continuous output current.
What input voltage range is supported?
The input voltage range is 2.2 V to 5.5 V.
Does the LP2995 require heatsinking?
For high load currents or elevated temperatures, PCB copper area is recommended for heat dissipation.
What capacitors are recommended at input and output?
Typical values: 10 µF ceramic at input and 22 µF ceramic at output.
Is the LP2995 compatible with DDR3 and DDR4?
Yes, the adjustable output voltage makes it suitable for both DDR3 (1.5 V VDDQ) and DDR4 (1.2 V VDDQ).
What protection features does it have?
The LP2995 includes thermal shutdown and current limit protection.
Where can I find the full datasheet?
The official datasheet is available on TI's website (part number: SNVS359).
