Frequently Asked Questions
What is the maximum output current of the LP38500SD-ADJ/NOPB?
The LP38500SD-ADJ/NOPB delivers up to 1.5A continuous output current with a very low 130mV dropout voltage at full load. This high current capability makes it suitable for powering DDR memory, FPGAs, and processor core rails.
How is the output voltage adjusted on the LP38500SD-ADJ/NOPB?
The output voltage is set using an external resistor divider from the output to the ADJ pin and ground. The adjustable range covers 0.5V to 3.3V, with the feedback reference voltage of 0.5V determining the minimum achievable output.
What is the dropout voltage of the LP38500SD-ADJ/NOPB?
At 1.5A full load the dropout voltage is only 130mV typical, meaning a 3.3V output requires just 3.43V input. This ultra-low dropout maximizes efficiency and extends operation from tightly regulated 3.3V or 5V supply rails.
What package does the LP38500SD-ADJ/NOPB use?
The device is packaged in a 5-pin TO-263 (D2PAK) with a large exposed thermal pad for excellent heat dissipation. The TO-263 package can dissipate over 2W with proper PCB copper area, supporting sustained 1.5A operation.
What are typical applications for the LP38500SD-ADJ/NOPB?
Common applications include DDR SDRAM termination voltage regulators, FPGA and DSP core supplies, networking equipment power rails, and any point-of-load application requiring clean, fast-response 1.5A regulation from a 5V or 3.3V bus.
