Frequently Asked Questions
What is the dropout voltage of the LP38851T-ADJ?
The LP38851T-ADJ features a nominal dropout voltage of 0.115V and a maximum dropout voltage of 0.2V, making it an ultralow-dropout (ULDO) regulator. This low dropout allows the device to maintain regulation even when the input voltage is very close to the output voltage, maximizing efficiency in battery-powered and low-headroom applications.
What applications is the LP38851T-ADJ suitable for?
The LP38851T-ADJ is well-suited for portable consumer electronics, telecommunications equipment, industrial power supplies, and any application requiring a stable adjustable DC voltage rail. Its adjustable output and ultralow dropout voltage make it particularly effective for powering microcontrollers, DSPs, FPGAs, and other logic ICs that require precise, low-noise power supplies.
How does the adjustable output work on the LP38851T-ADJ?
The LP38851T-ADJ supports an adjustable output voltage configuration, allowing designers to set the desired output voltage using external resistors connected to the ADJ pin. This provides design flexibility to target a wide range of output voltages from a single component, reducing inventory complexity and enabling customization for different load requirements.
What package does the LP38851T-ADJ come in, and where can I buy it?
The LP38851T-ADJ is available in the R-XZFM-T7 package (7-lead thin SOT-223 style). It is manufactured by Texas Instruments and is available worldwide starting from approximately $1.15 per unit.
