Frequently Asked Questions
What is the dropout voltage of the LP3983ITL-2.5/NOPB?
The LP3983ITL-2.5/NOPB has a typical dropout voltage of 178mV at 150mA output current. This ultra-low dropout characteristic allows it to regulate 2.5V output from input voltages as low as 2.678V, making it excellent for single-cell Li-Ion battery applications near end-of-discharge.
What applications is the LP3983ITL-2.5/NOPB designed for?
The LP3983ITL-2.5/NOPB is designed for noise-sensitive portable applications including RF transceivers, GPS modules, Bluetooth chips, and precision ADC/DAC power rails. Its 30uV RMS noise and 75dB PSRR make it ideal wherever a clean, stable 2.5V supply is needed from a 3.3V or Li-Ion battery rail.
Is the LP3983ITL-2.5/NOPB RoHS compliant and lead-free?
Yes. The /NOPB suffix explicitly indicates this part is lead-free and RoHS compliant. It meets EU RoHS Directive 2011/65/EU requirements and is suitable for all green manufacturing processes.
What are suitable alternatives to the LP3983ITL-2.5/NOPB?
Compatible alternatives include the TLV70025DCKR (Texas Instruments, SOT-23-5, 200mA), MIC5365-2.5YC5 (Microchip, SOT-23-5, 150mA), and XC6206P252MR (Torex, SOT-23-3, 200mA). The TLV70025 is the closest pin-compatible upgrade with slightly higher output current.
How does the LP3983ITL-2.5/NOPB SOT-23-5 footprint simplify PCB layout?
The SOT-23-5 package measures only 1.6mm x 2.9mm with a 0.95mm pitch, requiring just two small ceramic capacitors (1uF input, 1uF output) for a complete regulator circuit. Its tiny footprint and minimal external component count make PCB layout straightforward even in dense designs such as wearables and IoT modules.
