Frequently Asked Questions
What is the LP3874EMP-ADJ/NOPB?
The LP3874EMP-ADJ/NOPB is a 1A adjustable LDO (Low Dropout) linear voltage regulator from Texas Instruments. It supports an adjustable output voltage range of 1.21V to 6.5V set via two external resistors, with an input voltage range of 2.5V to 8.5V. The device is housed in a compact SOT-23-5 package and is suitable for space-constrained portable and industrial designs.
What package is the LP3874EMP-ADJ/NOPB and how many pins does it have?
The LP3874EMP-ADJ/NOPB comes in a SOT-23-5 (TSOT-23) package with 5 pins. This small surface-mount package makes it ideal for applications with limited PCB area, such as wearables, IoT nodes, and handheld instruments.
What are the alternatives to LP3874EMP-ADJ/NOPB?
Compatible alternatives include the LP2985-ADJ (lower quiescent current LDO in SOT-23) and the TPS73xx series adjustable LDOs. For higher current needs, consider the LM317. All alternatives require validating the output voltage range and dropout voltage against your system requirements.
Is the LP3874EMP-ADJ/NOPB RoHS compliant?
Yes, the LP3874EMP-ADJ/NOPB is fully RoHS compliant and lead-free (Pb-free). The NOPB suffix indicates No Lead termination, confirming compliance with RoHS Directive 2011/65/EU and its amendments.
How do I set the output voltage of the LP3874EMP-ADJ/NOPB?
The output voltage is set using two external resistors connected to the ADJ pin. The formula is: Vout = Vref x (1 + R1/R2), where Vref = 1.21V. By selecting appropriate R1 and R2 values, you can adjust the output anywhere from 1.21V to 6.5V. Refer to the LP3874 datasheet for recommended resistor values and application circuit.
