Frequently Asked Questions
What is the output voltage and maximum output current of the LP3872ES-1.8?
The LP3872ES-1.8 provides a fixed 1.8V output voltage with a maximum output current of 1.5A, making it suitable for powering low-voltage digital ICs such as DSPs, FPGAs, and microcontrollers in embedded systems.
What is the dropout voltage of the LP3872ES-1.8 and why does it matter?
The LP3872ES-1.8 has a typical dropout voltage of 0.7V and a maximum of 0.55V at rated current. A low dropout voltage means the regulator can maintain regulation with an input voltage only slightly above the output, improving efficiency in battery-powered and low-supply applications.
What is the input voltage range for the LP3872ES-1.8?
The LP3872ES-1.8 accepts an input voltage between 2.35V (minimum) and 7V (maximum), with an absolute maximum rating of 7.5V. This wide input range makes it compatible with single-cell Li-ion batteries and various regulated supply rails.
What package does the LP3872ES-1.8 come in and what does the 'ES' suffix indicate?
The LP3872ES-1.8 is housed in a 5-pin SOT-23 package (JESD-30 code: R-PSSO-G5). The 'ES' suffix typically denotes the SOT-23 package variant in Texas Instruments' LP3872 series, offering a compact, surface-mount footprint for space-constrained PCB designs.
What are typical applications for the LP3872ES-1.8?
Typical applications include powering 1.8V I/O interfaces, memory chips, wireless modules, IoT sensors, and portable consumer electronics. Its stable 1.8V output and low dropout make it an excellent choice for any design requiring a regulated low-voltage rail from a higher supply.
