Frequently Asked Questions
What is the output current and input voltage range of the LP55281TL?
The LP55281TL provides up to 500mA of output current with an input voltage range of 2.5V to 6V, making it suitable for single-cell Li-ion and USB-powered applications.
What applications is the LP55281TL designed for?
It is designed for battery-powered portable devices, IoT sensor nodes, wearables, and any space-constrained embedded system requiring a stable, low-noise LDO regulator with a small package footprint.
What package does the LP55281TL come in?
The LP55281TL is available in a SOT-23-5 (TL) package, which is a very compact 5-pin surface-mount package ideal for space-sensitive PCB layouts.
How do I enable or disable the LP55281TL?
The LP55281TL features a CMOS/TTL-compatible enable pin. Driving the enable pin high activates the regulator, while pulling it low puts the device into shutdown mode, reducing quiescent current to minimize battery drain.
