Frequently Asked Questions
What is the output voltage and maximum output current of the LP3881ES-1.5?
The LP3881ES-1.5 provides a fixed 1.5V output with a maximum continuous output current of 800mA. The initial output voltage accuracy is ±1%, ensuring reliable operation for voltage-sensitive digital loads.
What package does the LP3881ES-1.5 come in and what are its typical applications?
The LP3881ES-1.5 is available in a SOT-23-5 (5-pin small outline transistor) package, making it ideal for space-constrained designs. Typical applications include powering microcontrollers, DSP cores, FPGAs, wireless modules, and other low-voltage digital ICs in portable and IoT devices.
What is the dropout voltage of the LP3881ES-1.5 and why does it matter?
The LP3881ES-1.5 has a typical dropout voltage of 300mV at 800mA output current. A low dropout voltage means the input supply only needs to be 300mV above the 1.5V output, allowing operation from a 1.8V rail and improving efficiency in battery-powered systems.
Can I buy the LP3881ES-1.5 online and how much does it cost?
Yes, the LP3881ES-1.5 is available for purchase online starting from approximately $3.22 per unit, with stock available for worldwide shipping. Pricing may vary based on order quantity and distributor.
