Frequently Asked Questions
What are the output voltages and current ratings of the LP3996SD-3333?
The LP3996SD-3333 provides two fixed 3.3V outputs: the primary LDO1 delivers up to 300mA and the secondary LDO2 delivers up to 150mA. Both outputs are fixed at 3.3V and include internal current limiting for protection.
What is the input voltage range for the LP3996SD-3333?
The LP3996SD-3333 accepts an input voltage ranging from 2V minimum to 6V maximum, with an absolute maximum of 6.5V. This wide range makes it compatible with single-cell Li-ion batteries, two-cell alkaline packs, and USB 5V power sources.
Does the LP3996SD-3333 include a power-on reset function?
Yes, the LP3996SD-3333 integrates a power-on reset (POR) circuit that asserts a reset signal during startup until both outputs are within regulation. This simplifies microcontroller and FPGA reset management without requiring external supervisory ICs.
What package does the LP3996SD-3333 use and what are its dimensions?
The LP3996SD-3333 is packaged in a 10-pin Small Outline No-Lead (SON/WSON) package. This compact, lead-free package offers excellent thermal performance and is designed for PCB layouts where space is at a premium.
What applications is the LP3996SD-3333 best suited for?
The LP3996SD-3333 is ideal for portable electronics, wireless modules, IoT nodes, and wearables that need dual 3.3V rails. Its low dropout voltage (0.21V typical) and integrated POR make it a versatile choice for battery-powered microcontroller systems requiring reliable dual-supply regulation.
