Frequently Asked Questions
What are the output voltages of the LP2966IMM-2518?
The LP2966IMM-2518 provides two fixed regulated outputs: 2.5V and 1.8V. Each output supports up to 150mA of continuous load current, making it suitable for dual-rail digital systems such as microcontrollers paired with low-voltage I/O or memory interfaces.
What is the minimum input voltage required for the LP2966IMM-2518?
The LP2966IMM-2518 requires a minimum input voltage of 2.7V, with a maximum of 7V absolute. The typical dropout voltage is only 135mV (270mV max), so it can regulate 2.5V output from input voltages as low as approximately 2.8V, ideal for single-cell Li-ion battery applications.
What package does the LP2966IMM-2518 come in?
The LP2966IMM-2518 is housed in an MSOP-8 (Mini Small Outline Package, 8-pin) package, designated by the 'IMM' suffix. This compact SMD package is suited for high-density PCB layouts where board space is at a premium, such as portable devices and wearable electronics.
Can the LP2966IMM-2518 replace a single-output LDO in a design?
Yes. The LP2966IMM-2518 integrates two independent LDO regulators in one package, potentially replacing two separate single-output LDOs. This reduces BOM count, saves PCB area, and simplifies layout. Ensure both output voltage specifications (2.5V and 1.8V) match your system requirements before substitution.
