Frequently Asked Questions
What is the dropout voltage of the LP2985IM5-3.8?
The LP2985IM5-3.8 has a typical dropout voltage of 280mV and a maximum of 575mV at the full 150mA output current. This low dropout allows the device to regulate a 3.8V output from input voltages as low as 4.8V, making it suitable for single-cell Li-ion battery applications.
What are the typical applications for the LP2985IM5-3.8?
The LP2985IM5-3.8 is designed for noise-sensitive applications such as RF front-end modules, GPS receivers, Bluetooth/Wi-Fi chipsets, and precision ADC/DAC power supplies. Its ultra-low noise characteristic and 3.8V fixed output also make it suitable for powering microcontrollers and sensors in portable consumer electronics and IoT devices.
What package does the LP2985IM5-3.8 come in and what are its pin dimensions?
The LP2985IM5-3.8 uses a 5-pin SOT-23 package (JESD-30 code R-PDSO-G5), a compact surface-mount package with a footprint of approximately 2.9mm × 1.6mm. This small form factor is ideal for space-constrained PCB designs in mobile and wearable devices.
Can the LP2985IM5-3.8 output voltage be adjusted?
No, the LP2985IM5-3.8 has a fixed 3.8V output voltage and is not adjustable. Texas Instruments offers other members of the LP2985 family with different fixed output voltages if an alternative voltage is needed for your design.
