Frequently Asked Questions

What is the dropout voltage of the LP5907MFX-3.1/NOPB and how does it benefit single-cell Li-Ion battery designs?

The LP5907MFX-3.1/NOPB has a typical dropout voltage of only 0.12 V and a maximum of 0.25 V at 250 mA output current. With a minimum input voltage of 2.2 V and a fixed 3.1 V output, the device can regulate from a Li-Ion cell even as the battery discharges toward its end-of-life voltage, extending usable battery runtime in IoT nodes and wearable devices.

Why is the LP5907MFX-3.1/NOPB preferred for powering RF and precision analog circuits compared to standard LDOs?

The LP5907MFX-3.1/NOPB is characterized as an ultra-low-noise LDO, meaning its output noise spectral density is significantly lower than standard LDO regulators. RF transceivers, PLL synthesizers, and precision ADCs are highly sensitive to power supply noise, and low output noise from the 3.1 V rail directly improves phase noise, spurious-free dynamic range, and SNR performance in these circuits.

What input voltage range does the LP5907MFX-3.1/NOPB accept and which power sources does that cover?

The LP5907MFX-3.1/NOPB accepts input voltages from 2.2 V to 5.5 V, with an absolute maximum rating of 6 V. This range covers single-cell Li-Ion batteries (3.0 V to 4.2 V), USB 5 V rails, and 3.3 V system buses, making the regulator versatile across portable, industrial IoT, and USB-powered device designs requiring a stable 3.1 V output.

How long is the LP5907MFX-3.1/NOPB expected to remain in production and what does that mean for procurement?

Texas Instruments rates the LP5907MFX-3.1/NOPB with a YTEOL (Years To End Of Life) of 15 years, one of the longest lifecycles available for an LDO in the SOT-23 5-pin package. Procurement teams can confidently design this part into long-lifecycle medical, industrial, and telecommunications products without near-term end-of-life risk, reducing redesign costs over a 10 to 15 year production horizon.
