What are the key features of LP5907MFX-1.5/NOPB?
- Ultra-low-noise output for sensitive RF and ADC supply rails in wireless and precision measurement designs
- 250 mA output current with only 120 mV typical dropout voltage enabling high-efficiency operation
- Low quiescent current extending battery life in IoT, wearable, and energy-harvesting applications
- Compact 5-pin SOT-23 package operating from 2.2 V to 5.5 V input for broad compatibility
What is LP5907MFX-1.5/NOPB used for?
LP5907MFX-1.5/NOPB is designed to power noise-sensitive loads such as RF transceivers, ADCs, and PLLs in wireless IoT modules and precision instrumentation where supply noise directly degrades signal quality. Its 1.5 V fixed output and 250 mA current capacity suit Bluetooth Low Energy SoCs, MEMS microphones, and optical sensors operating from single-cell Li-ion or USB-C power paths. The ultralow noise floor and low dropout voltage also make it suitable for wearable health monitors and portable medical diagnostic devices requiring stable, clean supply rails.

Frequently Asked Questions
What is the typical dropout voltage of LP5907MFX-1.5/NOPB, and how does it affect efficiency near the 1.5 V output?
LP5907MFX-1.5/NOPB has a typical dropout voltage of 120 mV and a maximum of 250 mV at full 250 mA load. This means the input supply only needs to be 1.62 V or higher to maintain the regulated 1.5 V output, enabling highly efficient operation from a nearly-depleted Li-ion cell at 2.2 V minimum input.
Which noise-sensitive circuit blocks benefit most from LP5907MFX-1.5/NOPB's ultra-low-noise output?
LP5907MFX-1.5/NOPB is especially beneficial for RF LNAs, 12-bit to 16-bit ADCs, PLLs, and MEMS microphones where supply noise couples directly into the signal path. Its ultra-low output noise, typically in the range of a few µV RMS across 10 Hz to 100 kHz, prevents spur injection and SNR degradation that switching regulators would introduce.
Can LP5907MFX-1.5/NOPB power a Bluetooth LE SoC from a 3.3 V USB-derived supply rail?
Yes, LP5907MFX-1.5/NOPB accepts an input from 2.2 V to 5.5 V, so a 3.3 V USB-derived rail is well within its range. It delivers up to 250 mA at a fixed 1.5 V output, sufficient for most BLE SoC active-transmit current peaks in the 100 mA to 200 mA range, while its low noise keeps the RF front-end sensitivity uncompromised.
How does the 5-pin SOT-23 package of LP5907MFX-1.5/NOPB simplify placement on a compact IoT sensor PCB?
The 5-pin SOT-23 package of LP5907MFX-1.5/NOPB measures approximately 2.9 mm × 1.6 mm, occupying under 5 mm² of board area. This tiny footprint, combined with a simple 2-capacitor external circuit, allows the LDO to be placed directly adjacent to sensitive analog or RF loads on densely packed IoT sensor PCBs with layer counts as low as 2.
