Frequently Asked Questions
What input voltage range and output current can the LTC3388IMSE-3#PBF support in a wireless sensor node?
The LTC3388IMSE-3#PBF accepts input voltages from 2.7 V to 20 V and delivers up to 50 mA of output current at 3 V (the fixed output voltage of this variant). Its sub-1 µA quiescent current ensures that a wireless sensor node with a 100 mAh coin cell can maintain the regulator in standby for thousands of hours before battery depletion from quiescent drain alone.
How does the hysteretic current-mode control of LTC3388IMSE-3#PBF simplify the external circuit compared to conventional PWM regulators?
Hysteretic current-mode control in the LTC3388IMSE-3#PBF eliminates the need for external frequency compensation networks required by conventional PWM step-down regulators. The hysteretic architecture is inherently stable with a wide range of output capacitors, reducing BOM count and simplifying PCB layout. The device operates from 2.7 V to 20 V input and delivers 50 mA at 3 V output with minimal external components — typically just an inductor and output capacitor.
For an energy-harvesting design using a small solar panel, what makes LTC3388IMSE-3#PBF suitable compared to standard LDOs?
Unlike linear LDOs that waste excess voltage as heat, the LTC3388IMSE-3#PBF provides switching conversion efficiency that can exceed 90% across its 50 mA output range, critical when harvested power is limited. Its sub-1 µA quiescent current also outperforms most LDOs in ultra-light-load scenarios, and the 2.7 V to 20 V input range accommodates the variable output of a small 6 V solar panel without requiring a secondary regulation stage.
