What are the key features of LTC3388EMSE-3#PBF?
- Sub-1 µA quiescent current in standby mode maximizes battery runtime in always-on IoT sensors, wearables, and energy-harvesting systems
- Wide 2.7 V to 20 V input range accommodates single-cell Li-Ion, alkaline battery stacks, and automotive 12 V bus supplies in a single design
- 50 mA output current capability with hysteretic current-mode control delivers fast transient response without external compensation components
- Fixed 3 V output in a small MSOP-8E package minimizes BOM and board area in compact portable and wireless sensor node designs
What is LTC3388EMSE-3#PBF used for?
The LTC3388EMSE-3#PBF is optimized for battery-powered wireless sensor nodes, IoT edge devices, and wearables where its sub-1 µA quiescent current dramatically extends battery life between charges or replacements. Its 2.7 V to 20 V input range also makes it suitable for energy-harvesting power paths and automotive auxiliary rails where input voltage varies widely, yet a stable 3 V output is required for microcontrollers and RF transceivers.

Frequently Asked Questions
How low is the quiescent current of the LTC3388EMSE-3#PBF, and what battery life improvement does that enable?
The LTC3388EMSE-3#PBF draws less than 1 µA quiescent current in light-load standby mode, which translates to dramatically extended battery life in always-on IoT sensor nodes. A 1000 mAh coin cell powering only the regulator's quiescent draw would theoretically last over 100,000 hours, making this part ideal for annual-battery-change or maintenance-free remote sensing deployments.
What is the maximum output current of the LTC3388EMSE-3#PBF, and which load types is it suited for?
The LTC3388EMSE-3#PBF delivers up to 50 mA continuous output current at its fixed 3 V output. This current level is well matched to microcontrollers drawing 5 mA to 30 mA, low-power RF transceivers, BLE SoCs, and environmental sensors, but is insufficient for high-power actuators or motors that require hundreds of milliamps or more.
What input voltage range does the LTC3388EMSE-3#PBF support, and how does that benefit multi-source power designs?
The LTC3388EMSE-3#PBF accepts input voltages from 2.7 V to 20 V, enabling it to operate directly from a single-cell lithium-ion battery (2.8 V to 4.2 V), a 3-cell alkaline stack (4.5 V), a 12 V automotive auxiliary rail, or a supercapacitor-based energy storage module. This wide input range reduces the need for multiple regulator designs when targeting diverse power source scenarios.
How does the hysteretic current-mode control of the LTC3388EMSE-3#PBF simplify PCB design compared to fixed-frequency regulators?
Hysteretic current-mode control in the LTC3388EMSE-3#PBF eliminates the need for an external compensation network, since the control loop is inherently stable across a wide range of output capacitor values and ESR. This simplifies PCB design to just the inductor and output capacitor selection, reducing external component count by 3 to 5 parts compared to conventional fixed-frequency voltage-mode buck regulators that require RC compensation networks.
