Product details
Overview
LTC3104EMSE#PBF from Analog Devices is an ultralow-quiescent-current synchronous step-down DC/DC converter with an integrated 10mA LDO regulator. The device is designed for always-on and battery-powered systems that need efficient 300mA buck conversion from inputs up to 15V while maintaining very low standby current.
As part of the LTC3104 product family, LTC3104EMSE#PBF combines 2.6uA quiescent current, synchronous rectification, 300mA output capability, 1.2MHz fixed-frequency PWM operation, Burst Mode or forced continuous mode, programmable RUN threshold, power-good status, and a 10mA adjustable LDO. For engineers reviewing the LTC3104EMSE#PBF datasheet, LTC3104EMSE#PBF pinout, LTC3104EMSE#PBF application, or LTC3104EMSE#PBF equivalent, this device is widely used in automotive always-on rails, industrial sensors, battery-powered instruments, standby supplies, low-power microcontroller systems, and compact embedded power architectures.
Technical Context
In low-power embedded systems, LTC3104EMSE#PBF operates as a synchronous buck regulator that steps a 2.5V to 15V input down to a regulated output between 0.6V and 13.8V. Synchronous rectification improves efficiency, especially at moderate loads compared with diode-based converters.
The 2.6uA quiescent current makes the device suitable for standby rails and always-on loads. Designers can use automatic Burst Mode operation for very low power consumption or forced continuous operation when predictable switching behavior and lower ripple are more important.
LTC3104EMSE#PBF is commonly used in systems that need a small 300mA buck rail, a 10mA auxiliary LDO, programmable input undervoltage threshold, and power-good reporting from a compact thermally enhanced MSOP package.

Equivalent & Alternatives
When evaluating a LTC3104EMSE#PBF equivalent, engineers should compare input range, quiescent current, 300mA output capability, LDO output, Burst Mode behavior, switching frequency, package, and power-good function.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC3104EDE#PBF | Same LTC3104 family in a thermally enhanced DFN package option. | Used when the same low-IQ buck-plus-LDO function is required in a different footprint. | Compare package, thermal path, assembly process, and availability. |

Compared with LTC3104EDE#PBF, LTC3104EMSE#PBF is selected when the MSOP package is required. LTC3104EMSE#PBF vs TPS62177 selection depends on whether the design needs the integrated 10mA LDO, package compatibility, quiescent current, and output-current requirements.
Quality
LTC3104EMSE#PBF should be sourced as original Analog Devices components through traceable supply channels. Quality checks may include MSOP package inspection, top-mark validation, solderability testing, and buck/LDO output verification.
Production validation should include low-IQ current, Burst Mode behavior, forced continuous operation, power-good timing, output accuracy, thermal behavior, and layout-sensitive switching ripple.
