Key Features
- Ultra-low 160 mV typical dropout voltage at 300 mA output current extends battery life in portable devices by allowing operation down to near-end-of-charge battery voltages
- Integrated output pull-down resistor and automatic discharge circuit ensure the 2.5 V output rail collapses quickly when enable is deasserted, preventing latch-up in controlled power sequencing systems
- Fixed 2.5 V output in a tiny 5-pin SOT-23 package (R-PDSO-G5) minimizes PCB area for space-constrained IoT modules, wearables, and battery-powered sensor nodes
Applications
MIC5504-2.5YM5-T5 is widely used in battery-powered IoT sensor nodes and wearables to supply a stable 2.5 V rail to microcontrollers, sensors, or RF transceivers from a single-cell Li-ion or two-cell AA battery stack, leveraging its 160 mV dropout to maximize useful operating time. Its enable pin and auto-discharge function make it ideal for power-gated subsystems in portable medical monitors and data loggers, where the 2.5 V peripheral rail must be cleanly switched on and off to minimize quiescent current draw. Industrial handheld instruments also rely on this LDO to regulate precision analog circuitry at 2.5 V from a 3.3 V or 5 V system bus.

Frequently Asked Questions
What is the dropout voltage of MIC5504-2.5YM5-T5 at full load, and how does it affect battery-powered designs?
MIC5504-2.5YM5-T5 has a typical dropout voltage of 160 mV and a maximum of 380 mV at the full 300 mA output current. This means the input supply only needs to be 2.66 V typical (or 2.88 V worst-case) to maintain a regulated 2.5 V output, allowing the design to operate with a Li-ion cell discharged to near its 2.7 V cutoff voltage and extending usable battery runtime by tens of minutes compared to regulators with 500 mV or higher dropout.
How does the automatic output discharge feature of MIC5504-2.5YM5-T5 benefit power sequencing in multi-rail designs?
When the enable pin is pulled low to disable the regulator, the integrated output pull-down resistor actively discharges the 2.5 V output rail to ground within a few milliseconds, depending on the output capacitor value. This prevents the output from floating or discharging slowly through load current alone, which could violate the power-down sequencing requirements of FPGAs, DSPs, or processors that mandate their core and I/O rails fall in a specific order within a defined time window of less than 1 ms.
What input voltage range does MIC5504-2.5YM5-T5 support, and which supply rails can feed it directly?
MIC5504-2.5YM5-T5 accepts an input voltage from 2.5 V to 5.5 V with an absolute maximum of 6 V. This range makes it compatible with 3.3 V and 5 V system buses, single-cell Li-ion battery outputs (2.7 V to 4.2 V), and two-cell NiMH packs (2.4 V to 3.0 V), providing design flexibility across battery chemistries and regulated bus architectures without requiring an intermediate boost stage.
For a compact IoT module design, how does the SOT-23-5 package of MIC5504-2.5YM5-T5 compare to alternatives in board space?
The 5-pin SOT-23 (R-PDSO-G5) package occupies approximately 2.9 mm x 1.6 mm on the PCB, requiring only a small input and output bypass capacitor — typically 1 µF each — for stable operation. This results in a complete 2.5 V regulation solution in under 20 mm² of board area, making it one of the smallest footprints available for a 300 mA LDO, well-suited for module-constrained designs such as Bluetooth SoC carrier boards or sub-GHz sensor PCBs where the regulator must coexist with an antenna ground pour.
