Key Features
- Ultra-low 155 mV typical dropout voltage enables regulation from a 4 V input supply down to near-rail outputs
- Dual independent output channels provide two regulated rails from a single 4–5.5 V supply for multi-rail SoC designs
- 6-pad UDFN no-lead package occupies minimal PCB area for wearables and IoT modules
- RoHS e4 compliant with 5.5 V absolute maximum input protects against USB overvoltage transients
Applications
The MIC5393-PPYMT-T5 is designed for dual-rail power management in compact IoT modules, wearable devices, and USB-powered accessories requiring two LDO outputs from a 4–5.5 V supply. Its ultra-low dropout of 155 mV typical makes it ideal for supplying 3.3 V and 1.8 V rails from a single-cell Li-ion battery near end-of-discharge. The UDFN-6 package allows integration into space-constrained layouts alongside Bluetooth SoCs, microcontrollers, and sensor ICs.

Frequently Asked Questions
How low a dropout voltage does the MIC5393-PPYMT-T5 achieve, and why does that matter for Li-ion battery operation?
The MIC5393-PPYMT-T5 has a typical dropout voltage of only 155 mV (maximum 310 mV). A single-cell Li-ion battery discharges from 4.2 V down to 3.0 V. With a 3.3 V output rail, the LDO requires at least 3.3 V + 0.31 V = 3.61 V input to maintain regulation, enabling continued operation down to approximately 3.6 V battery voltage rather than the 4 V+ cutoff required by higher-dropout alternatives.
What is the input voltage range of the MIC5393-PPYMT-T5 and which power sources are compatible?
The MIC5393-PPYMT-T5 accepts inputs from 4 V minimum to 5.5 V maximum. This range is directly compatible with USB 5 V bus (4.75–5.25 V), USB-C VBUS, and single-cell Li-ion batteries above 4 V (freshly charged). The 5.5 V maximum also tolerates typical USB adapter overshoot without requiring additional transient protection components.
How does the UDFN-6 package of the MIC5393-PPYMT-T5 compare to SOT-23 for board space on a wearable design?
The UDFN-6 (ultra-thin DFN, 6 pads) has a typical body size of 1.6 mm x 1.6 mm with 0.5 mm pad pitch, compared to SOT-23-5 at 3 mm x 1.75 mm. This roughly 3x reduction in footprint area is significant for wearables where PCB real estate is measured in square millimeters and dual LDO outputs from a single 6-pad package save the space of a second discrete regulator.
Can the MIC5393-PPYMT-T5 supply both a 3.3 V microcontroller rail and a 1.8 V sensor rail simultaneously?
Yes. The dual output design provides 2 independent regulated channels. As long as the combined output current for both rails stays within the device's rated load capability (typically 150–300 mA per channel depending on thermal conditions in the UDFN-6 package) and the input is within 4–5.5 V, the device maintains both 3.3 V and 1.8 V simultaneously from a single USB or Li-ion source.
