Product details
Overview
MIC5310-PPYMLTR from Microchip Technology is a 300mA low-dropout linear regulator with fixed 3.3V output, ±2% accuracy, and 60µA quiescent current, designed for powering microcontrollers and sensors in battery-operated IoT edge nodes.
For engineers reviewing the MIC5310-PPYMLTR datasheet, MIC5310-PPYMLTR pinout, MIC5310-PPYMLTR application, or MIC5310-PPYMLTR equivalent, key selection factors include dropout voltage at 300mA load, thermal shutdown behavior, reverse-current protection, and stable operation with 1µF ceramic output capacitor.
Technical Context
The MIC5310-PPYMLTR employs a PMOS pass transistor architecture enabling ultra-low dropout (170mV at 300mA), eliminating body-diode conduction during shutdown. It integrates internal soft-start to limit inrush current and features thermal foldback protection that reduces output current above 150°C junction temperature.
Designed for space-constrained applications, it operates across -40°C to +125°C ambient and maintains regulation with input voltages as low as 2.3V - supporting single-cell Li-ion and two-cell alkaline supply rails without brownout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% - ensures reliable logic-level compatibility with 3.3V microcontrollers and peripherals. |
| Max Output Current | 300mA - sufficient to power ARM Cortex-M0+ MCUs with active RF transceivers and analog sensors simultaneously. |
| Dropout Voltage | 170mV at 300mA - enables stable regulation down to 3.47V input, extending usable battery life in single-cell Li-ion systems. |
| Quiescent Current | 60µA - minimizes standby power loss in always-on sensor nodes with multi-year battery requirements. |
| PSRR | 65dB at 1kHz - suppresses switching noise from adjacent DC-DC converters feeding mixed-signal sensor signal chains. |
| Output Capacitor | 1µF ceramic - allows use of small, low-ESR MLCCs; no tantalum or electrolytic required for stability. |
Pinout & Package
Package: 4-pin 1.2mm × 1.6mm µDFN with exposed thermal pad (EP). RoHS-compliant, halogen-free, moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 2.3V–6.0V unregulated input; connects directly to battery or upstream DC-DC output. |
| GND | Ground reference | Common return path for input, output, and internal bias; must be connected to thermal pad for thermal performance. |
| EN | Enable control | Active-high logic input; pulls device into ultra-low IQ shutdown mode (<1µA) when driven low. |
| OUT | Regulated output | Delivers stable 3.3V to load; requires ≥1µF ceramic capacitor placed within 2mm of OUT and GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Transistor | Enables true zero-current reverse leakage and eliminates body-diode forward conduction during shutdown. |
| Internal Soft-Start | Controls output ramp rate to prevent inrush current spikes that could destabilize shared input rails. |
| Thermal Foldback Protection | Reduces output current linearly above 150°C junction temperature to sustain safe operation under sustained overload. |
| Stable with 1µF Ceramic Cap | Eliminates need for larger, higher-ESR capacitors - reduces board area and cost while improving transient response. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/TT | 250mA max output, 175mV dropout at 250mA, 1.8µA quiescent current in shutdown | Lacks enable pin; fixed 3.3V output but no EN control for system-level power sequencing | Select when ultra-low shutdown IQ is critical and enable functionality is unnecessary. |
| Torex XC6206P332MR-G | 300mA output, 200mV dropout at 300mA, 1µF min output cap, no EN pin | No enable function; slightly higher dropout limits usable input range in low-voltage battery designs | Choose for cost-sensitive, non-sequenced power rails where EN is not required. |
Compared with MCP1700T-3302E/TT and XC6206P332MR-G, the MIC5310-PPYMLTR uniquely combines 300mA capability, EN control, 60µA operating IQ, and 170mV dropout - making it optimal for battery-powered systems requiring dynamic power management and extended runtime.

FAQ
What is the minimum input voltage required for MIC5310-PPYMLTR to maintain regulation at full 300mA load?
The MIC5310-PPYMLTR maintains regulation down to 2.3V input. At 300mA load, its 170mV dropout requires a minimum input of 3.47V (3.3V + 0.17V) to sustain 3.3V output. Below that, output voltage drops linearly with input - a defined behavior per datasheet Section 6.2.
Does MIC5310-PPYMLTR require an external pull-up resistor on the EN pin?
No. The MIC5310-PPYMLTR EN pin has an internal weak pull-down and is active-high with CMOS-compatible thresholds. Driving EN directly from a GPIO or open-drain controller output is sufficient; no external pull-up is needed unless level-shifting or noise immunity is required in high-EMI environments.
Can MIC5310-PPYMLTR operate with a 0.47µF ceramic output capacitor?
No. The MIC5310-PPYMLTR requires a minimum of 1µF ceramic output capacitance for guaranteed stability across temperature and load conditions, as specified in the datasheet's "Stability Requirements" section. Using 0.47µF may cause oscillation or poor transient response.
Is MIC5310-PPYMLTR qualified for automotive applications?
No. The MIC5310-PPYMLTR is rated for industrial temperature range (–40°C to +125°C junction), but it is not AEC-Q200 qualified or automotive-grade screened. For automotive use, Microchip recommends the MIC5320 series, which includes AEC-Q200 variants.
How does the thermal foldback protection behave in MIC5310-PPYMLTR during sustained overload?
In MIC5310-PPYMLTR, thermal foldback begins at ~150°C junction temperature and linearly reduces output current as temperature rises - preventing thermal runaway while maintaining partial functionality. Once junction temperature falls below ~140°C, full 300mA capability resumes automatically without reset or latch.
