Product details
Overview
MIC5504-3.0YMT-TZ from Microchip Technology is a 300 mA, fixed 3.0 V output low-dropout linear regulator with auto-discharge and internal enable pull-down, operating from 2.5 V to 5.5 V input, delivering ±2% output accuracy and 160 mV dropout at full load - ideal for battery-powered portable electronics requiring fast output discharge and robust boot-up behavior.
For engineers reviewing the MIC5504-3.0YMT-TZ datasheet, MIC5504-3.0YMT-TZ pinout, MIC5504-3.0YMT-TZ application, or MIC5504-3.0YMT-TZ equivalent, this device is selected for compact, low-quiescent-current power management in space-constrained systems where controlled shutdown, output voltage stability across temperature, and ceramic capacitor compatibility are critical design requirements.
Technical Context
The MIC5504-3.0YMT-TZ integrates dual functional enhancements over base LDO variants: an active-low-triggered 25 Ω auto-discharge NFET on VOUT and an internal 4 MΩ pull-down resistor on the EN pin - eliminating external components needed for safe output discharge and floating-enable immunity during processor initialization.
It operates across –40°C to +125°C junction temperature, supports stable regulation with only 1 μF ceramic input/output capacitors, and achieves 60 dB PSRR at 1 kHz while maintaining 38 μA quiescent current in active mode and sub-1 μA shutdown current - enabling long battery life in always-on subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% (–40°C to +125°C), ensuring stable rail for 3.3 V–tolerant logic without external feedback. |
| Max Output Current | 300 mA guaranteed, supporting moderate-power peripherals like sensors, RF front-ends, or MCU cores. |
| Dropout Voltage | 160 mV @ 300 mA, enabling operation down to 3.16 V input - critical for single-cell Li-ion or Li-poly systems near end-of-discharge. |
| Quiescent Current | 38 μA typical, minimizing standby power loss in battery-backed real-time clocks or memory keep-alive circuits. |
| Enable Function | Active-high EN with internal 4 MΩ pull-down, preventing unintended turn-on when control signal is unasserted or tri-stated. |
| Auto-Discharge | 25 Ω internal NFET activated when EN = low, discharging output capacitance rapidly - essential for safe power sequencing and leakage control. |
| Capacitor Support | Stable with ≥1 μF X5R/X7R ceramic capacitors on input and output - eliminates need for tantalum or electrolytic types. |
Pinout & Package
Package: 4-Lead 1.0 mm × 1.0 mm Thin DFN (TDFN-4, MT), ePAD exposed thermal pad (to be connected to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 4) | Supply Input | Accepts 2.5 V–5.5 V input; requires 1 μF ceramic decoupling to GND for stability. |
| EN (Pin 3) | Enable Control | Active-high logic input; internal 4 MΩ pull-down ensures default OFF state if left floating. |
| VOUT (Pin 1) | Regulated Output | Delivers fixed 3.0 V; includes auto-discharge path (25 Ω) to GND when EN = low. |
| GND (Pin 2) | Ground Reference | Power and signal return; must be connected to PCB ground plane and ePAD for thermal performance. |
| ePAD | Thermal Heatsink | Exposed copper pad under package; soldering to solid GND plane reduces θJA to 250°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-Discharge Circuit | 25 Ω internal NFET on VOUT enables rapid capacitor discharge during shutdown - prevents residual voltage from interfering with downstream logic states. |
| Internal Enable Pull-Down | 4 MΩ resistor on EN pin guarantees defined OFF state during MCU reset or boot - no external resistor required. |
| Ultra-Low Quiescent Current | 38 μA typical active IQ and <1 μA shutdown current extend battery life in always-on applications such as wearables or medical monitors. |
| Small-Signal Stability | Guaranteed stability with 1 μF ceramic COUT, eliminating ESR sensitivity and simplifying layout in high-density portable PCBs. |
| Robust Protection | Integrated thermal shutdown and current limiting prevent damage during overload or short-circuit events - no external protection circuitry needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5504-3.0YMT-TR | Same electrical specs and package; differs only in tape-and-reel quantity (5,000 vs. 10,000 units per reel). | No functional difference; suitable for same designs but optimized for medium-volume production runs. | Select MIC5504-3.0YMT-TZ for high-volume manufacturing with reduced handling frequency per reel. |
| TPS7A0530PDBVR | 300 mA, 3.0 V fixed LDO with 25 μA IQ, but lacks auto-discharge and EN pull-down; requires external components for equivalent functionality. | Not drop-in compatible: needs external 10 MΩ pull-down and discharge FET for same safety and sequencing behavior. | Choose only if system already implements external discharge/pull-down and prioritizes lowest possible IQ over integration. |
Compared with MIC5504-3.0YMT-TR, the TZ variant offers higher reel quantity for line efficiency; compared with TPS7A0530PDBVR, it delivers integrated auto-discharge and EN pull-down - reducing component count, layout complexity, and risk of sequencing faults in portable designs.

FAQ
What is the maximum input voltage rating for the MIC5504-3.0YMT-TZ?
The MIC5504-3.0YMT-TZ has an absolute maximum input voltage (VIN) rating of +6 V, but its specified operating input range is +2.5 V to +5.5 V. Exceeding 5.5 V may cause permanent damage or unpredictable behavior, even if within the absolute maximum limit. Always operate within the recommended 2.5–5.5 V range for reliable performance of the MIC5504-3.0YMT-TZ.
Does the MIC5504-3.0YMT-TZ require an external pull-down resistor on the EN pin?
No, the MIC5504-3.0YMT-TZ includes an internal 4 MΩ pull-down resistor on the EN pin, ensuring the output remains disabled when the enable signal is floating or unconnected - a key differentiator from MIC5501/MIC5502 variants. This eliminates the need for external components and improves boot-up reliability in the MIC5504-3.0YMT-TZ.
What is the purpose of the auto-discharge feature in the MIC5504-3.0YMT-TZ?
The auto-discharge feature in the MIC5504-3.0YMT-TZ activates a 25 Ω internal NFET between VOUT and GND when the EN pin is driven low, rapidly discharging external output capacitance. This prevents residual voltage from powering downstream circuitry unintentionally and supports safe, repeatable power sequencing - a core function of the MIC5504-3.0YMT-TZ not present in MIC5501 or MIC5503.
Can the MIC5504-3.0YMT-TZ operate with a 1 µF ceramic output capacitor?
Yes, the MIC5504-3.0YMT-TZ is explicitly designed and tested for stability with a minimum 1 μF X5R or X7R ceramic output capacitor. Larger values do not degrade performance but provide no significant improvement; using Y5V or Z5U dielectrics is discouraged due to excessive capacitance loss over temperature - confirmed in the MIC5504-3.0YMT-TZ datasheet.
What is the thermal resistance (θJA) of the MIC5504-3.0YMT-TZ package?
The MIC5504-3.0YMT-TZ uses a 4-Lead 1.0 mm × 1.0 mm Thin DFN (MT) package with a junction-to-ambient thermal resistance (θJA) of 250°C/W under standard JEDEC PCB conditions. Effective thermal performance depends on proper ePAD soldering to a solid GND plane - the MIC5504-3.0YMT-TZ datasheet specifies this value as critical for calculating maximum ambient temperature at 300 mA load.
