Product details
Overview
MIC5504-2.5YMT-TZ from Microchip Technology is a 300 mA fixed-output low-dropout (LDO) linear regulator with 2.5 V output, internal enable pull-down, and auto-discharge functionality. It operates from 2.5 V to 5.5 V input, delivers ±2% output accuracy over –40°C to +125°C, and features 160 mV dropout at full load - ideal for battery-powered portable electronics requiring fast turn-off and stable low-noise supply.
For engineers reviewing the MIC5504-2.5YMT-TZ datasheet, MIC5504-2.5YMT-TZ pinout, MIC5504-2.5YMT-TZ application, or MIC5504-2.5YMT-TZ equivalent, key selection criteria include its 1 mm × 1 mm Thin DFN package, 38 μA quiescent current, 25 Ω auto-discharge path, and compatibility with 1 μF ceramic output capacitors in space-constrained medical and consumer devices.
Technical Context
The MIC5504-2.5YMT-TZ integrates both auto-discharge and internal EN pull-down functions - distinguishing it from MIC5501/2/3 variants. Its enable pin is active-high with a 4 MΩ internal pull-down resistor, ensuring reliable disable behavior during processor boot-up when control signals float.
This LDO uses CMOS architecture to achieve low ground current (38 μA typical at no load), stable regulation down to zero load, and 60 dB PSRR at 1 kHz. It is thermally protected with current limiting (630 mA typical) and thermal shutdown, and is explicitly not suitable for RF transmitter systems per datasheet specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over –40°C to +125°C - ensures stable core voltage for low-power microcontrollers and sensors. |
| Max Output Current | 300 mA guaranteed - sufficient for powering SoCs, PMUs, and peripheral ICs in portable designs. |
| Dropout Voltage | 160 mV at 300 mA - enables operation from 2.75 V input while maintaining 2.5 V output, extending battery life. |
| Quiescent Current | 38 μA typical - minimizes standby power loss in always-on subsystems like real-time clocks or keep-alive RAM. |
| Auto-Discharge Path | 25 Ω NFET to GND when disabled - rapidly discharges output capacitance (<1 ms for 1 μF), preventing residual voltage hold-up. |
| Enable Input Logic | Active-high with 4 MΩ internal pull-down - eliminates need for external biasing; safe default-OFF state during cold boot. |
| Stability | Stable with ≥1 μF ceramic output capacitor - simplifies layout and reduces BOM count versus larger electrolytic solutions. |
Pinout & Package
Package: 4-Lead 1.0 mm × 1.0 mm Thin DFN (TDFN-4, MT), exposed thermal pad (ePAD) to be connected to GND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 4) | Input supply connection | Accepts 2.5 V–5.5 V; requires 1 μF ceramic decoupling to GND for stability and noise suppression. |
| EN (Pin 3) | Active-high enable input | Internal 4 MΩ pull-down ensures OFF state if left floating; logic-low disables regulator and activates discharge path. |
| VOUT (Pin 1) | Regulated output | Delivers fixed 2.5 V; auto-discharged via 25 Ω path to GND when EN = low - prevents back-powering downstream circuitry. |
| GND (Pin 2) | Ground reference and return path | Common return for VIN, VOUT, and ePAD; must be low-impedance connection to minimize noise and thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge + EN pull-down integration | Single-package solution eliminating external discharge FET and pull-down resistor - reduces PCB area and component count. |
| Ultra-small 1 mm × 1 mm TDFN package | Enables placement in tight spaces such as wearable sensor modules and compact IoT edge nodes where board area is premium. |
| Zero-load stability | Maintains regulation with no output load - critical for backup power rails feeding RTCs or non-volatile memory without leakage concerns. |
| Low-noise operation | 175 μVRMS output noise (10 Hz–100 kHz) - supports noise-sensitive analog circuits like ADC references and audio codecs. |
| Thermal & current protection | Integrated thermal shutdown and 630 mA current limit - prevents damage during short-circuit or overload conditions without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5502-2.5YMT-TR | Lacks internal EN pull-down; requires external pull-down resistor for safe floating EN state. | Suitable where system-level enable logic is actively driven and no boot-time floating risk exists. | Select MIC5502-2.5YMT-TR only if EN is always driven - avoids unnecessary pull-down overhead in controlled environments. |
| MCP1826-2502E/DB | Same 2.5 V output, 300 mA rating, but uses SOT-23-5 package and lacks auto-discharge function. | Used in cost-sensitive designs where output discharge is handled externally or not required. | Choose MCP1826-2502E/DB when board space permits larger SOT-23 and discharge is managed by system-level reset sequencing. |
Compared with MIC5502-2.5YMT-TR and MCP1826-2502E/DB, the MIC5504-2.5YMT-TZ uniquely combines auto-discharge and internal EN pull-down in the smallest footprint - reducing design complexity and improving reliability in uncontrolled boot scenarios and fast-power-cycle applications.

FAQ
What is the maximum input voltage rating for the MIC5504-2.5YMT-TZ?
The MIC5504-2.5YMT-TZ has an absolute maximum input voltage 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 violate functional specifications, even if within absolute max limits. Always maintain VIN ≤ 5.5 V in normal operation to ensure reliability and parameter compliance.
Does the MIC5504-2.5YMT-TZ require an external pull-down resistor on the EN pin?
No - the MIC5504-2.5YMT-TZ includes an internal 4 MΩ pull-down resistor on the EN pin, so no external resistor is needed. This ensures the output remains disabled during processor boot-up or when the enable signal is floating, making it ideal for systems with undriven control lines.
Can the MIC5504-2.5YMT-TZ operate with zero load current?
Yes - the MIC5504-2.5YMT-TZ remains stable and in regulation with no output load, a feature confirmed in Section 4.3 of the datasheet. This makes it suitable for applications like CMOS RAM keep-alive rails or always-on sensor bias supplies where load current may drop to zero.
What is the purpose of the auto-discharge function in the MIC5504-2.5YMT-TZ?
The auto-discharge function in the MIC5504-2.5YMT-TZ activates a 25 Ω internal NFET between VOUT and GND when EN is low, rapidly discharging external output capacitance. This prevents residual voltage from holding up downstream circuitry and supports clean power-down sequencing in portable and medical devices.
Is the MIC5504-2.5YMT-TZ suitable for RF transmitter applications?
No - the MIC5504-2.5YMT-TZ is explicitly stated in Section 4.0 of the datasheet as "not suitable for RF transmitter systems." Its PSRR and noise characteristics are optimized for general-purpose analog/digital loads, not the stringent spectral purity and transient response requirements of RF power amplifiers or transceivers.
