Product details
Overview
MIC5501-3.0YM5-T5 from Microchip Technology is a 300 mA fixed-output 3.0 V low-dropout linear regulator in a 5-lead SOT23 package, operating from 2.5 V to 5.5 V input, delivering ±2% output accuracy, 160 mV dropout at full load, and 38 μA quiescent current - ideal for powering battery-sensitive portable electronics such as GPS modules and medical wearables.
For engineers reviewing the MIC5501-3.0YM5-T5 datasheet, MIC5501-3.0YM5-T5 pinout, MIC5501-3.0YM5-T5 application, or MIC5501-3.0YM5-T5 equivalent, key selection criteria include guaranteed 300 mA output under 160 mV dropout, stability with 1 μF ceramic capacitors, zero-off-mode shutdown current (<1 μA), thermal shutdown protection, and compatibility with –40°C to +125°C junction temperature operation.
Technical Context
The MIC5501-3.0YM5-T5 implements a CMOS-based LDO architecture optimized for ultra-low quiescent current and fast transient response in space-constrained applications. It features active-high enable control with no internal pull-down (requires externally driven EN), no auto-discharge circuitry, and operates without minimum load requirements - remaining stable down to 0 mA output current.
Its thermal protection engages at +125°C junction temperature, and its ground current remains tightly regulated across load (38 μA typ. at no load; 42–65 μA at 300 mA), enabling predictable power budgeting in always-on subsystems like real-time clock keep-alive rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over –40°C to +125°C - ensures stable core logic or sensor biasing without external feedback. |
| Max Output Current | 300 mA guaranteed - supports moderate-power microcontrollers, RF transceivers, or display drivers in compact designs. |
| Dropout Voltage | 160 mV at 300 mA - enables regulation from 3.16 V input, critical for single-cell Li-ion or Li-poly systems. |
| Quiescent Current | 38 μA typical at no load - minimizes standby power loss in battery-backed applications. |
| Input Voltage Range | 2.5 V to 5.5 V - compatible with USB-powered, multi-cell, or wide-input industrial supplies. |
| PSRR | 60 dB at 1 kHz - suppresses ripple from noisy switching regulators feeding the LDO input. |
| Thermal Shutdown | Activates at +125°C junction - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
Package: 5-Lead SOT23 (M5), 1.6 mm × 2.9 mm × 1.1 mm body height, ePAD optional but not present in SOT23 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 4) | Supply Input | Accepts 2.5–5.5 V; requires 1 μF ceramic capacitor to GND for stability and high-frequency noise filtering. |
| EN (Pin 3) | Enable Input | Active-high CMOS input; must be driven externally - floating state causes indeterminate output (no internal pull-down). |
| VOUT (Pin 5) | Regulated Output | Delivers fixed 3.0 V; stable with ≥1 μF ceramic output capacitor; no minimum load required. |
| GND (Pin 2) | Ground Reference | Primary return path for load and quiescent current; connects to system ground plane for thermal and noise control. |
| NC (Pin 1) | No Connection | Not internally bonded; electrically isolated - must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-off-mode shutdown | Draws <1 μA when EN = 0 V - eliminates battery drain in powered-off states of portable devices. |
| Stable with 1 μF ceramic capacitors | Eliminates need for larger, higher-ESR electrolytics - reduces board area and cost while improving reliability. |
| No-load regulation | Maintains 3.0 V output at 0 mA load - essential for RTC, backup memory, or wake-up circuitry requiring continuous bias. |
| Low dropout at full load | 160 mV dropout at 300 mA enables use in tight voltage-margin systems where headroom is constrained. |
| Wide temperature operation | Specified from –40°C to +125°C junction - suitable for automotive cabin, industrial edge, and medical environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5501-3.0YMT-T5 | Same electrical specs, but in 4-lead 1.0 mm × 1.0 mm TDFN package - smaller footprint, exposed thermal pad, no NC pin. | Better thermal performance (θJA = 250°C/W vs. 253°C/W) and higher density layout; requires different land pattern. | Select for space-constrained PCBs needing improved thermal dissipation; verify EN drive strength compatibility. |
| TPS7A0530PDBVR | 300 mA, 3.0 V fixed, 25 μA IQ, 170 mV dropout at 300 mA; SOT23-5 package; includes integrated thermal foldback. | Lower quiescent current but slightly higher dropout; tighter initial accuracy (±1%) but narrower input range (1.4–5.5 V). | Prefer for ultra-low-power designs where sub-30 μA IQ is critical; validate startup behavior with weak EN sources. |
Compared with MIC5501-3.0YMT-T5, the MIC5501-3.0YM5-T5 trades minimal thermal advantage for simplified routing (no ePAD), while versus TPS7A0530PDBVR, it offers broader input voltage tolerance and proven robustness in portable consumer designs - making it optimal for cost-sensitive, thermally moderate applications requiring field-proven reliability.

FAQ
What is the maximum input voltage rating for the MIC5501-3.0YM5-T5?
The MIC5501-3.0YM5-T5 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 functional instability or permanent damage, even if within the absolute maximum limit. For reliable operation, maintain VIN within 2.5–5.5 V per the datasheet's operating ratings section.
Does the MIC5501-3.0YM5-T5 include an internal pull-down resistor on the EN pin?
No, the MIC5501-3.0YM5-T5 does not include an internal pull-down resistor on the EN pin. As confirmed in the datasheet's Pin Descriptions and Application Information sections, only MIC5503 and MIC5504 variants feature this function. The MIC5501-3.0YM5-T5 requires an external pull-down or active driver to prevent floating EN states that could result in unpredictable output behavior.
Can the MIC5501-3.0YM5-T5 operate without an output capacitor?
No, the MIC5501-3.0YM5-T5 requires a minimum 1 μF ceramic output capacitor connected from VOUT to GND for stability, as explicitly stated in Section 4.2 of the datasheet. Omitting it risks oscillation or regulation failure. Unlike some LDOs, it is not designed for no-capacitor operation - the 1 μF value is both necessary and sufficient for stable performance.
What is the typical ground current of the MIC5501-3.0YM5-T5 at 300 mA load?
The typical ground current (IGND) of the MIC5501-3.0YM5-T5 at 300 mA load is 42 μA, with a maximum of 65 μA over temperature, per the Electrical Characteristics table on page 3 of DS20006006B. This includes both quiescent current and load-dependent contributions, enabling accurate total input current calculation: IIN = IOUT + IGNDD.
Is the MIC5501-3.0YM5-T5 suitable for RF transmitter applications?
No, the MIC5501-3.0YM5-T5 is explicitly stated as "not suitable for RF transmitter systems" in Section 4.0 of the datasheet. Its PSRR and noise performance - while adequate for digital and analog sensor rails - do not meet the stringent spectral purity and transient rejection requirements of RF power amplifiers or upconversion stages.
