Product details
Overview
MIC5356-JGYMME from Micrel is a dual-channel, micropower, low-dropout linear regulator delivering independent 2.5V and 1.8V outputs at up to 500mA each, with 70μA typical quiescent current (both outputs enabled), 350mV dropout at full load, and integrated active output discharge for rapid voltage decay during shutdown - ideal for battery-powered portable electronics requiring tight voltage tracking and fast power sequencing.
For engineers reviewing the MIC5356-JGYMME datasheet, MIC5356-JGYMME pinout, MIC5356-JGYMME application, or MIC5356-JGYMME equivalent, this page provides verified technical context, package-validated pin functions, real-world transient performance data, and confirmed alternative options for dual-output LDO replacement in space-constrained, thermally sensitive designs.
Technical Context
The MIC5356-JGYMME integrates two fully independent CMOS-based LDO regulators with active-high enable control (EN1/EN2), enabling selective power-up/down of each 500mA rail without affecting the other. Its µCap architecture stabilizes with only 2.2µF ceramic output capacitors per channel, eliminating need for bulk electrolytics.
Unlike the MIC5355 variant, MIC5356-JGYMME includes an internal 30Ω NFET discharge path per output activated when EN1 or EN2 is driven low, ensuring rapid VOUT1/VOUT2 collapse to ground - critical for safe power-down sequencing in multi-rail SoC systems and preventing back-powering of downstream circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 2.5V (VOUT1) and 1.8V (VOUT2); enables direct powering of core logic and I/O rails in modern processors. |
| Max Output Current | 500mA per channel; supports high-current digital subsystems without external pass devices. |
| Dropout Voltage | 350mV typical at 500mA; allows operation from 3.0V input to sustain 2.5V/1.8V rails with minimal headroom loss. |
| Quiescent Current | 70μA typical (both outputs enabled); extends battery life in always-on sensor or standby modes. |
| Shutdown Current | <1μA typical (both EN pins low); meets ultra-low-power requirements for deep-sleep states. |
| Output Discharge | 30Ω internal NFET per output; discharges 2.2µF load to <10% VOUT in <1ms, eliminating need for external bleed resistors. |
| PSRR | 60dB at 1kHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Resistance | θJA = 64.4°C/W (8-pin ePad MSOP); enables 500mA dual-rail operation up to 70°C ambient with standard PCB layout. |
Pinout & Package
Package: 8-pin ePad MSOP (MME) with exposed thermal pad (HSPAD) - requires solder connection to PCB ground plane for thermal management and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input supply rail | Accepts 2.5V–5.5V; must be decoupled with ≥2.2µF ceramic capacitor close to pin. |
| 2 - GND | Power ground reference | Common return for both LDOs and thermal pad; low-inductance connection essential for stability. |
| 3 - NC | No internal connection | Not bonded; must remain unconnected on PCB to avoid parasitic coupling. |
| 4 - EN2 | Active-high enable for VOUT2 (1.8V) | Drives high (≥1.2V) to activate 1.8V rail; floating state causes undefined output behavior. |
| 5 - EN1 | Active-high enable for VOUT1 (2.5V) | Independent control allows staggered startup/shutdown; CMOS input draws ≤1μA. |
| 6 - NC | No internal connection | Not bonded; must remain unconnected on PCB. |
| 7 - VOUT2 | 1.8V regulated output | Supplies I/O or memory rails; features auto-discharge when EN2 = low. |
| 8 - VOUT1 | 2.5V regulated output | Supplies core logic or analog subsystems; features auto-discharge when EN1 = low. |
| ePad - HSPAD | Thermal heatsink pad | Must be soldered to solid GND copper area with ≥4 thermal vias (0.3–0.35mm Ø) for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1/EN2 allow precise sequencing - e.g., power 2.5V rail before 1.8V rail, or disable I/O before core logic. |
| µCap stability | Guaranteed stable with only 2.2µF X5R/X7R ceramic output capacitors per rail, reducing board area and BOM count. |
| Auto-discharge circuit | 30Ω internal NFET per output pulls VOUT to GND within milliseconds upon disable - prevents latch-up in cascaded power domains. |
| ±2% output accuracy | Ensures reliable operation of 1.8V I/O interfaces and 2.5V analog circuits without external trimming or calibration. |
| Thermal + current limiting | Integrated protection prevents damage during overload or short-circuit events; automatic recovery after fault removal. |
| Low-noise operation | 146µVRMS (10Hz–100kHz) supports noise-sensitive analog sensors and RF front-ends without additional filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5356-SGYMME | Fixed 3.3V/1.8V outputs instead of 2.5V/1.8V; identical package, pinout, and discharge functionality. | Suitable where higher primary rail voltage is required (e.g., 3.3V microcontroller core), but incompatible for 2.5V-dependent loads. | Select only if system requires 3.3V instead of 2.5V; otherwise, not functionally substitutable. |
| TPL7407LDR | 7-channel 250mA NMOS FET array with integrated charge pump; no LDO regulation, no fixed 2.5V/1.8V outputs, no auto-discharge. | Designed for LED driver or logic-level translation, not precision voltage regulation; lacks thermal/current protection. | Not a functional alternative - differs fundamentally in architecture, regulation capability, and safety features. |
Compared with MIC5356-JGYMME, MIC5356-SGYMME offers identical form, fit, and function except for output voltage values, making it a viable option only in systems where 3.3V/1.8V rails replace 2.5V/1.8V. TPL7407LDR shares no regulatory or discharge capability and cannot serve as a drop-in or functional replacement.

FAQ
What is the output voltage configuration of the MIC5356-JGYMME?
The MIC5356-JGYMME delivers fixed, factory-trimmed output voltages: 2.5V on VOUT1 (pin 8) and 1.8V on VOUT2 (pin 7). These values are laser-trimmed during production and specified with ±2% initial accuracy over temperature and load. The MIC5356-JGYMME does not support adjustable outputs or external feedback networks - it is strictly a dual-fixed-voltage device.
Does the MIC5356-JGYMME include output discharge functionality?
Yes, the MIC5356-JGYMME incorporates an active discharge circuit on both outputs. When EN1 or EN2 is driven low, a 30Ω internal NFET connects the corresponding VOUT pin to GND, discharging external capacitors rapidly. This feature is exclusive to the MIC5356 family - the MIC5355-JGYMME lacks it. The MIC5356-JGYMME's discharge behavior is confirmed in the Electrical Characteristics table under "Auto-Discharge NFET Resistance".
What package type and thermal requirements apply to the MIC5356-JGYMME?
The MIC5356-JGYMME uses the 8-pin ePad MSOP (MME) package with an exposed thermal pad (HSPAD). To meet thermal specifications (θJA = 64.4°C/W), the HSPAD must be soldered to a dedicated GND copper pour and connected via ≥4 thermal vias (0.3–0.35mm diameter, 1mm pitch). Failure to implement this reduces power handling capability and risks thermal shutdown under 500mA dual-load conditions.
Can the MIC5356-JGYMME operate with ceramic output capacitors smaller than 2.2µF?
No - the MIC5356-JGYMME is characterized and guaranteed stable only with ≥2.2µF ceramic output capacitance per rail (X5R or X7R dielectric). Using smaller values risks oscillation or poor transient response, as confirmed in the Application Information section and Typical Characteristics plots. The MIC5356-JGYMME's µCap architecture is optimized for this minimum value; reducing it violates the validated design margin.
What is the maximum allowable input voltage for the MIC5356-JGYMME?
The absolute maximum input voltage for the MIC5356-JGYMME is +6V, but the recommended operating range is +2.5V to +5.5V, as stated in the Operating Ratings table. Exceeding 5.5V risks violating the safe operating area, especially under high load, due to increased power dissipation. The MIC5356-JGYMME's dropout specification (350mV at 500mA) assumes operation within this 2.5V–5.5V window.
