Product details
Overview
MIC5355-JGYMME-TR from Micrel is a dual-channel, micropower, low-dropout linear regulator delivering two independent 500mA outputs at fixed 2.5V and 1.8V. It operates from 2.5V to 5.5V input, achieves 2% initial output accuracy, maintains stability with only 2.2µF ceramic output capacitors, and draws just 70µA quiescent current with both LDOs enabled-ideal for space-constrained, battery-powered portable electronics.
For engineers reviewing the MIC5355-JGYMME-TR datasheet, MIC5355-JGYMME-TR pinout, MIC5355-JGYMME-TR application, or MIC5355-JGYMME-TR equivalent, this device supports independent enable control, delivers fast load/line transient response, integrates thermal and current limiting protection, and requires no external compensation-enabling robust, low-noise dual-rail power delivery in smartphones, GPS units, and digital cameras.
Technical Context
The MIC5355-JGYMME-TR implements two fully independent CMOS-based LDO regulators sharing a common input but featuring separate EN1/EN2 logic-controlled enables and dedicated VOUT1/VOUT2 outputs. Each channel provides 500mA continuous output with 350mV typical dropout at full load and 146µVRMS integrated output noise (10Hz–100kHz).
It uses µCap architecture optimized for low-ESR ceramic capacitors, achieves <1µA shutdown current when both enables are low, and incorporates internal current-limit and thermal shutdown circuitry-no external components required for fault protection. The device is not equipped with auto-discharge functionality (reserved for MIC5356 variants).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V (LDO1) and 1.8V (LDO2), fixed-eliminates external feedback network and ensures precise rail generation for core/logic supplies. |
| Max Output Current | 500mA per channel-supports high-current digital subsystems such as baseband processors or image sensors without derating. |
| Dropout Voltage | 350mV typical at 500mA-enables operation with minimal headroom (e.g., 3.0V input → 2.5V/1.8V rails), extending battery life in single-cell Li-ion systems. |
| Quiescent Current | 70µA with both outputs enabled-reduces standby power loss in always-on subsystems like real-time clocks or sensor hubs. |
| Output Capacitor | Stable with ≥2.2µF ceramic-allows compact, low-BOM-count designs using standard 0402 X5R/X7R MLCCs; no tantalum or electrolytic required. |
| PSRR | 60dB at 1kHz-effectively suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Resistance | θJA = 64.4°C/W (ePad MSOP)-supports 0.85W dissipation at ≤70°C ambient in standard PCB layouts with thermal vias to ground plane. |
Pinout & Package
Package: 8-pin ePad MSOP (MME), thermally enhanced with exposed heatsink pad (HSPAD) requiring connection to PCB ground plane via thermal vias for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Supply Input | Common input for both LDOs; must be decoupled with ≥2.2µF ceramic capacitor to GND. |
| GND | Ground Reference | Analog/digital ground return; connects directly to HSPAD and system ground plane. |
| NC | No Connect | Pins 3 and 6 are unconnected internally-must remain unpopulated or floating (no routing). |
| EN2 | LDO2 Enable Input | Active-high CMOS input; drives LDO2 ON/OFF independently; must not float-tie to GND or logic rail. |
| EN1 | LDO1 Enable Input | Active-high CMOS input; controls LDO1 independently; shares same voltage domain and drive requirements as EN2. |
| VOUT2 | LDO2 Output | Regulated 1.8V supply; requires ≥2.2µF ceramic output capacitor to GND for stability. |
| VOUT1 | LDO1 Output | Regulated 2.5V supply; decoupled separately from VOUT2 to minimize cross-rail coupling. |
| HSPAD | Heatsink Pad | Exposed copper pad on bottom of package; must be soldered to solid GND plane with ≥4 thermal vias (0.3–0.35mm dia) for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1 and EN2 allow sequenced or asynchronous power-up/down of 2.5V and 1.8V rails-critical for FPGA I/O/core sequencing or processor sleep-state control. |
| µCap stability | Guaranteed stable with 2.2µF ceramic output caps-reduces board area, cost, and failure risk vs. larger or higher-ESR alternatives. |
| Low-noise regulation | 146µVRMS output noise (10Hz–100kHz)-meets stringent analog/RF supply requirements for ADCs, PLLs, or camera ISPs without added filtering. |
| Thermal + current protection | Integrated foldback current limit and thermal shutdown-prevents damage during overload or poor heatsinking without external circuitry. |
| No-load stability | Remains in regulation with zero output load-enables use in standby domains where one rail may be idle while the other remains active. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-micropower LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5356-JGYMME-TR | Includes active discharge (30Ω NFET per output) on disable; otherwise identical pinout, specs, and package. | Required where rapid output discharge is needed after shutdown (e.g., to meet system reset timing or avoid back-powering). | Select MIC5356-JGYMME-TR only if auto-discharge is explicitly required; MIC5355-JGYMME-TR is preferred for simpler, lower-leakage shutdown behavior. |
| TPL7407LPGEDR | Single 7-channel 150mA LDO array (not dual 500mA); different pinout, no independent enables, 1.8–5.5V input. | Suitable for multi-rail low-current biasing (e.g., display drivers), not high-current dual-core power. | Not a functional substitute-use only for distributed low-IQ biasing where per-channel current ≤150mA and independent enable is optional. |
Compared with MIC5356-JGYMME-TR, the MIC5355-JGYMME-TR omits auto-discharge-reducing complexity and leakage in always-on systems-while matching all electrical specs and pin compatibility. Unlike TPL7407LPGEDR, it delivers true dual 500mA capability with independent control, making it uniquely suited for high-current, tightly regulated dual-rail applications.

FAQ
What is the output voltage configuration of the MIC5355-JGYMME-TR?
The MIC5355-JGYMME-TR provides two fixed, non-adjustable output voltages: 2.5V on VOUT1 and 1.8V on VOUT2. These values are factory-trimmed to ±2% initial accuracy and cannot be modified externally. The marking "JG" in the part number explicitly denotes the 2.5V/1.8V variant per Micrel's ordering guide, and no resistor feedback network is used or supported.
Does the MIC5355-JGYMME-TR include an auto-discharge feature?
No, the MIC5355-JGYMME-TR does not include auto-discharge circuitry. That function is exclusive to the MIC5356 variant (e.g., MIC5356-JGYMME-TR), which integrates a 30Ω internal NFET between each output and ground when disabled. The MIC5355-JGYMME-TR leaves outputs floating upon disable, requiring external discharge paths if rapid voltage decay is needed.
What is the minimum output capacitance required for stability with the MIC5355-JGYMME-TR?
The MIC5355-JGYMME-TR requires a minimum of 2.2µF ceramic output capacitance per channel (COUT1 and COUT2) for guaranteed stability across temperature and load. X5R or X7R dielectric MLCCs in 0402 or 0603 case sizes are recommended; Y5V or Z5U types are discouraged due to excessive capacitance drift over temperature.
Can the MIC5355-JGYMME-TR operate with a 2.5V input supply?
Yes-the MIC5355-JGYMME-TR supports input voltages from 2.5V to 5.5V. However, at VIN = 2.5V, only the 1.8V output can regulate (since dropout is 350mV typical); the 2.5V output will be unregulated (VIN ≈ VOUT). For reliable 2.5V regulation, VIN must exceed 2.85V (2.5V + 350mV dropout) under full 500mA load.
Is the MIC5355-JGYMME-TR pin-compatible with other members of the MIC5355/6 family?
Yes-MIC5355-JGYMME-TR shares identical 8-pin ePad MSOP (MME) pinout and footprint with all MIC5355 and MIC5356 variants in the same package, including MIC5355-SGYMME, MIC5356-S4YMME, etc. Voltage differences are internal; EN1, EN2, VOUT1, VOUT2, VIN, GND, NC, and HSPAD positions remain unchanged across the family.
