Product details
Overview
MIC5387-GMGYMT-TR from Micrel is an ultra-small triple-output LDO regulator delivering 150mA per channel with fixed output voltages of 1.8V, 2.8V, and 1.8V, ±2% initial accuracy, 180mV dropout at 150mA, and 70dB PSRR - designed for space-constrained portable electronics requiring stable multi-rail power.
For engineers reviewing the MIC5387-GMGYMT-TR datasheet, MIC5387-GMGYMT-TR pinout, MIC5387-GMGYMT-TR application, or MIC5387-GMGYMT-TR equivalent, key selection criteria include triple-output voltage configuration, 6-pin 1.6mm × 1.6mm Thin MLF® package footprint, enable control for outputs 2/3 only, and thermal performance under simultaneous 150mA loads.
Technical Context
The MIC5387-GMGYMT-TR integrates three independent CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), with EN2/3 enabling both LDO2 and LDO3 simultaneously while LDO1 remains always-on. Each regulator features internal current limiting and thermal shutdown.
It operates across 2.5V–5.5V input, supports ceramic output capacitors ≥1µF per rail, and maintains stability without load - critical for low-power standby modes in battery-powered systems. Ground current is 32µA per enabled output at light load, rising to ≤120µA total under full 450mA combined load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.8V (OUT1), 2.8V (OUT2), 1.8V (OUT3) - fixed, non-adjustable, matched for dual-core SoC I/O + core rails |
| Max Output Current | 150mA per output - supports simultaneous operation of three low-power subsystems (e.g., RF transceiver, sensor hub, memory) |
| Dropout Voltage | 180mV @ 150mA - enables regulation from 3.0V input to 2.8V rail, minimizing wasted headroom in Li-ion systems |
| PSRR | 70dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding VIN |
| Accuracy | ±2% initial, ±3% over −40°C to +125°C - ensures reliable logic-level compliance for 1.8V/2.8V interfaces |
| Quiescent Current | 32µA per enabled output - extends battery life in always-on sensor nodes with periodic wake-up |
| Package | 6-pin 1.6mm × 1.6mm Thin MLF® - occupies only 2.56mm² PCB area, halving footprint vs. discrete dual-LDO solutions |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm Thin MLF® (MT) with exposed thermal pad (EP) - RoHS-compliant, NiPdAu lead finish, halogen-free mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Common ground reference | Shared return path for all three LDOs; must connect to solid ground plane via EP for thermal management |
| 2 (VIN) | Input supply node | Single 2.5–5.5V input powering all three regulators; requires 1µF X5R/X7R ceramic decoupling |
| 3 (EN2/3) | Enable control for LDO2 & LDO3 | Active-high CMOS input; drives both 2.8V and second 1.8V rails; must not float - tie to VIN or MCU GPIO |
| 4 (OUT3) | Output of third LDO | Fixed 1.8V rail; requires ≥1µF ceramic capacitor to ground for stability |
| 5 (OUT2) | Output of second LDO | Fixed 2.8V rail; shares EN2/3 enable with OUT3; independent current limiting |
| 6 (OUT1) | Output of first LDO | Fixed 1.8V rail; always active when VIN ≥2.5V; no enable control |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output integration | Eliminates need for three separate SOT-23 LDOs, reducing BOM count and PCB area by >60% |
| No-load stability | Remains in regulation with zero load - essential for maintaining backup RAM voltage during deep sleep |
| Ceramic capacitor compatibility | Stable with 1µF X5R/X7R ceramics on all inputs/outputs - avoids costly tantalum or electrolytic alternatives |
| Thermal shutdown & current limit | Protects against short-circuit or overload on any output without external circuitry - improves system reliability |
| Low-noise operation | 125–152µVRMS output noise (10Hz–100kHz) - suitable for analog sensors and RF front-end biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70245PWPR | 250mA dual-output (not triple); 1.8V/2.8V config; higher quiescent current (125µA) | Lacks third 1.8V rail; requires external regulator for third rail | Select if higher output current needed for one rail and board space allows discrete supplement |

FAQ
What are the fixed output voltages of the MIC5387-GMGYMT-TR?
The MIC5387-GMGYMT-TR provides three fixed output voltages: OUT1 = 1.8V, OUT2 = 2.8V, and OUT3 = 1.8V. These values are laser-trimmed during manufacturing and cannot be adjusted externally. The marking code "8C7" on the device confirms this specific voltage combination per the Micrel ordering table.
Does the MIC5387-GMGYMT-TR require external capacitors, and what type is recommended?
Yes, the MIC5387-GMGYMT-TR requires a 1µF X5R or X7R ceramic capacitor from VIN to GND and a 1µF X5R or X7R ceramic capacitor from each output (OUT1, OUT2, OUT3) to GND. Y5V and Z5U dielectrics are explicitly discouraged due to excessive capacitance loss over temperature, which risks instability.
How does enable control work on the MIC5387-GMGYMT-TR?
The MIC5387-GMGYMT-TR has a single active-high enable pin (EN2/3, Pin 3) that simultaneously controls LDO2 and LDO3 only. LDO1 (OUT1) is always enabled when VIN exceeds 2.5V. EN2/3 must be driven to ≥1.2V to activate the 2.8V and second 1.8V rails; leaving it floating may cause unpredictable behavior.
What is the thermal performance of the MIC5387-GMGYMT-TR under full load?
With all three outputs delivering 150mA (450mA total), VIN = 3.3V, and VOUTs = 1.8V/2.8V/1.8V, the MIC5387-GMGYMT-TR dissipates ~0.375W. Using its θJA = 92.4°C/W, the maximum ambient temperature for safe operation at TJ = 125°C is ~90°C - assuming proper thermal pad connection to a ground plane.
Is the MIC5387-GMGYMT-TR suitable for automotive applications?
No - the MIC5387-GMGYMT-TR is rated for −40°C to +125°C junction temperature but is not AEC-Q200 qualified or specified for automotive use. Micrel did not release automotive-grade variants of the MIC5387 family, and the device lacks required qualification testing, extended lifetime validation, and failure-in-time (FIT) data for automotive systems.
