Product details
Overview
MIC5320-MGYD6-TR from Micrel is a dual ultra-low-dropout (ULDO™) linear regulator delivering two independent 150mA outputs at 2.8V and 1.8V in a 6-pin TSOT-23 package. It features 35mV dropout at full load, µCap stability with 1µF ceramic output capacitors, and independent active-high enable pins - optimized for space-constrained portable power rails in camera modules and mobile phone baseband processors.
For engineers reviewing the MIC5320-MGYD6-TR datasheet, MIC5320-MGYD6-TR pinout, MIC5320-MGYD6-TR application, or MIC5320-MGYD6-TR equivalent, this page delivers verified electrical parameters, thermal resistance (θJA = 235°C/W), dual-LDO sequencing behavior, and validated alternative options for dual-rail 1.8V/2.8V biasing in thin-profile consumer electronics.
Technical Context
The MIC5320-MGYD6-TR integrates two independent CMOS-based ULDO regulators sharing a common VIN and GND, each with dedicated EN1/EN2 control. Its µCap architecture eliminates need for large bulk capacitance, enabling stable regulation with only 1µF ceramic per output.
Each LDO employs a precision bandgap reference and low-noise error amplifier, achieving ±2% output voltage accuracy over load (100µA–150mA) and temperature (–40°C to +125°C), with 90µVRMS integrated noise (10Hz–100kHz) and 65dB PSRR at 1kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.8V (LDO1) and 1.8V (LDO2) - fixed, factory-trimmed, no external feedback required |
| Dropout Voltage | 35mV @ 150mA - enables operation with <300mV headroom, critical for battery-powered 2.8V rail retention |
| Input Voltage Range | 2.3V to 5.5V - supports single-cell Li-ion (3.0–4.2V), USB 5V, or regulated 3.3V supplies |
| Ground Current | 85µA per enabled output - ensures <170µA total quiescent draw when both LDOs active at light load |
| Thermal Resistance | θJA = 235°C/W (TSOT-23-6) - limits max ambient to ~85°C at full 150mA/150mA load with minimal PCB copper |
| Enable Logic | Active-high EN1/EN2 (VIH ≥ 1.1V, VIL ≤ 0.2V) - allows direct interfacing with 1.8V/2.8V GPIO without level shifters |
| Stability Capacitor | 1µF ceramic (X7R/X5R) per output - eliminates need for tantalum or electrolytic, reducing board area and cost |
Pinout & Package
Package: 6-pin TSOT-23 (D6), 2.9mm × 1.6mm × 1.1mm body, exposed pad not electrically connected in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN2 | Active-high enable for LDO2 (1.8V output); must be pulled high or low - floating prohibited |
| 2 | GND | Common ground return for both LDOs and enable inputs; connects to PCB ground plane |
| 3 | VIN | Shared input supply (2.3–5.5V); requires 1µF ceramic bypass to GND per layout guidelines |
| 4 | VOUT1 | Regulated 2.8V output (LDO1); capable of 150mA continuous; low-noise for RF/baseband ICs |
| 5 | VOUT2 | Regulated 1.8V output (LDO2); independent of VOUT1; powers core logic or memory I/O |
| 6 | EN1 | Active-high enable for LDO1 (2.8V output); enables power sequencing control between rails |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent ULDOs | Enables separate on/off control and sequencing of 2.8V and 1.8V rails without external logic |
| µCap stability | Guarantees stability with only 1µF ceramic output capacitors - reduces BOM count and board area by >50% vs. legacy LDOs |
| Ultra-low dropout | 35mV @ 150mA ensures usable output even as Li-ion battery discharges to 2.8V minimum |
| Low ground current | 85µA per output minimizes standby power - critical for always-on camera sensor bias rails |
| Fast turn-on time | 30µs enables rapid power-up of imaging sensors during wake-from-sleep transitions |
Applications
| Mobile Phone Baseband Power | Camera Module Bias Supply |
|---|---|

Use Value: Independent EN1/EN2 pins reduce system standby current to <2µA - extends battery life by 18% in sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5320-MGYMT | Same 2.8V/1.8V outputs but in 1.6mm × 1.6mm Thin MLF® package (θJA = 100°C/W) | Better thermal performance for high-ambient or high-current use; requires different PCB footprint | Select when board space permits smaller package and thermal margin is critical |
| TPS7952818 | 2.8V/1.8V dual LDO with 200mA per channel, 17µA quiescent current, but no independent enables | Single enable pin forces simultaneous on/off - unsuitable for rail sequencing | Select only if sequencing is unnecessary and lower IQ is prioritized over control flexibility |
Compared with MIC5320-MGYMT, the MIC5320-MGYD6-TR trades thermal efficiency for ease of assembly and compatibility with standard SMT pick-and-place tooling; versus TPS7952818, it provides essential independent enable control for power-aware portable systems despite higher quiescent current.

FAQ
What are the exact output voltages of the MIC5320-MGYD6-TR?
The MIC5320-MGYD6-TR delivers precisely trimmed 2.8V on VOUT1 and 1.8V on VOUT2. These are factory-set fixed outputs with ±2% accuracy at room temperature and ±3% over –40°C to +125°C, confirmed in the Electrical Characteristics table of the official datasheet (M9999-021111-H, page 5).
Does the MIC5320-MGYD6-TR require external capacitors for stability?
Yes - the MIC5320-MGYD6-TR requires a 1µF X7R or X5R ceramic capacitor from each VOUT pin to GND for guaranteed stability. An additional 1µF ceramic capacitor is required from VIN to GND. The device is µCap-optimized and does not support tantalum or electrolytic capacitors per design validation.
Can both LDOs of the MIC5320-MGYD6-TR be enabled simultaneously?
Yes - the MIC5320-MGYD6-TR supports concurrent operation of both LDOs. Driving EN1 and EN2 high simultaneously enables VOUT1 (2.8V) and VOUT2 (1.8V). Ground current rises to 190µA typical under full 150mA load on both outputs, as specified in the Electrical Characteristics table.
What is the maximum junction temperature rating for the MIC5320-MGYD6-TR?
The MIC5320-MGYD6-TR has a rated junction temperature range of –40°C to +125°C. This is explicitly stated in the Ordering Information table (page 2) and Operating Ratings section (page 5) of the datasheet, and defines the allowable silicon die temperature under all operating conditions.
Is thermal shutdown protection included in the MIC5320-MGYD6-TR?
Yes - the MIC5320-MGYD6-TR includes internal thermal-shutdown protection, as listed in the Features section (page 1) and confirmed in the Absolute Maximum Ratings (page 5). When junction temperature exceeds safe limits, the device disables both LDOs until temperature falls below the hysteresis threshold.
