Product details
Overview
MIC5392-4CYMT-TR from Micrel is a dual-channel, fixed-output 3.3V/1.8V low-dropout linear regulator delivering 150mA per channel in a 1.2mm × 1.2mm Thin DFN-6 package. It features ±2% output accuracy, 155mV dropout at full load, 60dB PSRR at 1kHz, and independent CMOS enable pins - designed for powering camera DSPs and image sensor rails in space-constrained mobile devices.
For engineers reviewing the MIC5392-4CYMT-TR datasheet, MIC5392-4CYMT-TR pinout, MIC5392-4CYMT-TR application, or MIC5392-4CYMT-TR equivalent, key selection criteria include dual-rail voltage pairing (3.3V/1.8V), µCap stability with 1µF ceramic capacitors, thermal performance in ultra-small footprint, and independent enable control for power sequencing in portable electronics.
Technical Context
The MIC5392-4CYMT-TR integrates two independent LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated enable (EN1/EN2) and output (VOUT1/VOUT2) terminals. Its CMOS-based control architecture enables fast turn-on time (50–125µs) and ultra-low quiescent current (32µA per LDO).
It operates across 2.5V–5.5V input range with stable regulation under 100µA–150mA load per channel, supported by internal current limiting (200–550mA) and thermal shutdown. The device is optimized for no-load stability and requires no bypass capacitor due to high PSRR and µCap design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3V (VOUT1) and 1.8V (VOUT2) - fixed, matched pair for I/O and core rail separation in image sensors. |
| Max Output Current | 150mA per channel - sufficient for camera DSPs and CIS analog front-ends without thermal derating in 1.2mm² footprint. |
| Dropout Voltage | 155mV at 150mA - enables operation from 3.45V input to sustain 3.3V rail when battery drops below 3.6V. |
| PSRR | 60dB at 1kHz - suppresses switching noise from PMIC or DC-DC converters feeding VIN, eliminating need for additional filtering. |
| Quiescent Current | 32µA per LDO - minimizes standby power loss during partial-sleep modes in handheld devices. |
| Output Capacitor | Stable with 1µF ceramic (X5R/X7R) - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10µF tantalum. |
| Accuracy | ±2% initial, ±3% over –40°C to +125°C - ensures reliable logic-level compliance for 1.8V I/O and 3.3V analog circuitry. |
Pinout & Package
Package: 6-pin 1.2mm × 1.2mm Thin DFN (MT), 0.4mm max height, RoHS-compliant NiPdAu lead finish, exposed ePad for thermal conduction to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT1 | Regulator 1 output | Delivers fixed 3.3V; connects directly to camera module I/O supply rail with 1µF local decoupling. |
| VOUT2 | Regulator 2 output | Delivers fixed 1.8V; powers image sensor core logic or analog bias circuits requiring tight voltage tolerance. |
| GND | Common ground reference | Shared return path for both LDOs; must be low-impedance connection to ePad and system ground plane. |
| EN2 | Active-high enable for VOUT2 | Logic-high (>1.2V) enables 1.8V rail; tied low disables output and reduces leakage to <1µA. |
| VIN | Input supply | Accepts 2.5–5.5V; requires 1µF X5R/X7R ceramic capacitor to GND for high-frequency stability. |
| EN1 | Active-high enable for VOUT1 | Independent control of 3.3V rail; supports staggered power-up sequences to avoid inrush current peaks. |
| ePad | Thermal pad | Exposed copper pad beneath package; must be soldered to solid GND plane for θJA = 173°C/W thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow precise sequencing of 3.3V and 1.8V rails - critical for avoiding latch-up in CIS interfaces. |
| µCap architecture | Stable with 1µF ceramic output capacitors - eliminates bulk capacitance, saves >0.5mm² board area per rail. |
| High PSRR without bypass cap | 60dB rejection at 1kHz - removes need for secondary LC filtering, simplifying layout near noise-sensitive analog blocks. |
| Low dropout at full load | 155mV dropout at 150mA - extends usable battery life in single-cell Li-ion systems down to 3.45V input. |
| Thermal and current protection | Integrated thermal shutdown and foldback current limiting - prevents damage during short-circuit or overload on either output. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D331MR-G | Single 3.3V LDO only; no dual-output or 1.8V channel; 120mA rating; SOT-25 package (2.9mm × 2.8mm). | Cannot replace MIC5392-4CYMT-TR's dual-rail function; requires two devices and larger board area. | Select only if system uses discrete 3.3V/1.8V rails with separate enable control and larger package tolerance. |
| Ricoh RP512K331D-TR-F | Dual 3.3V/3.3V outputs; no 1.8V option; 200mA per channel; 1.6mm × 1.6mm DFN package. | Matches footprint size but lacks required 3.3V/1.8V voltage pairing; unsuitable for image sensor core/I/O separation. | Consider only for dual 3.3V applications like dual-interface peripherals where voltage matching is mandatory. |
Compared with XC6216D331MR-G and RP512K331D-TR-F, the MIC5392-4CYMT-TR uniquely delivers the exact 3.3V/1.8V rail combination in the smallest possible footprint with independent enable control - making it irreplaceable for camera module power architecture without redesigning PCB layout or power sequencing logic.

FAQ
What are the fixed output voltages of the MIC5392-4CYMT-TR?
The MIC5392-4CYMT-TR provides precisely trimmed fixed outputs of 3.3V on VOUT1 and 1.8V on VOUT2, as confirmed by Micrel's ordering information table and electrical characteristics section. This pairing is optimized for camera module I/O and core supply separation. The MIC5392-4CYMT-TR does not support adjustable or other voltage combinations - only the 3.3V/1.8V variant identified by the "4C" marking code.
Does the MIC5392-4CYMT-TR require external capacitors for stability?
Yes, the MIC5392-4CYMT-TR requires a 1µF X5R or X7R ceramic capacitor from VIN to GND and one 1µF ceramic capacitor per output (VOUT1 and VOUT2) to GND. These are mandatory for stability per the datasheet's Application Information section. Y5V or Z5U dielectrics are explicitly discouraged due to excessive capacitance drift over temperature, which may cause oscillation in the MIC5392-4CYMT-TR.
How does the enable functionality work on the MIC5392-4CYMT-TR?
The MIC5392-4CYMT-TR features two active-high CMOS enable inputs: EN1 controls VOUT1 (3.3V) and EN2 controls VOUT2 (1.8V). A logic high ≥1.2V enables the respective regulator; a logic low ≤0.2V shuts it down, reducing ground current to <1µA. Neither EN pin may float - doing so risks indeterminate output states. This independent control enables precise power sequencing critical in camera modules using the MIC5392-4CYMT-TR.
Is the MIC5392-4CYMT-TR compatible with lead-free reflow processes?
Yes, the MIC5392-4CYMT-TR uses a GREEN, RoHS-compliant 1.2mm × 1.2mm Thin DFN package with NiPdAu lead finish and halogen-free mold compound. Its maximum soldering temperature rating is 260°C for 10 seconds, fully compatible with standard lead-free reflow profiles. The exposed ePad must be soldered to a thermal pad on the PCB to ensure proper heat dissipation and meet θJA = 173°C/W specification for the MIC5392-4CYMT-TR.
What protection features are integrated into the MIC5392-4CYMT-TR?
The MIC5392-4CYMT-TR integrates thermal shutdown, foldback current limiting (200–550mA), and low-quiescent-current shutdown mode (<1µA). It also features robust ESD tolerance (2kV HBM) and absolute maximum ratings that guard against reverse voltage, overvoltage, and overtemperature faults. These protections operate autonomously without external components - ensuring reliability in portable electronics where the MIC5392-4CYMT-TR is deployed.
