Product details
Overview
MIC5392-MFYMT-TR from Micrel is a dual-channel, fixed-output low-dropout linear regulator delivering 2.8V/1.5V at up to 150mA per channel, optimized for space-constrained portable electronics. It features ±2% output accuracy, 155mV dropout at full load, and >60dB PSRR at 1kHz - enabling clean power for camera DSPs and image sensors without bypass capacitors.
For engineers reviewing the MIC5392-MFYMT-TR datasheet, MIC5392-MFYMT-TR pinout, MIC5392-MFYMT-TR application, or MIC5392-MFYMT-TR equivalent, key selection criteria include independent enable control, µCap stability with 1µF ceramic outputs, thermal shutdown protection, and compatibility with 2.5–5.5V input systems in ultra-compact 1.2mm × 1.2mm Thin DFN packages.
Technical Context
The MIC5392-MFYMT-TR integrates two independent CMOS-based LDO regulators sharing a common input (VIN) and ground (GND), each with dedicated active-high enable pins (EN1, EN2) and output terminals (VOUT1, VOUT2). Its architecture supports simultaneous or staggered activation, with no cross-regulator coupling in regulation or transient response.
Each regulator employs internal bandgap reference, error amplifier, and PMOS pass device - achieving low quiescent current (32µA per LDO), fast turn-on time (≤125µs), and stable operation across –40°C to +125°C junction temperature. The exposed thermal pad (ePad) must be connected to GND for thermal performance and EMI reduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.8V (VOUT1) and 1.5V (VOUT2) - fixed, non-adjustable; enables direct powering of dual-rail image sensor interfaces. |
| Max Output Current | 150mA per channel - sufficient for CMOS image sensor analog/digital cores and camera DSPs without external boost. |
| Dropout Voltage | 155mV at 150mA - allows operation from 3.0V input to deliver 2.8V rail, maximizing battery runtime in 3.3V/3.0V systems. |
| PSRR | ≥60dB at 1kHz - suppresses switching noise from adjacent DC-DC converters, eliminating need for additional LC filtering. |
| Output Capacitor | Stable with ≥1µF X5R/X7R ceramic - reduces BOM count and PCB area vs. traditional LDOs requiring 10–22µF tantalum. |
| Quiescent Current | 32µA per enabled LDO - extends standby time in always-on camera modules and audio codec subsystems. |
| Enable Logic | Active-high (VIH ≥1.2V) - compatible with standard GPIOs; floating pins must be avoided to prevent erratic output behavior. |
Pinout & Package
Package: 6-pin 1.2mm × 1.2mm Thin DFN (MT), 0.4mm height, RoHS-compliant NiPdAu lead finish, halogen-free mold compound. Exposed thermal pad (ePad) must be soldered to GND plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT1 | Regulator 1 output | Delivers fixed 2.8V; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
| 2 - VOUT2 | Regulator 2 output | Delivers fixed 1.5V; independently regulated - unaffected by load or fault on VOUT1. |
| 3 - GND | Power and signal ground | Common return path for both regulators; must be low-impedance connection to ePad and system GND. |
| 4 - EN2 | Enable input for Regulator 2 | Logic high (≥1.2V) activates 1.5V rail; logic low disables output and reduces ground current to ≤1µA. |
| 5 - VIN | Main input supply | Accepts 2.5–5.5V; requires ≥1µF ceramic capacitor to GND close to pin for high-frequency decoupling. |
| 6 - EN1 | Enable input for Regulator 1 | Logic high (≥1.2V) activates 2.8V rail; independent control enables power sequencing for sensor startup. |
| ePad | Thermal and electrical ground | Exposed copper pad beneath package; must be fully soldered to GND plane for θJA = 173°C/W and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enable control | EN1 and EN2 allow precise power sequencing - e.g., enable 2.8V sensor analog rail before 1.5V digital core to avoid latch-up. |
| µCap-compatible stability | Operates stably with only 1µF ceramic output capacitors - cuts board area by >70% vs. legacy LDOs needing 10–22µF. |
| High PSRR without bypass caps | ≥60dB rejection at 1kHz eliminates need for large bulk capacitors or ferrite beads - simplifies layout in tight camera modules. |
| Low-noise output | 100µVRMS integrated noise (10Hz–100kHz) - preserves SNR in image sensor analog front-ends and audio codec references. |
| Robust fault protection | Integrated thermal shutdown and current limiting (200–550mA) prevent damage during short-circuit or overtemperature events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5392-PMYMT-TR | Fixed 3.0V/2.8V outputs; same package, pinout, and specs except output voltages. | Suitable for SoC I/O and core rail pairs where 3.0V/2.8V match processor requirements. | Select when system requires higher primary rail voltage; no layout change needed. |
| TCS2116-2815DBVR | 2.8V/1.5V dual LDO in 6-pin SOT-23; 250mA per channel, 220mV dropout, 45µA IQ. | Larger footprint (2.9mm × 1.6mm), higher dropout limits use in low-input-voltage systems. | Choose if SOT-23 assembly is preferred over DFN; verify thermal margin at 150mA due to higher θJA. |
Compared with MIC5392-MFYMT-TR, MIC5392-PMYMT-TR offers higher output voltage flexibility for modern SoCs, while TCS2116-2815DBVR provides higher current headroom but sacrifices board-area efficiency and PSRR performance.

FAQ
What are the exact output voltages of the MIC5392-MFYMT-TR?
The MIC5392-MFYMT-TR delivers fixed 2.8V on VOUT1 and 1.5V on VOUT2. These values are laser-trimmed during manufacturing and specified with ±2% initial accuracy over temperature and line/load conditions. No external resistors or configuration pins are required - the outputs are fully determined by the part number marking (RP code).
Can the MIC5392-MFYMT-TR operate with only one regulator enabled?
Yes - the MIC5392-MFYMT-TR supports independent operation: EN1 controls VOUT1 (2.8V) and EN2 controls VOUT2 (1.5V). Either regulator can be disabled while the other remains active, drawing only ≤1µA in shutdown. This enables dynamic power gating in camera modules where analog and digital sections power up at different times.
What is the minimum input voltage required for the MIC5392-MFYMT-TR to regulate at full load?
To maintain regulation at 150mA per channel, the MIC5392-MFYMT-TR requires VIN ≥ VOUT + dropout voltage. For VOUT1 (2.8V), minimum VIN is 2.8V + 0.155V = 2.955V; for VOUT2 (1.5V), it is 1.5V + 0.155V = 1.655V. Since both share VIN, the higher requirement governs: VIN must be ≥2.955V for full 150mA on VOUT1. Input range is rated 2.5–5.5V.
Does the MIC5392-MFYMT-TR require an input capacitor, and if so, what type?
Yes - the MIC5392-MFYMT-TR requires a minimum 1µF ceramic input capacitor from VIN to GND, placed as close as possible to the package. X5R or X7R dielectric types are recommended for stable capacitance over temperature and voltage. Y5V dielectrics are not recommended due to severe capacitance loss above 25°C.
Is thermal pad (ePad) connection mandatory for the MIC5392-MFYMT-TR?
Yes - the exposed thermal pad (ePad) must be soldered to a solid GND plane. It serves both thermal dissipation (reducing θJA to 173°C/W) and electrical grounding. Omitting ePad connection degrades thermal performance, risks thermal shutdown under load, and may increase EMI susceptibility. The datasheet specifies full-solder coverage for reliability.
