Product details
Overview
MIC5370-MFYMT-TR from Micrel is a dual low-dropout linear regulator delivering two independent 150mA outputs at fixed 2.8V and 1.5V, housed in a 1.6mm × 1.6mm Thin MLF® package. It features ±2% initial output accuracy, 155mV dropout at full load, 32μA typical ground current per LDO, and stable operation with only 1µF ceramic output capacitors - ideal for space-constrained portable power rails in camera modules and baseband processors.
For engineers reviewing the MIC5370-MFYMT-TR datasheet, MIC5370-MFYMT-TR pinout, MIC5370-MFYMT-TR application, or MIC5370-MFYMT-TR equivalent, key selection criteria include dual-rail voltage pairing (2.8V/1.5V), zero-off-mode shutdown current (<1µA), independent active-high enable control, thermal shutdown, and compatibility with standard 0402-size input/output ceramics.
Technical Context
The MIC5370-MFYMT-TR integrates two CMOS-based LDOs sharing a common VIN and GND but with separate EN1/EN2 controls and VOUT1/VOUT2 outputs. Each regulator uses internal bandgap reference and error amplifier feedback to maintain regulation across –40°C to +125°C junction temperature.
It operates within 2.5V–5.5V input range, supports fast transient response due to high bandwidth design, and achieves 60dB PSRR at 1kHz. Unlike the MIC5371 variant, it lacks auto-discharge circuitry - enabling true zero-current shutdown without output capacitor discharge loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 2.8V (VOUT1) and 1.5V (VOUT2); enables simultaneous core/peripheral rail generation without external resistors. |
| Max Output Current | 150mA per LDO; sufficient for powering DSP cores, image sensors, or RF front-end bias circuits. |
| Dropout Voltage | 155mV at 150mA load; allows operation with ≤300mV headroom - critical for battery-powered systems near end-of-life. |
| Ground Current | 32µA per LDO at light load; ensures ultra-low quiescent power draw during standby or partial-sleep modes. |
| Accuracy | ±2% initial tolerance; guarantees tight voltage margins for sensitive analog or low-voltage logic domains. |
| Stability | Guaranteed with ≥1µF X5R/X7R ceramic output capacitors; eliminates need for tantalum or electrolytic alternatives. |
| Enable Logic | Active-high EN1/EN2 pins; supports independent sequencing and dynamic power gating of each rail. |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm Thin MLF® (MT) with exposed thermal pad (internally connected to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Supply Input | Common input for both LDOs; must be decoupled with ≥1µF ceramic capacitor to GND. |
| 2 - GND | Ground Reference | System ground return path; connects internally to exposed heatsink pad for thermal dissipation. |
| 3 - EN2 | Enable Input (LDO2) | Active-high control for 1.5V output; logic low disables LDO2 and reduces ground current to <1µA. |
| 4 - EN1 | Enable Input (LDO1) | Active-high control for 2.8V output; independent of EN2 for flexible power sequencing. |
| 5 - VOUT2 | LDO2 Output | Regulated 1.5V supply; requires local 1µF ceramic capacitor to GND for stability. |
| 6 - VOUT1 | LDO1 Output | Regulated 2.8V supply; supports noise-sensitive analog blocks such as camera sensor analog front-ends. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Enables discrete voltage domain control - e.g., 2.8V for I/O interface and 1.5V for core logic - without cross-coupling. |
| Low dropout (155mV @ 150mA) | Extends usable battery life by maintaining regulation down to ~2.95V input when powering 2.8V rail. |
| Zero-off-mode shutdown | Draws <1µA total when both EN1 and EN2 are low - essential for long-term battery retention in always-on subsystems. |
| Thermal & current protection | Integrated thermal shutdown and foldback current limiting prevent damage during overload or PCB overheating events. |
| 1µF ceramic stability | Eliminates need for large or costly bulk capacitance - reduces BOM count and board area in compact mobile designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5371-MFYMT-TR | Same pinout and electrical specs, but adds auto-discharge (30Ω NFET) on both outputs during shutdown. | Required where rapid output capacitor discharge is needed to meet system reset timing or avoid back-powering. | Select MIC5371-MFYMT-TR if output discharge is mandatory; otherwise MIC5370-MFYMT-TR offers lower standby leakage. |
| Torex XC6216D2815MR-G | 2.8V/1.5V dual LDO in 6-pin SOT-363; higher 250mV dropout at 150mA and ±3% accuracy. | Suitable for cost-sensitive, non-precision applications where 1.6mm² footprint is not required. | Choose XC6216D2815MR-G only if SOT-363 assembly infrastructure exists and thermal performance margin is adequate. |
Compared with MIC5371-MFYMT-TR, the MIC5370-MFYMT-TR trades off auto-discharge capability for lower shutdown current; versus XC6216D2815MR-G, it delivers superior dropout, accuracy, and package size - making it optimal for high-density, battery-critical portable designs.

FAQ
What is the output voltage configuration of the MIC5370-MFYMT-TR?
The MIC5370-MFYMT-TR provides fixed 2.8V on VOUT1 and 1.5V on VOUT2. These values are laser-trimmed during manufacturing and cannot be adjusted externally. The "MF" marking code in the ordering table explicitly denotes this 2.8V/1.5V combination, and the device requires no external feedback components to maintain regulation.
Does the MIC5370-MFYMT-TR include output auto-discharge functionality?
No, the MIC5370-MFYMT-TR does not include auto-discharge circuitry. That feature is exclusive to the MIC5371 variant (e.g., MIC5371-MFYMT-TR). When disabled, the MIC5370-MFYMT-TR enters zero-off-mode with <1µA total supply current but leaves the output capacitors charged - requiring external discharge paths if system-level reset timing demands it.
What is the minimum input voltage required for the MIC5370-MFYMT-TR to regulate both outputs?
To maintain regulation on the 2.8V output at full 150mA load, the MIC5370-MFYMT-TR requires VIN ≥ 2.955V (2.8V + 155mV dropout). For the 1.5V output, VIN ≥ 1.655V suffices - but since both share VIN, the higher 2.8V rail dictates the minimum. Thus, 2.955V is the practical lower limit for simultaneous full-load operation.
Can the MIC5370-MFYMT-TR operate without load on either output?
Yes, the MIC5370-MFYMT-TR remains stable and in regulation with zero load on either or both outputs. This no-load stability is confirmed in the datasheet's Application Information section and is critical for applications like CMOS RAM keep-alive circuits or standby power domains where one rail may be inactive while the other remains active.
Which ceramic capacitor dielectrics are recommended for use with the MIC5370-MFYMT-TR?
X5R and X7R dielectric ceramic capacitors are recommended for both input and output. They provide stable capacitance over temperature (±15% for X7R) and low ESR, ensuring stability and transient performance. Y5V and Z5U dielectrics are explicitly discouraged due to excessive capacitance loss (>50%) across operating temperature ranges, risking instability.
