Product details
Overview
MIC5320-SPYMT-TR from Micrel is a dual-channel ultra-low-dropout (ULDO™) linear regulator delivering 150mA per channel in a 1.6mm × 1.6mm Thin MLF® package. It provides fixed 3.3V and 3.0V outputs, operates from 2.3V to 5.5V input, achieves 35mV dropout at 150mA, and supports µCap stability with only 1µF ceramic output capacitors - ideal for space-constrained portable imaging sensors and camera modules.
For engineers reviewing the MIC5320-SPYMT-TR datasheet, MIC5320-SPYMT-TR pinout, MIC5320-SPYMT-TR application, or MIC5320-SPYMT-TR equivalent, this page delivers verified electrical parameters, validated thermal performance in the Thin MLF-6 package, confirmed dual enable control logic, and real-world design guidance for dual-rail power sequencing in mobile camera subsystems.
Technical Context
The MIC5320-SPYMT-TR integrates two independent CMOS-based ULDO regulators sharing a common VIN and GND, each with dedicated active-high enable inputs (EN1/EN2) and separate output pins (VOUT1/VOUT2). Its µCap architecture eliminates need for large bulk capacitance by enabling stable regulation with 1µF low-ESR ceramic capacitors on both input and output.
It features fast 30µs turn-on time, 90µVRMS output noise (10Hz–100kHz), 65dB PSRR at 1kHz, and thermal shutdown with current-limit protection. Junction temperature range is –40°C to +125°C, and its 100°C/W θJA enables 90.5°C max ambient operation at full 150mA load per channel with 3.3V/3.0V outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3V (VOUT1) and 3.0V (VOUT2), fixed, ±2% initial accuracy over temperature |
| Dropout Voltage | 35mV @ 150mA load - enables regulation down to VIN = VOUT + 0.035V, critical for battery-powered systems near end-of-life |
| Input Voltage Range | 2.3V to 5.5V - supports single-cell Li-ion (3.0–4.2V), USB 5V, and multi-rail intermediate supplies |
| Quiescent Current | 85µA per LDO - ensures minimal standby power draw in always-on camera sensor bias rails |
| Output Capacitor | 1µF ceramic minimum - reduces PCB area vs. traditional LDOs requiring ≥10µF, lowers BOM cost and improves transient response |
| Enable Logic | Active-high EN1/EN2 with 1.1V logic-high threshold - compatible with 1.8V/3.3V GPIOs; floating pins prohibited |
| Thermal Resistance | θJA = 100°C/W (Thin MLF-6) - allows 0.345W dissipation before thermal shutdown at 90.5°C ambient |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm leadless Thin MLF® (MT), RoHS-compliant, NiPdAu finish, exposed EPAD internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Supply Input | Common input for both LDOs; requires 1µF ceramic bypass to GND for stability |
| 2 (GND) | Ground Reference | Power and signal ground; connects to EPAD for thermal conduction |
| 3 (EN2) | Enable Input (LDO2) | Active-high control for 3.0V rail; must be pulled high (>1.1V) or low (<0.2V); never float |
| 4 (EN1) | Enable Input (LDO1) | Active-high control for 3.3V rail; independent sequencing enables staggered power-up of sensor and interface logic |
| 5 (VOUT2) | LDO2 Output | Regulated 3.0V supply for analog front-end or I/O voltage domain |
| 6 (VOUT1) | LDO1 Output | Regulated 3.3V supply for digital core or image signal processor (ISP) logic |
Key Features
| Feature | Design Value |
|---|---|
| µCap Stability | Stable with 1µF ceramic output caps - eliminates need for costly tantalum or large MLCCs, reducing footprint by >70% vs. legacy LDOs |
| Dual Independent Enables | EN1/EN2 allow precise power sequencing - e.g., enable 3.3V rail first for ISP boot, then 3.0V for sensor analog block |
| Ultra-Low Dropout | 35mV @ 150mA - extends usable battery life in single-cell Li-ion systems by maintaining regulation down to 3.035V input for 3.0V rail |
| Low Noise & High PSRR | 90µVRMS noise and 65dB PSRR @ 1kHz - preserves signal integrity in image sensor bias paths sensitive to supply ripple |
| Thermal Protection | Integrated thermal shutdown and current limit - prevents damage during sustained overload or poor PCB heatsinking |
Applications
| Mobile Camera Module Power | Digital Still Camera Sensor Bias |

FAQ
What are the exact output voltages of the MIC5320-SPYMT-TR?
The MIC5320-SPYMT-TR delivers precisely 3.3V on VOUT1 and 3.0V on VOUT2, with ±2% initial accuracy at 25°C and ±3% over the full –40°C to +125°C junction temperature range. These fixed outputs are laser-trimmed during manufacturing and require no external feedback components.
Can the MIC5320-SPYMT-TR operate with only one regulator enabled?
Yes - the MIC5320-SPYMT-TR supports independent operation: EN1 controls the 3.3V LDO (VOUT1), EN2 controls the 3.0V LDO (VOUT2). Either can be disabled (ENx = low) while the other remains active, drawing only 85µA quiescent current per enabled channel. This enables flexible power gating in camera subsystems.
What is the minimum output capacitor required for stability with the MIC5320-SPYMT-TR?
The MIC5320-SPYMT-TR requires a minimum 1µF X7R or X5R ceramic capacitor on each output (VOUT1 and VOUT2) for guaranteed stability. Larger values do not degrade performance but provide no significant improvement; Y5V/Z5U dielectrics are discouraged due to excessive capacitance drift over temperature.
Does the MIC5320-SPYMT-TR include thermal protection?
Yes - the MIC5320-SPYMT-TR integrates thermal shutdown and current-limit protection. When junction temperature exceeds +125°C or output current exceeds ~300mA (typical), the device disables both LDOs until conditions normalize. This protects against sustained overload or inadequate PCB heatsinking in compact camera modules.
Is the MIC5320-SPYMT-TR compatible with standard reflow soldering processes?
Yes - the MIC5320-SPYMT-TR uses a RoHS-compliant Thin MLF® package with NiPdAu lead finish and is rated for standard Pb-free reflow profiles, including peak temperatures up to 260°C for 3 seconds. The exposed EPAD enhances thermal transfer and must be soldered to a thermal pad on the PCB.
