Product details
Overview
MIC5330-SPYML-TR from Micrel is a dual-channel ultra-low dropout (ULDO™) linear regulator delivering 300mA per channel with fixed 3.3V/3.0V outputs in an 8-pin 2mm × 2mm MLF® package. It features 75mV dropout at 300mA, 30µVRMS output noise, and >70dB PSRR at 1kHz-designed for powering RF-sensitive circuits such as cellular camera modules and digital imaging sensors.
For engineers reviewing the MIC5330-SPYML-TR datasheet, MIC5330-SPYML-TR pinout, MIC5330-SPYML-TR application, or MIC5330-SPYML-TR equivalent, key selection criteria include dual independent enable control (EN1/EN2), µCap compatibility with 1µF ceramic output capacitors, thermal shutdown protection, and operation across –40°C to +125°C junction temperature.
Technical Context
The MIC5330-SPYML-TR integrates two independent CMOS-based ULDO regulators sharing a common input but with separate enable inputs (EN1, EN2) and outputs (VOUT1 = 3.3V, VOUT2 = 3.0V). Each channel maintains regulation down to 75mV dropout at full 300mA load while rejecting supply ripple via high-bandwidth error amplifiers and internal reference bypassing.
Its µCap architecture eliminates need for large output capacitance-stability is ensured with ≥1µF low-ESR ceramic capacitors per output and an optional 0.1µF bypass capacitor on the BYP pin to reduce reference noise and improve PSRR beyond 1kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 3.3V (VOUT1) and 3.0V (VOUT2), fixed, ±2% initial accuracy |
| Dropout voltage | 75mV @ 300mA per LDO-enables regulation from 3.375V input for 3.3V rail and 3.075V for 3.0V rail |
| PSRR | >70dB @ 1kHz-suppresses switching noise from upstream DC/DC converters feeding RF/analog circuitry |
| Output noise | 30µVRMS (10Hz–100kHz)-minimizes phase noise in VCOs and jitter in high-speed sensor interfaces |
| Quiescent current | 75µA per output-supports always-on low-power subsystems without compromising battery life |
| Enable logic | Active-high EN1/EN2 with <0.2V logic low threshold-compatible with standard GPIOs and enables independent power sequencing |
| Thermal resistance | θJA = 90°C/W-supports 300mA per channel in compact 2mm × 2mm footprint with minimal heatsinking |
Pinout & Package
Package: 8-pin 2mm × 2mm leadless MLF® (MicroLeadFrame) with exposed thermal pad (EP) requiring connection to GND for optimal thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Common input supply | Accepts 2.3V–5.5V; must be bypassed with ≥1µF ceramic capacitor to GND |
| GND | Analog/digital ground reference | Return path for both LDOs and BYP capacitor; connects to EP for thermal conduction |
| BYP | Reference bypass terminal | Connects 0.1µF capacitor to GND to reduce output noise and improve PSRR above 1kHz |
| EN2 | Enable input for LDO2 (3.0V) | Active-high; drives LDO2 into zero-current shutdown when pulled low; must not float |
| EN1 | Enable input for LDO1 (3.3V) | Active-high; enables/disables 3.3V rail independently; supports staggered power-up sequencing |
| NC | No-connect terminal | Not internally bonded-must remain unconnected per datasheet |
| VOUT2 | Regulated 3.0V output | Delivers up to 300mA; requires ≥1µF ceramic output capacitor for stability |
| VOUT1 | Regulated 3.3V output | Delivers up to 300mA; decoupled separately from VOUT2 to prevent crosstalk in mixed-signal systems |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow precise sequencing of 3.3V and 3.0V rails-critical for FPGAs, image sensors, and baseband processors |
| µCap architecture | Stable with only 1µF ceramic output capacitors per rail-reduces PCB area and BOM cost vs. traditional LDOs requiring 10–22µF tantalum |
| Ultra-low noise output | 30µVRMS noise enables clean power for RF transceivers, PLLs, and high-resolution ADCs without additional filtering |
| Fast startup time | 30µs turn-on time (with 0.01µF BYP cap) supports dynamic power gating in portable devices |
| Thermal shutdown protection | Internally limits die temperature to ≤125°C-prevents damage during sustained overload or poor PCB thermal layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D333MR-G | Single-output 3.3V LDO (300mA), no second rail; 250mV dropout @ 300mA; 45µVRMS noise | Cannot replace dual-rail functionality-requires external 3.0V regulator or redesign | Select only if system can consolidate to single 3.3V rail or add discrete 3.0V LDO |
| Richtek RT9013-33PF | Single 3.3V LDO (300mA); 200mV dropout @ 300mA; 40µVRMS noise; SOT-23-5 package | Lacks 3.0V output and independent enable-no support for dual-rail sequencing or noise-isolated analog supply | Use only for cost-sensitive single-rail applications where size and noise are secondary concerns |
Compared with Torex XC6223D333MR-G and Richtek RT9013-33PF, the MIC5330-SPYML-TR uniquely delivers matched dual outputs with ultra-low dropout, sub-30µV noise, and independent enable control in a thermally optimized 2mm × 2mm footprint-making it irreplaceable for space-constrained, noise-sensitive dual-rail systems.

FAQ
What is the maximum input voltage rating for the MIC5330-SPYML-TR?
The MIC5330-SPYML-TR has an absolute maximum input voltage (VIN) rating of +6V. However, its operational input range is specified from +2.3V to +5.5V. Exceeding 5.5V may cause permanent damage even if within the absolute maximum limit, as internal protection circuits are not designed for sustained overvoltage operation. Always maintain VIN ≤ 5.5V in normal use.
Does the MIC5330-SPYML-TR require external capacitors for stability?
Yes, the MIC5330-SPYML-TR requires a minimum 1µF ceramic capacitor from VIN to GND and ≥1µF ceramic capacitor from each VOUT (VOUT1 and VOUT2) to GND for stability. A 0.1µF capacitor on the BYP pin is recommended to reduce output noise. These values are validated in the datasheet and essential for maintaining regulation under load transients and across temperature.
Can the MIC5330-SPYML-TR operate with no load on either output?
Yes, the MIC5330-SPYML-TR remains stable and in regulation with zero load on either or both outputs. This no-load stability is confirmed in the Applications 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.
What is the thermal performance of the MIC5330-SPYML-TR in its 2mm × 2mm MLF® package?
The MIC5330-SPYML-TR has a junction-to-ambient thermal resistance (θJA) of 90°C/W in the standard 2mm × 2mm MLF® footprint. At full 300mA per channel with 3.3V/3.0V outputs and 3.3V input, power dissipation reaches ~0.69W, limiting maximum ambient temperature to ~63°C without additional heatsinking or PCB copper area.
How does the BYP pin function in the MIC5330-SPYML-TR?
The BYP pin in the MIC5330-SPYML-TR connects to the internal voltage reference node. Adding a 0.1µF capacitor from BYP to GND reduces output voltage noise by bypassing reference fluctuations and improves PSRR above 1kHz. The datasheet confirms this configuration lowers 30µVRMS noise further and enables cleaner power for RF/analog circuits.
