Product details
Overview
MIC5380-KHYFT-TR from Micrel is a dual low-dropout linear regulator IC delivering two independent 150mA outputs at fixed 2.6V and 2.0V, housed in a 6-pin 1mm × 1mm Thin MLF® package. It features ±1% typical output accuracy, 155mV dropout at full load, and 32µA quiescent current per LDO-optimized for space-constrained, battery-powered portable electronics such as camera DSP power supplies and medical handhelds.
For engineers reviewing the MIC5380-KHYFT-TR datasheet, MIC5380-KHYFT-TR pinout, MIC5380-KHYFT-TR application, or MIC5380-KHYFT-TR equivalent, key selection criteria include dual-output voltage pairing, zero-off-mode shutdown (0.05µA), stability with 0402 1µF ceramic capacitors, and thermal protection across –40°C to +125°C junction range.
Technical Context
The MIC5380-KHYFT-TR integrates two CMOS-based LDO regulators with independent active-high enable inputs (EN1/EN2), enabling selective power gating of each output. Each regulator maintains regulation down to 0mA load and supports fast turn-on (50–125µs) with minimal ground current variation across input voltage (2.5V–5.5V) and temperature.
It employs internal current limiting (200–550mA) and thermal shutdown for fault protection, while its low-noise design (200µVRMS, 10Hz–100kHz) and high PSRR (60dB at 1kHz) ensure clean power delivery to noise-sensitive analog and mixed-signal blocks like camera image processors and RF front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.6V (VOUT1) and 2.0V (VOUT2) - fixed, non-adjustable; enables direct powering of core logic and I/O rails without external feedback networks. |
| Max Output Current | 150mA per LDO - sufficient to supply multiple low-power peripherals (e.g., sensor interfaces, Bluetooth baseband) from a single compact package. |
| Dropout Voltage | 155mV at 150mA - allows operation with minimal headroom (e.g., 2.75V input sustains 2.6V output), extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 32µA per LDO (active), 0.05µA total (shutdown) - minimizes standby drain in always-on subsystems like real-time clocks or wake-up controllers. |
| Accuracy | ±1% typical (±3% over –40°C to +85°C) - ensures reliable voltage margining for 2.6V/2.0V logic families without derating. |
| PSRR | 60dB at 1kHz - suppresses switching noise from upstream DC/DC converters, critical for ADC reference and PLL power domains. |
| Capacitor Support | Stable with 1µF 0402 ceramic output caps (X5R/X7R) - eliminates need for larger, board-area-consuming tantalum or electrolytic capacitors. |
Pinout & Package
Package: 6-pin 1mm × 1mm Thin MLF® (RoHS-compliant, NiPdAu lead finish, halogen-free mold compound). Pin 1 identified by ▲ mark (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | Regulated 2.6V output for primary load (e.g., processor core rail); requires local 1µF ceramic decoupling. |
| 2 | VOUT2 | Regulated 2.0V output for secondary load (e.g., interface I/O or memory); independently controllable via EN2. |
| 3 | EN2 | Active-high enable for VOUT2; must be pulled to VIN or GND - floating state causes indeterminate output behavior. |
| 4 | EN1 | Active-high enable for VOUT1; enables precise sequencing control (e.g., power VOUT1 before VOUT2 in boot-up). |
| 5 | GND | Common ground reference for both LDOs and enable inputs; requires low-impedance PCB connection to minimize noise coupling. |
| 6 | VIN | Input supply (2.5V–5.5V); accepts battery or DC/DC output; requires 1µF ceramic input capacitor to ground for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1mm × 1mm Thin MLF® package saves >70% board area vs. standard SOT-23 dual-LDO solutions - ideal for Bluetooth headsets and USB thumb drives. |
| Independent enable control | Separate EN1/EN2 pins allow dynamic power management of each rail - e.g., disable VOUT2 during sleep while keeping VOUT1 active for RTC. |
| Zero-off-mode shutdown | 0.05µA total shutdown current eliminates battery drain in storage or long-idle modes - critical for medical handhelds with multi-year shelf life. |
| Thermal & current protection | Integrated thermal shutdown and foldback current limiting prevent damage during overload or poor heatsinking - no external protection circuitry required. |
| No-load stability | Remains in regulation with 0mA load - supports CMOS RAM keep-alive applications without minimum load resistors or dummy loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5381-MGYFT | Same pinout and electrical specs, but adds auto-discharge (30Ω NFET) on both outputs when disabled. | Required where rapid output discharge is needed (e.g., hot-swap interfaces), not needed for basic power gating. | Select MIC5381-MGYFT only if output capacitor discharge time <1ms is mandatory; otherwise MIC5380-KHYFT-TR offers lower system complexity. |
| TPL7407LDR | 7-channel 250mA LDO array (not dual); 2.6V/2.0V not available - closest match is 3.3V/2.85V; larger 2mm × 2mm QFN package. | Suitable for multi-rail systems needing >2 outputs, not for strict size-constrained dual-rail use cases. | Choose TPL7407LDR only when expanding beyond two rails; MIC5380-KHYFT-TR remains optimal for minimal 2-rail, 1mm² footprint requirement. |
Compared with MIC5381-MGYFT, MIC5380-KHYFT-TR omits auto-discharge to reduce leakage risk and simplify biasing, making it preferable for always-on sensor nodes; versus TPL7407LDR, it delivers identical dual-voltage functionality in 75% less board area with tighter output tolerance.

FAQ
What are the fixed output voltages of the MIC5380-KHYFT-TR?
The MIC5380-KHYFT-TR provides two fixed, non-adjustable output voltages: 2.6V on VOUT1 and 2.0V on VOUT2. These values are laser-trimmed during manufacturing and cannot be modified externally. The marking code "KH" on the device body corresponds to this specific voltage pair, as confirmed in Micrel's official ordering information table.
Does the MIC5380-KHYFT-TR include an auto-discharge function?
No, the MIC5380-KHYFT-TR does not include auto-discharge. That feature is exclusive to the MIC5381 variant (e.g., MIC5381-MGYFT), which integrates a 30Ω NFET between each output and ground during shutdown. The MIC5380-KHYFT-TR relies on external discharge paths or natural capacitor leakage, making it suitable for applications where controlled discharge is unnecessary.
What is the minimum input voltage required for the MIC5380-KHYFT-TR to regulate at full load?
To maintain regulation at 150mA output current, the MIC5380-KHYFT-TR requires VIN ≥ VOUT + dropout voltage. With a maximum dropout of 310mV (over temperature), the minimum input is 2.6V + 0.31V = 2.91V for VOUT1 and 2.0V + 0.31V = 2.31V for VOUT2. Thus, 2.91V ensures both rails remain regulated under worst-case conditions.
Can the MIC5380-KHYFT-TR operate without load on either output?
Yes, the MIC5380-KHYFT-TR is explicitly designed for no-load stability. Unlike many LDOs, it remains in regulation with 0mA output current on either or both rails - a key feature verified in the "No-Load Stability" section of the datasheet and essential for CMOS RAM keep-alive and standby power domains.
What ceramic capacitor dielectric types are recommended for use with the MIC5380-KHYFT-TR?
X5R and X7R dielectric ceramic capacitors are recommended for both input and output use with the MIC5380-KHYFT-TR. These offer stable capacitance over temperature (±15% for X7R), unlike Y5V/Z5U types which can lose >50% value - ensuring consistent loop stability and transient response across –40°C to +125°C operation.
