Product details
Overview
MIC5380-PPYFT-TR from Micrel is a dual low-dropout linear regulator IC delivering two independent 3.0V/150mA outputs 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 systems such as portable medical devices and USB peripherals.
For engineers reviewing the MIC5380-PPYFT-TR datasheet, MIC5380-PPYFT-TR pinout, MIC5380-PPYFT-TR application, or MIC5380-PPYFT-TR equivalent, key selection criteria include dual-output independence, zero-off-mode shutdown (0.05µA), stable operation with 0402 1µF ceramic capacitors, and thermal shutdown protection across –40°C to +125°C junction range.
Technical Context
The MIC5380-PPYFT-TR integrates two CMOS-based LDOs sharing a common input (VIN) and ground (GND), each controlled by dedicated active-high enable pins (EN1, EN2). Its architecture supports independent regulation without cross-coupling, enabling asymmetric power sequencing in multi-rail subsystems.
Each LDO employs internal reference and error amplifier feedback with low-noise design (200µVRMS, 10Hz–100kHz), high PSRR (60dB @ 1kHz), and fast transient response enabled by minimal external capacitance requirements (1µF ceramic).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V per channel - eliminates external resistor networks and simplifies BOM for dual-rail 3.0V logic or analog supply. |
| Max Output Current | 150mA per LDO - sufficient to power core logic, RF transceivers, or sensor interfaces in compact handhelds. |
| Dropout Voltage | 155mV at 150mA - enables operation down to VIN = 3.155V while maintaining regulation on 3.0V rails. |
| Quiescent Current | 32µA per LDO - extends battery life in always-on monitoring functions without sacrificing startup speed. |
| Accuracy | ±1% typical over load/temperature - ensures reliable voltage margining for 3.0V I/O standards like SDIO or USB PHY. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding VIN. |
| Shutdown Current | 0.05µA - near-zero leakage during system sleep modes, critical for multi-week standby in wearables. |
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 3.0V output for LDO1 - connects directly to load requiring independent 3.0V rail. |
| 2 | VOUT2 | Regulated 3.0V output for LDO2 - electrically isolated from VOUT1 for noise-sensitive analog circuits. |
| 3 | EN2 | Active-high enable for LDO2 - logic high ≥1.2V enables regulation; floating prohibited. |
| 4 | EN1 | Active-high enable for LDO1 - allows staggered power-up or selective shutdown of individual rails. |
| 5 | GND | Common ground reference - must be low-impedance connection to minimize noise coupling between LDOs. |
| 6 | VIN | Input supply (2.5V–5.5V) - shared by both LDOs; requires 1µF ceramic decoupling capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 0402 1µF ceramics | Enables ultra-compact PCB layout using industry-standard 0402 capacitors - no larger or specialized components required. |
| Independent enable control | Permits dynamic power gating of each 3.0V rail - essential for low-power state management in portable SoC designs. |
| Thermal shutdown protection | Automatically disables both LDOs if junction temperature exceeds safe limit - prevents damage during overload or poor heatsinking. |
| Low-noise output | 200µVRMS noise (10Hz–100kHz) - suitable for powering ADC references or RF front-end bias without added filtering. |
| Current limit protection | 200–550mA per LDO - safeguards against short-circuit faults while allowing brief inrush currents during startup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D302MR-G | Single-output 3.0V LDO; 150mA; 1mm × 1mm USP-6B package; no dual-channel capability. | Requires two devices for dual-rail use - increases footprint and BOM count. | Select when only one regulated rail is needed or when higher PSRR (70dB @ 1kHz) is prioritized over integration. |
| Ricoh RP512K302D-TR-F | Dual 3.0V LDO; 200mA per channel; 1.2mm × 1.2mm DFN-8 package; 45µA quiescent current per LDO. | Larger footprint and higher IQ reduce suitability for smallest wearables. | Select when higher output current headroom or extended -40°C to +105°C ambient rating is required. |
Compared with Torex XC6216D302MR-G and Ricoh RP512K302D-TR-F, the MIC5380-PPYFT-TR uniquely delivers dual 3.0V/150mA regulation in the smallest possible footprint (1mm × 1mm) with lowest shutdown current (0.05µA), making it optimal for miniaturized battery-powered systems where space and standby power are critical constraints.

FAQ
What is the input voltage range supported by the MIC5380-PPYFT-TR?
The MIC5380-PPYFT-TR operates from 2.5V to 5.5V on its VIN pin. This range accommodates common battery sources including single-cell Li-ion (3.0–4.2V), Li-polymer, and regulated 3.3V or 5V system rails. Operation below 2.5V risks dropout or loss of regulation on either 3.0V output.
Does the MIC5380-PPYFT-TR include output discharge functionality?
No - the MIC5380-PPYFT-TR does not include auto-discharge. That feature is exclusive to the MIC5381 variant (e.g., MIC5381-PPYFT). The MIC5380-PPYFT-TR lacks the internal 30Ω NFET discharge path; external bleed resistors are required if rapid output discharge is needed during shutdown.
Can the MIC5380-PPYFT-TR be used with 0402-size 1µF ceramic capacitors?
Yes - the MIC5380-PPYFT-TR is explicitly characterized and stabilized with 0402 1µF X5R/X7R ceramic capacitors on both input and output. This eliminates need for larger footprints or higher-value capacitors, directly supporting ultra-dense PCB layouts.
What is the maximum junction temperature and thermal resistance of the MIC5380-PPYFT-TR?
The MIC5380-PPYFT-TR has a maximum junction temperature of +125°C and a junction-to-ambient thermal resistance (θJA) of 150°C/W in the standard 1mm × 1mm Thin MLF® package. At 150mA per channel and 3.6V input, calculated power dissipation is ~0.18W, limiting max ambient temperature to ~98°C under minimum footprint conditions.
How does the enable logic work on the MIC5380-PPYFT-TR?
The MIC5380-PPYFT-TR uses active-high enable inputs: EN1 controls LDO1 and EN2 controls LDO2. A logic high ≥1.2V enables the respective regulator; a logic low ≤0.2V disables it into zero-off-mode (0.05µA). Neither EN pin may float - tie unused enables to GND or VIN via pull-down/pull-up resistors to ensure deterministic behavior.
