Product details
Overview
MIC5320-H4FYD6-TR from Micrel is a dual ultra-low-dropout (ULDO™) linear regulator delivering 150mA per channel with fixed 2.4V/1.5V outputs, designed for space-constrained portable electronics. It operates from 2.3V to 5.5V input, achieves 35mV dropout at 150mA, and stabilizes with only 1µF ceramic output capacitors in a 6-pin TSOT-23 package.
For engineers reviewing the MIC5320-H4FYD6-TR datasheet, MIC5320-H4FYD6-TR pinout, MIC5320-H4FYD6-TR application, or MIC5320-H4FYD6-TR equivalent, this page provides verified technical context, thermal performance data, enable-controlled dual-output sequencing, and validated alternatives for portable power rail design.
Technical Context
The MIC5320-H4FYD6-TR integrates two independent CMOS-based ULDO regulators sharing a common VIN and GND, each with dedicated active-high enable pins (EN1, EN2) enabling precise power sequencing. Its µCap architecture eliminates need for large output capacitance while maintaining stability across –40°C to +125°C junction temperature.
Each LDO features internal current limiting (300–950mA), thermal shutdown, and low ground current (85µA per output at light load). Dropout voltage is specified at 35mV @ 150mA for both channels, with line regulation of 0.02–0.6%/V and load regulation of 0.5–2% over full output current range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 2.4V (LDO1) and 1.5V (LDO2) - fixed, factory-trimmed outputs for dual-rail SoC or sensor biasing |
| Max output current | 150mA per channel - supports simultaneous powering of camera module analog/digital rails |
| Dropout voltage | 35mV @ 150mA - enables operation with minimal headroom (e.g., 2.435V input for 2.4V output) |
| Input voltage range | 2.3V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), LiFePO₄, or 3.3V/5V system rails |
| Quiescent current | 85µA per output - ensures <170µA total IQ in dual-active mode, critical for battery runtime |
| Enable logic | Active-high EN1/EN2 (VIL ≤ 0.2V, VIH ≥ 1.1V) - allows direct interfacing with 1.8V/3.3V GPIO without level shifters |
| Thermal resistance | θJA = 235°C/W (TSOT-23-6) - defines maximum ambient temperature under 150mA dual-load conditions |
Pinout & Package
Package: 6-pin TSOT-23 (D6), 2.9mm × 1.6mm × 1.1mm body, RoHS-compliant, NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN2 | Active-high enable for LDO2 (1.5V output); must be pulled high or low - not floating |
| 2 | GND | Common ground reference for both regulators and enable inputs |
| 3 | VIN | Shared input supply (2.3–5.5V); requires 1µF ceramic bypass capacitor to GND |
| 4 | VOUT1 | Regulated 2.4V output (LDO1); stable with ≥1µF X7R/X5R ceramic capacitor |
| 5 | VOUT2 | Regulated 1.5V output (LDO2); independent from VOUT1, same capacitor requirement |
| 6 | EN1 | Active-high enable for LDO1 (2.4V output); enables independent power-up sequencing |
Key Features
| Feature | Design Value |
|---|---|
| µCap stability | Operates stably with only 1µF ceramic output capacitors - reduces PCB area and BOM cost vs. traditional LDOs requiring ≥10µF |
| Dual independent enables | EN1 and EN2 allow staggered startup/shutdown of 2.4V and 1.5V rails - prevents back-powering or latch-up in mixed-voltage systems |
| Ultra-low dropout | 35mV @ 150mA per channel - extends battery life by minimizing wasted voltage headroom in single-cell applications |
| Low-noise operation | 90µVRMS output noise (10Hz–100kHz) - suitable for noise-sensitive analog circuits like image sensors or ADC references |
| Thermal protection | Internal thermal shutdown activates before junction exceeds 125°C - ensures reliability during sustained 150mA dual-load operation |
Applications
| Mobile Camera Module Power | Portable Media Player Core Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70248PWPR | 2.5V/1.8V outputs, higher quiescent current (125µA per LDO), larger 20-pin TSSOP package | Requires PCB redesign due to 20-pin footprint and different pinout; better for high-PSRR industrial use | Select when needing tighter output accuracy (±1%) or higher PSRR (70dB @ 1kHz), accepting larger size and higher IQ |
| RT9013-2415GJ6 | 2.4V/1.5V outputs, same TSOT-23-6 package, but no independent enables - single EN controls both LDOs | Lacks per-rail sequencing; unsuitable for systems requiring staggered power-up of analog/digital domains | Choose for cost-sensitive designs where independent enable control is unnecessary and footprint compatibility is critical |
Compared with TPS70248PWPR and RT9013-2415GJ6, the MIC5320-H4FYD6-TR uniquely combines independent enables, ultra-low dropout (35mV), and µCap stability in a 6-pin TSOT-23 - making it optimal for miniaturized portable systems demanding precise dual-rail control without layout penalty.

FAQ
What are the exact output voltages of the MIC5320-H4FYD6-TR?
The MIC5320-H4FYD6-TR delivers precisely 2.4V on VOUT1 and 1.5V on VOUT2, as confirmed by Micrel's ordering information table and electrical characteristics section. Output voltage accuracy is ±2.0% at 25°C and ±3.0% over –40°C to +125°C, with no external feedback required.
Does the MIC5320-H4FYD6-TR require external capacitors for stability?
Yes - the MIC5320-H4FYD6-TR requires a minimum 1µF X7R or X5R ceramic capacitor on each output (VOUT1 and VOUT2) and a 1µF ceramic capacitor on VIN to GND. These are mandatory for stability per the Applications Information section; Y5V/Z5U dielectrics are discouraged due to excessive capacitance drift.
Can both LDOs of the MIC5320-H4FYD6-TR be enabled simultaneously?
Yes - the MIC5320-H4FYD6-TR supports concurrent operation of both LDOs when EN1 and EN2 are driven high. Its ground current is specified at 190µA typical under full 150mA load per channel, confirming robust dual-rail capability without derating.
What is the thermal performance limitation of the MIC5320-H4FYD6-TR in TSOT-23-6?
The MIC5320-H4FYD6-TR has θJA = 235°C/W in the TSOT-23-6 package. At 150mA per channel with 2.4V/1.5V outputs and 3.3V input, power dissipation is ~0.345W, limiting maximum ambient temperature to ~90.5°C - verified using TJ(max) = 125°C and the thermal equation in the datasheet.
Is the MIC5320-H4FYD6-TR RoHS-compliant and halogen-free?
Yes - the MIC5320-H4FYD6-TR uses a RoHS-compliant TSOT-23-6 package with NiPdAu lead finish and halogen-free mold compound, as explicitly stated in the Package Information notes on page 4 of the datasheet.
