Product details
Overview
MIC5320-JJYD6-TR from Micrel is a dual ultra-low-dropout (ULDO™) linear regulator delivering two independent 2.5V outputs at up to 150mA each, designed for space-constrained portable electronics. It operates from 2.3V to 5.5V input, achieves 35mV dropout at full load, and stabilizes with only 1µF ceramic output capacitors. Its TSOT-23-6 package enables compact power management in mobile phones and camera modules.
For engineers reviewing the MIC5320-JJYD6-TR datasheet, MIC5320-JJYD6-TR pinout, MIC5320-JJYD6-TR application, or MIC5320-JJYD6-TR equivalent, this page delivers verified specifications, thermal performance data, enable control behavior, µCap stability validation, and real-world dual-rail use cases in imaging and handheld systems.
Technical Context
The MIC5320-JJYD6-TR integrates two independent CMOS-based ULDO regulators sharing a common VIN and GND, each with dedicated active-high enable pins (EN1/EN2) and separate VOUT1/VOUT2 outputs. 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 channel at light load). Dropout voltage remains ≤35mV at 150mA, enabling efficient operation even with tight input–output margins typical in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V / 2.5V - Dual fixed outputs suitable for powering core logic and I/O rails simultaneously without external feedback. |
| Max Output Current | 150mA per channel - Supports moderate-power sensors, memory, and interface ICs in portable designs. |
| Dropout Voltage | 35mV @ 150mA - Enables >98% efficiency at 2.5V output with 2.535V minimum input, critical for Li-ion battery discharge tail-end operation. |
| Input Voltage Range | 2.3V to 5.5V - Compatible with single-cell Li-ion (2.7–4.2V), LiFePO₄ (2.0–3.6V), and 3.3V/5V system rails. |
| Ground Current | 85µA per enabled output - Minimizes quiescent power draw during standby, extending battery life in always-on subsystems. |
| Stability Capacitor | 1µF ceramic - Reduces BOM count and PCB area vs. traditional LDOs requiring ≥10µF tantalum or aluminum electrolytic. |
| Enable Logic | Active-high CMOS inputs (VIH ≥ 1.1V, VIL ≤ 0.2V) - Direct interfacing with 1.8V/2.5V/3.3V GPIO without level-shifting. |
| Thermal Resistance | θJA = 235°C/W (TSOT-23-6) - Requires careful layout and thermal relief for sustained 150mA operation above 60°C ambient. |
Pinout & Package
Package: TSOT-23-6 - 6-pin thin small-outline transistor package with 0.95mm pitch, 2.9mm × 1.6mm footprint, and exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN2 | Active-high enable for second LDO; must be pulled high (>1.1V) to activate VOUT2; floating prohibited. |
| 2 | GND | Common ground reference for both regulators and enable inputs; connects internally to exposed thermal pad. |
| 3 | VIN | Shared input supply rail; accepts 2.3V–5.5V; requires 1µF ceramic bypass capacitor to GND. |
| 4 | VOUT1 | First regulated output (2.5V); capable of sourcing up to 150mA with <2% initial accuracy and ±3% over temperature. |
| 5 | VOUT2 | Second regulated output (2.5V); electrically isolated from VOUT1 but shares VIN/GND; same performance specs as VOUT1. |
| 6 | EN1 | Active-high enable for first LDO; independent control allows staggered power-up or selective rail shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| µCap stability | Stable with 1µF ceramic output capacitors - eliminates need for larger, higher-ESR capacitors and reduces board area by >50% vs. legacy LDOs. |
| Independent enable control | Dual active-high EN pins (EN1/EN2) - Enables flexible power sequencing, dynamic rail disabling, and zero-quiescent-current shutdown (<2µA total). |
| Ultra-low dropout | 35mV @ 150mA - Maintains regulation down to 2.535V input at 2.5V output, maximizing usable battery capacity in single-cell systems. |
| Fast turn-on time | 30µs typical - Supports rapid power-up of peripherals in wake-from-sleep scenarios without timing violations. |
| Thermal & current protection | Integrated thermal shutdown and current limit (300–950mA) - Prevents damage during overload or poor heatsinking conditions. |
| Low-noise operation | 90µVRMS (10Hz–100kHz) - Suitable for noise-sensitive analog circuits like image sensors and ADC references. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826S-2502502D/DB | 2.5V/2.5V dual LDO in SOT-23-6; 300mA per channel; 250mV dropout @ 300mA; 120µA quiescent current. | Higher current capability but larger dropout limits battery efficiency below 2.75V input; no µCap optimization - requires ≥4.7µF output caps. | Select when higher output current is required and board space allows larger capacitors; avoid where low-input-voltage efficiency is critical. |

FAQ
What is the maximum input voltage rating for MIC5320-JJYD6-TR?
The absolute maximum input voltage for MIC5320-JJYD6-TR is +6V, but the recommended operating range is +2.3V to +5.5V. Exceeding 5.5V may trigger internal protection or cause permanent damage. The device is commonly used with single-cell Li-ion (up to 4.2V) or 3.3V/5V system rails, and its 2.3V minimum enables operation deep into battery discharge cycles.
Does MIC5320-JJYD6-TR require external compensation components?
No, MIC5320-JJYD6-TR does not require external compensation. It is µCap-stable and fully operational with only a 1µF ceramic output capacitor per channel and a 1µF ceramic input capacitor. This eliminates the need for series resistors, feedforward capacitors, or complex RC networks required by many traditional LDOs-simplifying design and reducing bill-of-materials cost.
Can MIC5320-JJYD6-TR operate with zero load on either output?
Yes, MIC5320-JJYD6-TR remains stable and in regulation with no load on either VOUT1 or VOUT2. This "no-load stability" is explicitly validated in the datasheet and is essential for applications like CMOS RAM keep-alive circuits or standby rails where one output may be idle while the other powers active circuitry.
What is the thermal performance of MIC5320-JJYD6-TR in TSOT-23-6 package?
MIC5320-JJYD6-TR has a junction-to-ambient thermal resistance (θJA) of 235°C/W in the TSOT-23-6 package. At full 150mA load on both outputs with 2.5V output and 3.3V input, power dissipation is ~0.24W, resulting in ~56°C junction rise above ambient. Adequate copper pour and thermal vias under the exposed pad are strongly recommended to maintain safe operation below 125°C junction temperature.
How does the enable functionality work on MIC5320-JJYD6-TR?
MIC5320-JJYD6-TR features two independent active-high enable inputs: EN1 controls VOUT1 and EN2 controls VOUT2. A logic high ≥1.1V enables the respective LDO; a logic low ≤0.2V disables it, reducing ground current to <2µA. Neither enable pin may be left floating-it must be actively driven or pulled to GND/VIN via a resistor to prevent indeterminate output states.
