Product details
Overview
MIC5304-XGHYMT-TR from Micrel is a single-channel 150mA low-dropout linear regulator with dual fixed output voltage selection (3.15V/1.875V) controlled by a logic-level VSEL pin, ultra-low 24µA quiescent current, 85mV dropout at 150mA, and operation across 2.3V–5.5V input range - designed for power-constrained portable electronics requiring dynamic voltage scaling.
For engineers reviewing the MIC5304-XGHYMT-TR datasheet, MIC5304-XGHYMT-TR pinout, MIC5304-XGHYMT-TR application, or MIC5304-XGHYMT-TR equivalent, key selection criteria include dual-voltage LDO functionality, thermal shutdown and current limit protection, compatibility with 1µF ceramic input/output capacitors, and operation in the 1.6mm × 1.6mm Thin MLF® package with exposed thermal pad.
Technical Context
The MIC5304-XGHYMT-TR integrates an internal resistor divider network and precision bandgap reference to support two factory-trimmed output voltages selected via TTL-compatible VSEL logic. Its CMOS-based control circuitry enables fast 35–100µs transition between output states while maintaining stable regulation under load steps up to 150mA.
It features active-high enable (EN) with <1µA shutdown current, ground pin current tightly regulated from 24µA to 35µA across load, and ripple rejection of 65dB at 1kHz (VSEL=High) and 50dB at 20kHz - optimized for noise-sensitive RF and memory subsystems in battery-powered devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 150mA max - supports core logic and I/O rails in compact portable devices without external heat sinking. |
| Quiescent Current | 24µA typ - extends battery life in standby/sleep modes of mobile phones and PMPs. |
| Dropout Voltage | 85mV @ 150mA - enables efficient regulation from 3.3V or 3.6V batteries down to 3.15V/1.875V outputs. |
| Input Voltage Range | 2.3V to 5.5V - compatible with Li-ion, Li-poly, and dual-cell alkaline supplies. |
| Output Voltage Options | 3.15V (VSEL=High) / 1.875V (VSEL=Low) - factory-trimmed for precise dual-rail memory or processor I/O voltage selection. |
| Capacitor Requirement | Stable with ≥1µF ceramic (X5R/X7R) - eliminates need for bulky tantalum or electrolytic capacitors. |
| Protection Features | Thermal shutdown + current limit (275–750mA) - prevents damage during short-circuit or overload conditions. |
Pinout & Package
Package: 6-pin 1.6mm × 1.6mm Thin MLF® (MT) with exposed thermal pad (E PAD) internally connected to GND - optimized for minimal PCB area and enhanced thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Supply Input | Accepts 2.3V–5.5V unregulated input; requires 1µF ceramic bypass to GND. |
| 2 - GND | Ground Reference | Primary return path for load and quiescent current; connects to E PAD for thermal conduction. |
| 3 - VSEL | Voltage Select Control | TTL-compatible input: HIGH → 3.15V output, LOW → 1.875V output; must not float. |
| 4 - EN | Enable Input | Active-high logic control: HIGH → regulator active, LOW → zero-off mode (<1µA IQ). |
| 5 - NC | No Connect | Not internally bonded - leave unconnected; no routing or soldering required. |
| 6 - VOUT | Regulated Output | Delivers stable 3.15V or 1.875V depending on VSEL state; requires 1µF ceramic capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed-output voltage selection | Hardware-selectable 3.15V/1.875V outputs enable dynamic power rail switching for memory cards and low-power I/O without software intervention. |
| Ultra-low quiescent current | 24µA typical operating current minimizes battery drain in always-on or sleep-mode applications such as PNDs and digital cameras. |
| Fast voltage transition | 35–100µs output settling time between voltage states ensures rapid response to system-level power mode changes. |
| Small-footprint stability | Guaranteed stability with 1µF X5R/X7R ceramic capacitors reduces BOM count and board area versus legacy LDOs requiring >10µF. |
| Integrated protection | Thermal shutdown and foldback current limiting prevent permanent damage during sustained overloads or PCB thermal violations. |
Applications
| Mobile Memory Card Power | Dual-Rail Processor I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5304-RGYMT | Fixed 3.2V/1.8V output pair; same package, pinout, and electrical specs except nominal voltages. | Used where 3.2V/1.8V matches target memory or interface standard more closely than 3.15V/1.875V. | Select RGYMT when exact 3.2V/1.8V compliance is required for JEDEC or SD card timing margins. |
| MIC5304-XDYMT | Fixed 3.15V/1.85V output pair; identical thermal, transient, and capacitor requirements. | Preferred for systems needing tighter 1.85V tolerance on low-voltage rail, e.g., certain LPDDR I/O interfaces. | Choose XDYMT when 1.85V aligns better with SoC I/O VDDQ spec than 1.875V, especially in high-speed memory subsystems. |
Compared with MIC5304-RGYMT and MIC5304-XDYMT, the MIC5304-XGHYMT-TR provides a unique 3.15V/1.875V combination optimized for newer low-voltage memory controllers and energy-efficient sensor interfaces - offering finer granularity in low-power mode tuning without changing layout or bill-of-materials.

FAQ
What output voltages does the MIC5304-XGHYMT-TR support?
The MIC5304-XGHYMT-TR supports two factory-trimmed output voltages: 3.15V when the VSEL pin is driven HIGH, and 1.875V when VSEL is driven LOW. These values are specified across –40°C to +125°C and are guaranteed by Micrel's production test flow - not typical-only values. The MIC5304-XGHYMT-TR does not support adjustable or additional voltage options outside this pair.
Can the MIC5304-XGHYMT-TR operate with input voltage below 2.3V?
No. The MIC5304-XGHYMT-TR has a minimum specified input voltage of 2.3V per its Absolute Maximum and Operating Ratings. Operation below this threshold may result in loss of regulation, unpredictable VSEL/EN behavior, or failure to maintain output accuracy. The MIC5304-XGHYMT-TR requires VIN ≥ 2.3V to guarantee all electrical characteristics including dropout, load regulation, and transition time.
Is an external capacitor required on the EN pin of the MIC5304-XGHYMT-TR?
No external capacitor is required or recommended on the EN pin of the MIC5304-XGHYMT-TR. The EN input is CMOS-based with leakage <1µA and no AC sensitivity; it must be driven directly by a logic signal or pulled to GND/VIN via a resistor. Adding capacitance risks violating the 150–500µs turn-on time spec and may cause erratic startup behavior. The MIC5304-XGHYMT-TR datasheet specifies direct connection only.
Does the MIC5304-XGHYMT-TR require a specific capacitor dielectric type?
Yes. The MIC5304-XGHYMT-TR is characterized and guaranteed stable with X5R or X7R ceramic capacitors (1µF, 6.3V rating). Y5V and Z5U dielectrics are explicitly discouraged due to >50% capacitance loss over temperature, which risks instability. The MIC5304-XGHYMT-TR's stability margin assumes ±15% capacitance variation - met only by X7R - and deviating voids the 1µF minimum guarantee.
How is thermal performance affected by the exposed pad on the MIC5304-XGHYMT-TR?
The exposed thermal pad (E PAD) on the MIC5304-XGHYMT-TR is internally connected to GND and must be soldered to a dedicated PCB copper pour for effective heat dissipation. With proper pad layout, θJA drops from 92°C/W (minimum footprint) to ~65°C/W, enabling full 150mA output at ambient temperatures up to 100°C. Omitting E PAD connection degrades thermal performance and risks premature thermal shutdown - the MIC5304-XGHYMT-TR relies on this pad for safe continuous operation.
