Product details
Overview
MIC5306-2.6YD5 from Microchip Technology is a fixed-output 2.6V, 150 mA micropower low-dropout linear regulator in a 5-lead TSOT-23 package. It delivers ±1.0% initial output accuracy, 45 mV dropout at 100 mA, and draws only 16 μA quiescent current-enabling long battery life in portable baseband power rails.
For engineers reviewing the MIC5306-2.6YD5 datasheet, MIC5306-2.6YD5 pinout, MIC5306-2.6YD5 application, or MIC5306-2.6YD5 equivalent, this page provides verified specifications, thermal behavior, enable logic compatibility, ceramic-capacitor stability, and real-world load transient response data for low-power embedded system design.
Technical Context
The MIC5306-2.6YD5 uses a CMOS-based pass element with internal reference and error amplifier to regulate output voltage under varying input (2.25–5.5 V) and load (0–150 mA) conditions. Its μCap architecture ensures stability with ≥1 μF ceramic output capacitors and achieves 62 dB PSRR at 10 Hz–1 kHz.
It integrates TTL/CMOS-compatible active-high enable (EN), thermal shutdown (150°C trip), and current limit (~285 mA typical). Ground current remains stable across temperature (–40°C to +125°C) and load, supporting predictable power budgeting in battery-constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6 V ±1.0% (initial), ±2.0% over –40°C to +125°C - ensures reliable logic-level supply for baseband ICs. |
| Max Output Current | 150 mA continuous - sufficient for powering RF transceivers, microcontrollers, or sensor interfaces in compact devices. |
| Dropout Voltage | 45 mV @ 100 mA - enables operation from single-cell Li-ion (3.0 V min) or dual-cell alkaline with minimal headroom loss. |
| Quiescent Current | 16 μA operating / 0.01 μA shutdown - extends shelf life and runtime in always-on standby circuits. |
| PSRR | 62 dB @ 10 Hz–1 kHz - suppresses ripple from noisy DC-DC converters feeding the LDO input. |
| Enable Threshold | VIH ≥ 1.0 V, VIL ≤ 0.2 V - compatible with 1.8 V/3.3 V GPIO without level-shifting. |
| Thermal Shutdown | 150°C with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal layout. |
Pinout & Package
Package: 5-Lead Thin Small Outline Transistor (TSOT-23-5), 1.6 mm × 1.6 mm × 0.55 mm body, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Supply input | Accepts 2.25–5.5 V input; requires 1 μF bypass capacitor to GND for stability and noise rejection. |
| GND (Pin 2) | Ground reference | Low-impedance return path for load and quiescent current; must be connected directly to PCB ground plane. |
| EN (Pin 3) | Enable control | Active-high logic input; drives regulator ON when ≥1.0 V, OFF when ≤0.2 V; do not leave floating. |
| NC (Pin 4) | No connect | Internally unconnected; must remain unconnected on PCB to avoid parasitic coupling or reliability risk. |
| OUT (Pin 5) | Regulated output | Delivers stable 2.6 V to load; requires ≥1 μF ceramic capacitor (ESR < 300 mΩ) between OUT and GND. |
Key Features
| Feature | Design Value |
|---|---|
| μCap ceramic-stable operation | Stable with ≥1 μF X5R/X7R ceramic capacitors - eliminates bulkier tantalum/electrolytic parts and reduces board area by >50%. |
| Zero-off-mode shutdown | 0.01 μA shutdown current - enables true "off" state for energy harvesting or ultra-low-power wake-on-event designs. |
| Fast transient response | <500 μs turn-on time and damped load-step recovery - maintains voltage integrity during burst-mode processor activity. |
| Integrated protection | Current limit (~285 mA) + thermal shutdown (150°C) - eliminates need for external foldback or thermal sensors in space-constrained layouts. |
| High accuracy over temperature | ±2.0% output tolerance across –40°C to +125°C - supports industrial-grade operation without calibration. |
Applications
| Mobile Baseband Power | Standby Rail for IoT Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2602E/TO | Same 2.6 V output, but 250 mA max current and 1.8 μA IQ - lower IQ but higher dropout (115 mV @ 100 mA). | Better for ultra-low-IQ sleep modes; less suitable for high-transient 150 mA loads due to slower response and higher dropout. | Choose MCP1700-2602E/TO only if standby current is prioritized over dynamic performance and thermal headroom. |
| Torex XC6206P262MR-G | 2.6 V, 150 mA, 12 μA IQ, but no enable pin and ±2% accuracy - lacks shutdown control and tighter initial tolerance. | Applicable where always-on operation is acceptable and enable sequencing is handled externally or not required. | Select XC6206P262MR-G only when board space permits omitting EN routing and system-level accuracy requirements allow ±2%. |
Compared with MCP1700-2602E/TO and XC6206P262MR-G, the MIC5306-2.6YD5 uniquely balances low IQ (16 μA), tight accuracy (±1%), fast enable response (250–500 μs), and integrated protection - making it optimal for space-constrained, battery-operated systems requiring both precision and controllability.

FAQ
What is the maximum input voltage rating for the MIC5306-2.6YD5?
The MIC5306-2.6YD5 has an absolute maximum input voltage rating of +6 V. However, its specified operating input range is +2.25 V to +5.5 V. Exceeding 5.5 V may cause functional instability or accelerated degradation, even if below the 6 V absolute limit. Always operate within the 2.25–5.5 V range for guaranteed performance and reliability of the MIC5306-2.6YD5.
Does the MIC5306-2.6YD5 require an input capacitor, and if so, what value is recommended?
Yes, the MIC5306-2.6YD5 requires a 1 μF ceramic capacitor from VIN to GND when more than 10 inches of wire separates the input source from the AC filter capacitor or when powered directly from a battery. This capacitor stabilizes the input impedance and improves line transient response. The MIC5306-2.6YD5 datasheet explicitly specifies this value and type to ensure robust operation under dynamic load conditions.
Can the MIC5306-2.6YD5 be used without connecting the EN pin?
No - the EN pin (Pin 3) must not be left floating. If enable functionality is unused, the MIC5306-2.6YD5 datasheet mandates connecting EN directly to VIN to ensure the regulator remains enabled. Leaving EN unconnected risks unpredictable behavior, including intermittent shutdown or increased noise susceptibility. This requirement applies strictly to the MIC5306-2.6YD5 and is confirmed in Section 4.3 of the official datasheet.
What is the thermal resistance (θJA) of the MIC5306-2.6YD5 in its TSOT-23-5 package?
The MIC5306-2.6YD5 in the 5-Lead TSOT-23 package has a junction-to-ambient thermal resistance (θJA) of 235°C/W under the recommended minimum footprint layout. This value is measured per JEDEC standards and is used to calculate maximum ambient temperature under load. For example, at 150 mA and 1.0 V dropout, power dissipation is ~0.15 W, limiting max ambient to ~89.8°C - a key design constraint for the MIC5306-2.6YD5 in enclosed environments.
Is the NC pin (Pin 4) on the MIC5306-2.6YD5 safe to connect to ground or other signals?
No - Pin 4 is designated NC (No Connect) and is internally unconnected. Connecting it to ground, VIN, or any other node violates the MIC5306-2.6YD5's validated layout and may introduce parasitic coupling, degrade PSRR, or compromise long-term reliability. The datasheet explicitly states that NC pins must remain unconnected on the PCB, and this applies without exception to the MIC5306-2.6YD5.
