Product details
Overview
MIC5206-3.6YM5-TR from Micrel is a 150mA, 3.6V fixed-output low-dropout linear regulator in SOT-23-5 package, featuring 165mV dropout at full load, 600µA ground current at 100mA, and ±1% initial output voltage accuracy. It integrates CMOS/TTL-compatible enable control, open-collector error flag for undervoltage detection, and reversed-battery protection - optimized for battery-powered handheld devices requiring stable, ultra-low-noise power.
For engineers reviewing the MIC5206-3.6YM5-TR datasheet, MIC5206-3.6YM5-TR pinout, MIC5206-3.6YM5-TR application, or MIC5206-3.6YM5-TR equivalent, key selection criteria include dropout performance at 150mA, enable logic thresholds (VIL ≤ 0.4V, VIH ≥ 2.0V), FLAG output behavior under undervoltage, thermal resistance (θJA = 220°C/W), and compatibility with ceramic or tantalum output capacitors ≥1.0µF.
Technical Context
The MIC5206-3.6YM5-TR uses a PNP pass transistor architecture enabling ultra-low dropout (17mV typical at light load) and minimal ground current variation across load. Its internal undervoltage monitor triggers the open-collector FLAG pin when output falls >5% below nominal - with 3% hysteresis to prevent chatter during brownout recovery.
Unlike standard LDOs, it supports true zero-current shutdown (≤5µA off-mode current) and includes reversed-battery protection without external components. The SOT-23-5 pinout omits reference bypass (BYP), distinguishing it from 8-pin MSOP variants - confirming noise performance relies on external output capacitor selection rather than internal reference filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6V ±1% initial accuracy - ensures precise biasing for 3.3V/3.6V logic rails and analog circuitry without trimming. |
| Max Output Current | 150mA guaranteed - supports moderate-power peripherals like RF front-ends, sensors, or microcontroller I/O banks. |
| Dropout Voltage | 165mV at 150mA - enables regulation from 3.76V input (e.g., single Li-ion cell at end-of-discharge) while maintaining 3.6V output. |
| Ground Current | 600µA at 100mA load - minimizes quiescent loss in always-on subsystems such as real-time clocks or keep-alive memory. |
| Enable Thresholds | VIL ≤ 0.4V (shutdown), VIH ≥ 2.0V (enable) - compatible with 3.3V and 5V logic families without level-shifting. |
| FLAG Response | Open-collector output active low at –5% VOUT - provides direct interface to µC interrupt pins or supervisor ICs for fault logging. |
| Thermal Resistance | θJA = 220°C/W (SOT-23-5, FR4) - limits max power dissipation to ~380mW at 40°C ambient before thermal shutdown. |
Pinout & Package
SOT-23-5 surface-mount package with 1.3mm × 2.9mm footprint, 0.95mm height, and gull-wing leads - designed for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts 2.5V–16V input; requires ≥1µF ceramic capacitor to GND if >10" trace length or battery source. |
| 2 (GND) | Ground Reference | Common return path for load, enable, and flag circuits; must connect to low-impedance ground plane. |
| 3 (EN) | Enable/Shutdown Input | CMOS/TTL-compatible control: high ≥2.0V enables regulator; low ≤0.4V disables with <5µA quiescent draw. |
| 4 (FLAG) | Error Flag Output | Open-collector undervoltage indicator - requires external pull-up (e.g., 47kΩ to IN) to generate logic-level signal. |
| 5 (OUT) | Regulated Output | Delivers 3.6V ±1% to load; requires ≥1.0µF output capacitor (ceramic/tantalum, ESR ≤5Ω) for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 17mV typical at light loads - extends usable battery life by regulating down to near-VOUT input voltage. |
| Logic-controlled shutdown | Sub-5µA off-state current - eliminates parasitic drain in sleep modes of portable electronics. |
| Integrated undervoltage monitor | –5% VOUT threshold with 3% hysteresis - prevents system malfunction by signaling supply collapse before critical logic failure. |
| Reversed-battery protection | No external diode required - blocks reverse polarity up to –20V, protecting downstream circuitry during battery insertion errors. |
| Tight line/load regulation | ±0.05% line reg, ±0.1% load reg - maintains output stability despite input ripple or dynamic load changes in SMPS post-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3602E/MB | 150mA output, 600mV dropout at full load, 1.6µA quiescent current - higher dropout, lower IQ. | Lacks error flag and reversed-battery protection - requires external supervision circuitry for fault detection. | Choose when ultra-low IQ dominates over dropout and protection features. |
| TPS76336DBVR | 150mA output, 250mV dropout at full load, 85µA quiescent current - includes power-good flag but no reversed-battery protection. | Higher dropout limits use with single-cell Li-ion below 3.85V; PG flag lacks hysteresis. | Prefer when TI ecosystem integration or tighter thermal specs (θJA = 209°C/W) are prioritized over battery-protection robustness. |
Compared with MCP1700T-3602E/MB and TPS76336DBVR, the MIC5206-3.6YM5-TR delivers superior dropout performance (165mV vs. ≥250mV), integrated reversed-battery protection, and a hysteresis-equipped FLAG output - making it uniquely suited for cost-sensitive, battery-critical handheld designs where input polarity errors and deep discharge operation must be handled autonomously.

FAQ
What is the minimum input voltage required for MIC5206-3.6YM5-TR to maintain regulation?
The MIC5206-3.6YM5-TR requires an input voltage at least 165mV above its 3.6V output to sustain 150mA load - i.e., VIN ≥ 3.765V. At lighter loads, dropout drops to 17mV (VIN ≥ 3.617V). Operation below these thresholds causes output collapse; absolute minimum VIN is 2.5V per datasheet operating ratings.
Does MIC5206-3.6YM5-TR require an external bypass capacitor on the BYP pin?
No - the MIC5206-3.6YM5-TR is the SOT-23-5 fixed-voltage variant and does not include a BYP pin. Reference bypass functionality is exclusive to the 8-pin MSOP (MM) versions. Noise reduction for MIC5206-3.6YM5-TR relies solely on proper selection of output capacitor (≥1.0µF, ESR ≤5Ω).
How does the FLAG pin behave during enable/disable transitions in MIC5206-3.6YM5-TR?
The FLAG pin is an open-collector output that goes low when output voltage drops >5% below 3.6V. During enable, FLAG remains high until output stabilizes; during disable, FLAG floats high (requires external pull-up). To avoid indeterminate states, EN fall time must be <100µs - ensuring FLAG deasserts cleanly before output collapses.
Can MIC5206-3.6YM5-TR be used with ceramic output capacitors?
Yes - the MIC5206-3.6YM5-TR is stable with ceramic output capacitors ≥1.0µF (no BYP pin). Unlike older LDOs, it does not require ESR-based damping; low-ESR ceramics improve transient response and reduce board area versus tantalum alternatives.
What thermal derating applies to MIC5206-3.6YM5-TR at 60°C ambient temperature?
With θJA = 220°C/W, the MIC5206-3.6YM5-TR's maximum allowable power dissipation at 60°C ambient is PD(max) = (125°C − 60°C) / 220°C/W ≈ 295mW. At 3.6V output and 150mA load, power dissipation is (VIN − 3.6V) × 0.15A - so VIN must stay ≤ 5.57V to remain within thermal limits.
