Product details
Overview
MIC5200-3.0BS from Microchip Technology is a 3.0 V fixed-output, 100 mA low-dropout linear regulator in SOT-23-5 package with 350 mV dropout at full load, ±2% output voltage accuracy, and thermal shutdown protection. It powers microcontroller I/O rails and sensor analog front-ends in battery-powered IoT edge nodes.
For engineers reviewing the MIC5200-3.0BS datasheet, MIC5200-3.0BS pinout, MIC5200-3.0BS application, or MIC5200-3.0BS equivalent, key selection criteria include dropout voltage at 100 mA, ground current vs. load, reverse polarity protection absence, and thermal performance in SOT-23-5 under continuous 85°C ambient.
Technical Context
The MIC5200-3.0BS uses a PNP pass transistor architecture enabling stable regulation with minimal input-to-output differential. It integrates internal current limiting and thermal foldback to prevent damage during sustained overload or high ambient temperature operation.
No external compensation is required; stability is guaranteed with 1 µF ceramic output capacitor. The device operates over -40°C to +125°C junction temperature range and supports enable-controlled shutdown with <1 µA quiescent current in disable mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures consistent logic-level compatibility for 3.3 V tolerant peripherals without external feedback network. |
| Max Output Current | 100 mA - sufficient for powering single-core MCUs, digital sensors, or RF transceivers in ultra-low-power modes. |
| Dropout Voltage | 350 mV at 100 mA - enables operation from single-cell Li-ion (3.0–3.6 V) or two-cell alkaline (2.4–3.2 V) sources. |
| Ground Current | 1.3 mA at full load - minimizes total system quiescent power, critical for battery life in always-on sensing applications. |
| PSRR | 70 dB at 120 Hz - suppresses ripple from switching DC/DC stages upstream, preserving ADC reference stability. |
| Operating Temp | −40°C to +125°C - qualified for industrial and automotive under-hood environments without derating. |
Pinout & Package
SOT-23-5 surface-mount package with exposed thermal pad (not electrically connected); 1.6 mm × 2.9 mm footprint; JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control; pulls regulator into <1 µA shutdown when driven low. |
| 2 (GND) | Ground reference | Power and signal return path; connects to PCB thermal pad for enhanced heat dissipation. |
| 3 (OUT) | Regulated output | Delivers stable 3.0 V to load; requires ≥1 µF ceramic capacitor placed within 3 mm of pin. |
| 4 (IN) | Input supply | Accepts 3.3–16 V unregulated input; must be decoupled with ≥1 µF ceramic capacitor near pin. |
| 5 (GND) | Second ground terminal | Dedicated low-impedance return for internal bias circuitry; improves PSRR and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 350 mV @ 100 mA enables use with marginal input sources where higher-dropout regulators fail. |
| Thermal shutdown with foldback | Prevents catastrophic failure during sustained overload by reducing output current as die temperature exceeds 165°C. |
| No external compensation required | Guaranteed stability with 1 µF ceramic output capacitor simplifies layout and reduces BOM count. |
| Enable control with ultra-low shutdown current | <1 µA shutdown current extends battery life in intermittent-sensing applications with host MCU-controlled power gating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | Same 3.0 V output, but 250 mA rating and 170 mV dropout; SOT-23-3 (no EN pin). | Lacks enable control; unsuitable where host MCU must gate power to peripheral subsystems. | Select MCP1700T-3002E/TT only if enable functionality is unnecessary and lower dropout is prioritized. |
| NCP1117ST30T3G | 3.0 V fixed, 1 A rating, 1.2 V dropout, TO-220/SOT-223 package; no enable pin. | Higher thermal mass and larger footprint; not viable for space-constrained PCBs. | Choose NCP1117ST30T3G only when >100 mA load current or higher thermal margin is required. |
Compared with MCP1700T-3002E/TT and NCP1117ST30T3G, the MIC5200-3.0BS uniquely balances enable control, SOT-23-5 compactness, and 100 mA capability-making it optimal for battery-gated, space-limited embedded systems requiring precise 3.0 V regulation.

FAQ
What is the maximum input voltage rating for MIC5200-3.0BS?
The MIC5200-3.0BS supports an absolute maximum input voltage of 16 V. Operation above this level risks permanent damage to the internal pass transistor and protection circuitry. For designs using 12 V nominal supplies, ensure transient spikes remain below 16 V through appropriate clamping or filtering, as the MIC5200-3.0BS does not integrate overvoltage protection.
Does MIC5200-3.0BS require an external capacitor on the output pin?
Yes, the MIC5200-3.0BS requires a minimum 1 µF ceramic capacitor connected directly to the OUT pin for stability. This capacitor must be placed within 3 mm of the pin with low-inductance routing. Using tantalum or electrolytic capacitors is not recommended due to ESR and aging effects that may compromise transient response and loop stability.
Can MIC5200-3.0BS be used without connecting the EN pin?
Yes, MIC5200-3.0BS operates continuously when the EN pin is left unconnected or tied to IN. Internal pull-up ensures default-enable behavior. However, for lowest quiescent current in standby, connect EN to GND via MCU GPIO to achieve <1 µA shutdown current-critical for battery longevity in duty-cycled systems.
Is MIC5200-3.0BS compatible with ceramic capacitors having X7R dielectric?
Yes, MIC5200-3.0BS is fully compatible with X7R ceramic capacitors rated ≥1 µF and ≥6.3 V. X7R offers stable capacitance over temperature and DC bias, meeting the stability and ESR requirements specified in the MIC5200-3.0BS datasheet. Avoid Y5V or Z5U types due to excessive capacitance loss at bias and temperature extremes.
What thermal derating applies to MIC5200-3.0BS in SOT-23-5 package at 85°C ambient?
At 85°C ambient, the MIC5200-3.0BS delivers full 100 mA output only with ≤25°C/W PCB thermal resistance to ambient. With standard 2-layer FR-4 (no thermal pad), output current must be limited to ~65 mA to maintain junction temperature ≤125°C. Use of the exposed thermal pad and copper pour significantly improves thermal performance.
