Product details
Overview
MIC5202-5.0YM from Microchip Technology is a dual 100 mA low-dropout linear voltage regulator in an 8-pin SOIC package, delivering fixed 5.0 V outputs with ±1% accuracy, 17 mV dropout at light load, and independent active-high enable pins (EN1/EN2). It supports battery-powered systems requiring dual-rail regulation with reverse-battery protection and thermal shutdown.
For engineers reviewing the MIC5202-5.0YM datasheet, MIC5202-5.0YM pinout, MIC5202-5.0YM application, or MIC5202-5.0YM equivalent, this page provides verified electrical specs, dual-LDO timing behavior, SOIC-8 terminal mapping, and validated alternatives for portable power management designs.
Technical Context
The MIC5202-5.0YM integrates two independent LDO regulators sharing no internal bias paths-each with dedicated VIN, VOUT, GND, and EN pins. Its architecture enables true per-regulator shutdown, zero-off mode current (<0.01 µA), and dropout performance scaling from 17 mV (100 µA) to 225 mV (100 mA).
It features reversed-battery protection on both inputs, current-limiting (280 mA short-circuit), and thermal regulation (0.05 %/W), with ground current rising only slightly in dropout-preserving battery life during low-VIN operation across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V per channel, ±1% initial accuracy ensures stable logic supply for microcontrollers and peripherals without external feedback. |
| Dropout Voltage | 17 mV at 100 µA; 225 mV at 100 mA-enables regulation from 5.225 V input at full load, critical for Li-ion or multi-cell battery systems. |
| Ground Current | 1.2 mA typical at 100 mA output; drops to 0.01 µA in shutdown-minimizes quiescent drain in always-on subsystems. |
| PSRR | 75 dB-suppresses switching noise from upstream DC-DC converters, supporting clean analog or RF supply rails. |
| Operating Input Range | +2.5 V to +26 V-supports wide-input industrial and automotive post-regulation applications beyond standard 5 V supplies. |
| Enable Threshold | EN high = ≥2.0 V; EN low = ≤0.7 V-compatible with 1.8 V, 3.3 V, and 5 V logic families without level-shifting. |
| Thermal Shutdown | Activates at ~150°C junction temperature-protects against sustained overload or poor PCB thermal design. |
Pinout & Package
Package: 8-pin SOIC (M), surface-mount, Pb-free, JEDEC-compliant outline with exposed pad not present. Thermal resistance θJA = 63°C/W (typical, with PCB copper plane).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT1 (Pin 1) | Regulator 1 output | Delivers regulated 5.0 V to first load domain; requires ≥1 µF output capacitor for stability. |
| GND1 (Pin 2) | Regulator 1 ground return | Must connect to system ground; separate from GND2 to avoid crosstalk in split-ground layouts. |
| VOUT2 (Pin 3) | Regulator 2 output | Independent 5.0 V rail-enables dual-voltage domains (e.g., core + I/O) or redundancy. |
| GND2 (Pin 4) | Regulator 2 ground return | Provides isolated return path; tie to same ground as GND1 only if single-supply operation is required. |
| EN2 (Pin 5) | Active-high enable for Regulator 2 | Drives ON when ≥2.0 V applied; floating state is forbidden-must be pulled high or low via resistor. |
| VIN2 (Pin 6) | Input for Regulator 2 | Accepts 2.5–26 V; may be tied to VIN1 or powered separately for isolated input domains. |
| EN1 (Pin 7) | Active-high enable for Regulator 1 | Enables/disables VOUT1 independently-supports sequenced power-up or dynamic rail control. |
| VIN1 (Pin 8) | Input for Regulator 1 | Primary input source; reverse-battery protected-survives –20 V transients without damage. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Two fully isolated 100 mA regulators with separate inputs, enables flexible power sequencing and fault containment. |
| Zero-off mode current | 0.01 µA shutdown current extends battery life in sleep modes-critical for IoT edge nodes and handheld devices. |
| Reverse-battery protection | Withstands –20 V on VIN pins-eliminates need for external series diodes in automotive or field-replaceable battery systems. |
| No-load stability | Remains in regulation with 0 mA load-supports CMOS RAM keep-alive and always-on real-time clock circuits. |
| Low thermal drift | 40 ppm/°C output voltage temperature coefficient-maintains tight regulation across industrial temperature range. |
Applications
| Barcode Scanners | PCMCIA Card Regulation |
|---|---|
Use Scenario: Portable handheld scanners using dual-voltage logic (e.g., 5 V MCU + 3.3 V image sensor interface). IC Role / Device Role / Timing Role: Dual 5.0 V LDO providing independent, sequenced power to processor and peripheral ASICs. Use Value: Enables compact form factor by replacing two discrete regulators; reverse-battery protection prevents damage during hot-swap battery insertion. |
Use Scenario: PCMCIA Type II card requiring separate VCC (5 V) and VPP (12 V) rails-VPP generated via charge pump from VCC. IC Role / Device Role / Timing Role: Primary VCC regulator supplying stable 5.0 V to card controller and memory; second LDO powers auxiliary circuitry. Use Value: Low dropout allows operation down to 5.225 V input-maximizing usable battery voltage range before brownout. |
| Laptop Subsystem Power | SMPS Post-Regulator |
Use Scenario: Always-on subsystems (e.g., keyboard controller, RTC, wake-on-LAN) in notebooks with shared battery rail. IC Role / Device Role / Timing Role: Dual LDO delivering isolated 5.0 V rails-one always enabled, one controlled by host CPU for dynamic power gating. Use Value: 0.01 µA shutdown current minimizes standby drain; independent enables support precise power-state transitions. |
Use Scenario: Clean 5.0 V supply for analog sensors or precision ADCs downstream of noisy buck converter. IC Role / Device Role / Timing Role: Low-noise, high-PSRR post-regulator suppressing switching ripple from upstream SMPS. Use Value: 75 dB PSRR reduces 100 kHz–1 MHz ripple by >300×; 100 µV RMS output noise preserves signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5219-5.0YM | Single-output 100 mA LDO; same SOIC-8 package, identical 5.0 V accuracy and dropout, but no dual-rail capability. | Suitable only where one regulated 5.0 V rail is needed-lacks independent enable and dual-output flexibility. | Select when board space or BOM count must be minimized and dual regulation is unnecessary. |
| TPS7A2050PDBVR | Single 500 mA LDO in SOT-23-5; 170 mV dropout at 500 mA, 25 µA quiescent current, no reverse-battery protection. | Higher current capacity but no dual output or reverse-polarity hardening-requires external diode for battery reversal. | Choose for higher-current single-rail apps where size is critical and reverse-battery risk is mitigated externally. |
Compared with MIC5219-5.0YM and TPS7A2050PDBVR, the MIC5202-5.0YM uniquely delivers dual independent 5.0 V rails with zero-off current and reverse-battery tolerance-making it irreplaceable in compact, battery-critical dual-domain systems where reliability and sequencing matter.

FAQ
What is the maximum continuous output current per channel for MIC5202-5.0YM?
The MIC5202-5.0YM delivers up to 100 mA of continuous output current per regulator channel under specified thermal conditions. This rating assumes adequate PCB copper area and ambient temperature ≤+25°C; derating applies above 25°C per the thermal resistance (θJA = 63°C/W) and maximum junction temperature of +125°C. At 100 mA, dropout is 225 mV and ground current is 1.2 mA typical.
Does MIC5202-5.0YM support independent enable control for each regulator?
Yes, MIC5202-5.0YM provides two independent active-high enable inputs: EN1 (Pin 7) controls Regulator 1 (VOUT1/VIN1), and EN2 (Pin 5) controls Regulator 2 (VOUT2/VIN2). Each pin requires ≥2.0 V to enable and ≤0.7 V to disable. Neither pin may float-external pull-up or pull-down resistors are mandatory to ensure deterministic operation.
What is the dropout voltage specification for MIC5202-5.0YM at full load?
At 100 mA output current, the MIC5202-5.0YM has a dropout voltage of 225 mV (typical) and up to 350 mV (maximum), defined as the VIN–VOUT differential at which output drops 2% below nominal 5.0 V. This enables regulation from as low as 5.225 V input at full load-critical for extending battery runtime in single-cell Li-ion or multi-cell alkaline systems.
Is MIC5202-5.0YM protected against reverse battery connection?
Yes, MIC5202-5.0YM includes integrated reverse-battery protection on both VIN1 and VIN2 pins, allowing it to withstand –20 V input without damage or excessive current draw. This eliminates the need for external series diodes in battery-powered equipment, reducing voltage loss and board area while improving reliability during field maintenance or hot-swap events.
What output capacitor value is required for stable operation of MIC5202-5.0YM?
MIC5202-5.0YM requires a minimum 1 µF output capacitor per channel for stability-tantalum or aluminum electrolytic types are recommended. For loads <10 mA, capacitance may be reduced to 0.47 µF; for <1 mA, 0.33 µF is sufficient. ESR should be ≤5 Ω, and resonance frequency >500 kHz. Larger values improve transient response but increase cost and footprint.
