Product details
Overview
MIC5216-3.3YMM-TR from Micrel is a fixed-output 3.3V, 500mA-peak low-dropout linear regulator in an 8-pin MM8™ MSOP package, featuring 1% output voltage accuracy, <500mV dropout at full load, and CMOS/TTL-compatible enable control. It delivers high inrush current for startup in battery-powered portable electronics while maintaining low-noise, low-quiescent-current operation.
For engineers reviewing the MIC5216-3.3YMM-TR datasheet, MIC5216-3.3YMM-TR pinout, MIC5216-3.3YMM-TR application, or MIC5216-3.3YMM-TR equivalent, key selection criteria include peak current capability under thermal constraints, undervoltage flag behavior, dropout performance at 150mA–500mA loads, and compatibility with 2.5V–12V input rails in space-constrained designs.
Technical Context
The MIC5216-3.3YMM-TR integrates a precision bandgap reference, error amplifier, and PMOS pass transistor to achieve tight line (0.05%/V) and load regulation (0.5% over 100µA–150mA). Its internal undervoltage monitor drives an open-collector FLG pin active-low at –5% VOUT deviation with 3% hysteresis.
Thermal protection and current limiting are implemented via on-die sensing; shutdown reduces quiescent current to ≤0.1µA. The device operates across –40°C to +125°C and supports stable regulation down to zero load, enabling CMOS RAM keep-alive applications without external bias.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC5209-3.3YM | Higher continuous current (1.5A), larger SOT-23-5 package, no FLG pin | Lacks undervoltage monitoring; suited for higher steady-state loads without fault reporting | Select when peak current >500mA is needed continuously and flag functionality is unnecessary |
| TPS76333DBVR | 300mA continuous, 400mA peak, 1.2µA quiescent, same 3.3V output and SOT-23-5 footprint | No FLG output; lower peak current but superior shutdown current for long-term storage | Choose for ultra-low-power sleep modes where 500mA peak is not required |
Compared with MIC5216-3.3YMM-TR, MIC5209-3.3YM trades fault reporting for higher sustained current, while TPS76333DBVR sacrifices peak capability and flag functionality to minimize quiescent draw-making MIC5216-3.3YMM-TR uniquely balanced for portable systems needing both startup surge and intelligent supervision.

FAQ
What is the maximum input voltage rating for MIC5216-3.3YMM-TR?
The absolute maximum input voltage for MIC5216-3.3YMM-TR is +20V, but the recommended operating range is 2.5V to 12V. Exceeding 12V increases power dissipation and thermal stress; for 3.3V output, typical designs use ≤6.2V input to maintain safe junction temperature in the MM8 package at 150mA continuous load.
Does MIC5216-3.3YMM-TR require an external pull-up resistor on the FLG pin?
Yes, MIC5216-3.3YMM-TR's FLG pin is open-collector and must be pulled up externally-typically to the IN rail via a 10kΩ–100kΩ resistor-to generate a valid logic-high signal when no undervoltage fault is present. Leaving FLG unconnected disables fault reporting.
Can MIC5216-3.3YMM-TR operate with no load connected to the OUT pin?
Yes, MIC5216-3.3YMM-TR remains stable and in regulation with zero load current, unlike many LDOs that require minimum load for stability. This makes MIC5216-3.3YMM-TR suitable for CMOS RAM keep-alive rails and other ultra-low-power standby applications.
What is the thermal resistance (θJA) of the MIC5216-3.3YMM-TR package?
The MM8™ MSOP-8 package of MIC5216-3.3YMM-TR has a junction-to-ambient thermal resistance of 160°C/W on a minimum recommended footprint and 70°C/W on a 1-inch² copper-clad board. These values assume standard PCB layout per Micrel Application Hint 17 and directly impact maximum sustainable output current.
How does the enable pin (EN) interface with microcontroller GPIOs?
The EN pin of MIC5216-3.3YMM-TR is CMOS/TTL-compatible: logic high ≥2.0V enables regulation, logic low ≤0.4V disables it. It draws ≤5µA at VENH, allowing direct connection to 3.3V or 5V MCU I/O pins without level-shifting or current-limiting resistors.
