Product details
Overview
MIC5213-2.7YC5-TR from Micrel is a fixed-output 2.7V, 80mA low-dropout linear voltage regulator in the Teeny™ SC-70-5 package. It delivers 2.7V output with ±3% initial accuracy, 300mV dropout at full load, and 225µA ground current at 20mA-optimized for battery-powered handheld devices requiring ultra-small footprint and logic-controlled shutdown.
For engineers reviewing the MIC5213-2.7YC5-TR datasheet, MIC5213-2.7YC5-TR pinout, MIC5213-2.7YC5-TR application, or MIC5213-2.7YC5-TR equivalent, key selection criteria include dropout performance at light-to-full load, enable-input compatibility with TTL/CMOS logic, stability with 0.47µF ceramic output capacitance, and thermal behavior in SC-70-5 layout-constrained designs.
Technical Context
The MIC5213-2.7YC5-TR uses a PNP-based pass transistor architecture enabling low dropout (20mV at 100µA, 300mV at 80mA) and minimal ground current increase in dropout. Its internal enable circuit accepts 0–20V logic-compatible input (VIH ≥ 2.0V, VIL ≤ 0.6V), drawing only 10nA when disabled.
Stability is guaranteed with 0.47µF low-ESR ceramic output capacitors across –40°C to +125°C. Protection features include current limiting (180–250mA), overtemperature shutdown, and reversed-input-polarity protection-critical for single-cell Li-ion and alkaline battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V ±3% at 25°C; supports stable power rail for 2.7V logic or analog subsystems |
| Max Output Current | 80mA continuous; sufficient for low-power microcontrollers, sensors, and RF front-ends |
| Dropout Voltage | 300mV at 80mA; enables operation down to VIN = 3.0V with 2.7V output-ideal for single-cell battery systems |
| Ground Current | 225µA at 20mA; ensures >1000-hour battery life in standby mode for portable devices |
| Enable Threshold | VIL ≤ 0.6V (shutdown), VIH ≥ 2.0V (active); compatible with 1.8V/3.3V/5V logic without level shifters |

FAQ
What is the minimum input voltage required for MIC5213-2.7YC5-TR to maintain regulation?
The MIC5213-2.7YC5-TR maintains regulation as long as input voltage exceeds output voltage plus dropout. At 80mA load, dropout is 300mV, so minimum VIN is 3.0V. At lighter loads (e.g., 100µA), dropout drops to 20mV, allowing VIN as low as 2.72V while sustaining 2.7V output-critical for deep battery discharge scenarios.
Does MIC5213-2.7YC5-TR require an input capacitor?
Yes-MIC5213-2.7YC5-TR recommends a 0.1µF ceramic capacitor from IN to GND when input wiring exceeds 10 inches or when powered directly from a battery. This minimizes input impedance and prevents instability due to source inductance, especially during load transients.
Can MIC5213-2.7YC5-TR operate without a load?
Yes-MIC5213-2.7YC5-TR remains stable and in regulation with no load, unlike many LDOs that oscillate or drop out under no-load conditions. This makes it suitable for CMOS RAM keep-alive circuits and other zero-current standby applications.
What is the thermal resistance (θJA) of MIC5213-2.7YC5-TR in its SC-70-5 package?
The junction-to-ambient thermal resistance (θJA) of MIC5213-2.7YC5-TR in the SC-70-5 package is 450°C/W when mounted on a standard PCB. This value determines maximum power dissipation before thermal shutdown-e.g., at 25°C ambient, PD(max) = (125°C − 25°C)/450°C/W = 222mW.
Is MIC5213-2.7YC5-TR protected against reversed battery connection?
Yes-MIC5213-2.7YC5-TR includes internal reversed-input-polarity protection and can withstand –20V applied to the IN pin without damage. This eliminates the need for an external series diode in battery-powered equipment where accidental reverse insertion is possible.
