MIC5213-3.3BC5-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5213-3.3BC5-TR is a fixed-output linear voltage regulator providing 3.3V at up to 80mA in an SC-70-5 package. It operates with an input voltage range of 2.5V to 16V and maintains junction temperatures from -40°C to +125°C. The device features low dropout voltage, typically 20mV at light loads and 300mV at full load, alongside a quiescent ground current of 225µA at 20mA output. Initial accuracy is better than 3%, and it requires only 0.47µF of output capacitance for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix 'BC5' against official Microchip documentation to confirm the exact temperature grade and lead-free status associated with this variant. Ensure compatibility with standard surface-mount assembly processes for the SC-70-5 footprint. Cross-reference datasheet electrical characteristics with actual system requirements before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring a compact form factor with half the footprint of standard SOT-23 packages. It is suitable for battery-powered designs due to low ground current that increases only slightly during dropout conditions. Consider thermal resistance limits when calculating maximum allowable power dissipation for high-load scenarios in small enclosures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MIC5213 Teeny™ series of low-dropout regulators manufactured by Micrel (now Microchip Technology). The series offers various fixed output voltages including 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, and 5.0V. All variants share the same SC-70-5 package and core regulatory features designed for handheld and portable electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include MIC5213-3.0BC5-TR, MIC5213-3.6BC5-TR, and MIC5213-5.0BC5-TR, which share identical packaging and pinouts but provide different fixed output voltages. Verify that the target application circuit can accommodate the specific voltage difference if swapping between these variants.
