MIC5256-2.6YM5-TR

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

The MIC5256-2.6YM5-TR is a fixed-output linear regulator providing 2.6V at up to 150mA. It operates within a 2.7V to 6.0V input range and features an error flag for fault indication. Key electrical parameters include 90µA quiescent current, 135mV typical dropout voltage at 150mA, and 1% initial output accuracy. The device includes thermal shutdown and current limit protection.

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

• Integrated open-drain error flag indicates undervoltage conditions caused by overcurrent, thermal shutdown, or dropout.
• TTL-compatible enable pin allows active shutdown with near-zero off-mode current consumption.
• Stable with low-ESR ceramic capacitors, optimizing board space for handheld applications.
• Active shutdown clamp discharges the output capacitor when disabled.

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

Verify the package type matches the ordering suffix: M5 denotes SOT-23-5, while D5 denotes TSOT-23-5. Confirm the temperature range code Y corresponds to -40°C to +125°C. Ensure the media type TR indicates tape and reel packaging of 3,000 units per reel. Cross-reference the specific output voltage code 2.6 with the datasheet product identification system.

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

Select this component for designs requiring precise voltage regulation in battery-operated systems. The low dropout characteristic supports operation from single-cell lithium batteries. The inclusion of an error flag facilitates system monitoring without additional logic. Verify that the required output current does not exceed the 150mA continuous rating under maximum ambient temperatures.

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

How does the error flag function?

The error flag is an active-low, open-drain output that drives low when a fault condition (overcurrent, thermal shutdown, or dropout) occurs simultaneously with an output undervoltage detection.

What are the requirements for the enable pin?

The enable pin is TTL-compatible and cannot be left floating. A logic-high enables the regulator, while a logic-low activates the zero off-mode current state.
