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

Verify the specific output voltage configuration matches the application requirements before procurement. Confirm that the supply voltage remains within the specified 2.3 V to 5.5 V operating range. Ensure proper PCB layout guidelines are followed to maintain thermal performance and stability with the required 1 µF ceramic capacitors on both inputs and outputs.

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

Select this component when space-constrained portable designs require dual regulated rails from a single source. The dual enable pins allow for independent power management of different subsystems. Consider the thermal resistance of the TDFN-6 package when calculating maximum ambient temperature limits under full load conditions to ensure reliable operation.

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

What is the minimum output capacitance required for stability?

The MIC5335 requires an output capacitor of 1 µF or greater to maintain stability. Low-ESR ceramic chip capacitors are recommended.

How does the enable pin function operate?

The MIC5335 features dual active-high enable pins. Forcing an enable pin low disables the respective regulator into a zero off-mode current state, while forcing it high enables the output voltage.
