MIC5335-KDYMT

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

The MIC5335-KDYMT is a dual-output Ultra Low Dropout (ULDO) linear regulator manufactured by Micrel. It integrates two independent 300mA LDOs within an ultra-thin 1.6mm x 1.6mm 6-lead Thin MLF package. The device operates with an input voltage range of 2.3V to 5.5V and features µCap stability, allowing the use of small ceramic output capacitors. Key electrical parameters include a dropout voltage of 75mV at 300mA, high PSRR exceeding 65dB, and low quiescent current of 90µA per LDO.

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

Verify the specific output voltage configuration associated with the KDYMT suffix against official Microchip documentation, as suffixes typically denote fixed voltage combinations. Confirm the package type matches the required 1.6mm x 1.6mm footprint. Ensure compatibility with surface mount assembly processes suitable for thin MLF packages. Check for RoHS compliance status in the latest datasheet.

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

Select this component when space constraints are critical due to its compact 1.6mm x 1.6mm package size. Choose this regulator for applications requiring dual independent outputs from a single IC to reduce board area. Consider this part for designs needing high PSRR without additional filtering components. Evaluate thermal performance requirements given the small footprint and potential power dissipation.
