MIC5335-PMYMT-TR

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

The MIC5335-PMYMT-TR is a dual-channel, high-performance 300 mA µCap Ultra-Low Dropout (ULDO) linear regulator manufactured by Microchip Technology. It features two independent LDOs with fixed output voltages of 3.0V and 2.8V. The device operates within an input voltage range of 2.3V to 5.5V and supports a junction temperature range from -40°C to +125°C. Each regulator delivers up to 300mA output current with ultra-low dropout characteristics, achieving 75mV at full load. The unit utilizes a 6-Lead Thin DFN package measuring 1.6 mm x 1.6 mm.

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

Verify the specific suffix 'PM' corresponds to the required 3.0V/2.8V output configuration before procurement. Confirm that the 'Y' suffix indicates the specified -40°C to +125°C operating temperature range. Ensure the 'MT' designation matches the required 6-Lead TDFN package dimensions for your PCB layout. Validate that the 'TR' suffix aligns with your manufacturing requirements for reel packaging quantities.

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 input source. The µCap stability feature simplifies design by allowing the use of minimal 1 µF ceramic capacitors instead of larger tantalum or electrolytic types. Independent enable pins provide efficient power management capabilities for battery-operated systems requiring selective rail activation.

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

This part belongs to the MIC5335 family of dual-channel ULDO regulators designed for high current density in miniature form factors. The series offers various fixed output voltage combinations to suit different logic levels. The PM variant specifically provides 3.0V and 2.8V outputs, catering to applications needing slightly lower voltage rails than standard 3.3V systems.

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

What is the minimum output capacitance required for stability?

The MIC5335 is µCap stable and requires a minimum output capacitance of 1 µF ceramic capacitor for proper operation.

How are the two LDO channels controlled?

Each LDO has its own active-high enable pin (EN1 and EN2), allowing independent on/off control without affecting the other channel.
