MIC5392-SSYMT-TR

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

The MIC5392-SSYMT-TR is a dual low-dropout linear regulator from Microchip Technology, integrating two independent 150mA LDOs into a compact 6-pin 1.2mm × 1.2mm Thin DFN package. It operates with an input voltage range of 2.5V to 5.5V and provides fixed 3.3V outputs on both channels. The device features high output accuracy (±2% initial), low quiescent current (32µA per LDO), and superior ripple rejection (>60dB at 1kHz). Designed for stability with small ceramic capacitors, it includes independent enable pins, thermal shutdown, and current-limit protection.

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

Verify the specific suffix 'SSYMT' confirms the 3.3V/3.3V fixed output configuration and the standard 1.2mm x 1.2mm Thin DFN package type. Confirm that the component is sourced directly from authorized Microchip distributors or Micrel representatives to ensure authenticity. Check for any recent Product Change Notices regarding packaging or manufacturing site updates before finalizing procurement orders.

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

Select this component when space-constrained designs require dual regulated rails with minimal external components. It is suitable for applications needing high ripple rejection and independent channel control. Ensure the design accommodates the required 1µF ceramic output capacitors for stability. Consider the thermal resistance characteristics if operating near maximum ambient temperatures or continuous load limits.
