MIC5320-SFYMT-TR

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

The MIC5320-SFYMT-TR is a dual ultra-low-dropout linear regulator manufactured by Microchip Technology. It provides two independent fixed outputs of 3.3V and 1.5V, each capable of delivering up to 150mA. The device operates with an input voltage range of 2.3V to 5.5V. It features a low quiescent current of 85µA per output and achieves an ultra-low dropout voltage of 35mV at 150mA. The component is housed in a compact 6-pin 1.6mm x 1.6mm Thin MLF package.

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

Verify the specific suffix YMT corresponds to the 6-pin 1.6mm x 1.6mm Thin MLF leadless package configuration. Confirm that the manufacturing part number marking ASF aligns with the required identification standards. Ensure compliance with the specified junction temperature range of -40°C to +125°C for the target application environment.

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

Select this component when dual isolated power rails are required within a constrained footprint. The 3.3V/1.5V combination suits systems needing standard logic levels alongside lower voltage cores. Verify that the total load does not exceed the thermal dissipation limits defined by the junction-to-ambient resistance of the selected package.

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

What is the minimum capacitance required for stability?

The MIC5320 requires a minimum of 1µF ceramic capacitor on both the input and output sides to maintain stability.

How are the regulators disabled?

Each regulator has an independent active-high enable pin. Driving the pin low disables the respective output, resulting in near-zero off-mode current.
