MIC5364-2.8YMT-T5

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

The MIC5364-2.8YMT-T5 is a high-performance, fixed-output 2.8V Low Dropout (LDO) voltage regulator manufactured by Microchip Technology. It provides a continuous output current of 300mA with an input voltage range of 2.5V to 5.5V. The device features high power supply rejection ratio (PSRR) of 70dB at 1kHz and low quiescent current of typically 38µA. It incorporates active output discharge circuitry that switches a 30Ω NFET from VOUT to GND when disabled. The component operates within a junction temperature range of -40°C to +125°C and utilizes a 6-pin 1.2mm x 1.2mm Thin MLF® package.

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

Verify the specific ordering suffix 'T5' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and lead finish details directly from the datasheet. Ensure the component matches the original Micrel manufacturing origin prior to acquisition by Microchip Technology.

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

Select this component when a compact footprint is required alongside high PSRR capabilities. The MIC5364 variant is specifically indicated over the MIC5363 when automatic output capacitor discharge functionality is necessary during system shutdown states. Verify thermal dissipation limits based on the 173°C/W junction-to-ambient resistance characteristic of the Thin MLF® package.

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

This part belongs to the MIC5363/4 family of µCap LDO regulators designed for portable devices. The series integrates a 300mA LDO into a 1.2mm x 1.2mm Thin MLF® package. The MIC5364 distinguishes itself from the MIC5363 through the inclusion of an auto-discharge function, while both share identical electrical performance regarding dropout voltage and line regulation.

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

How does the MIC5364 handle output capacitors when disabled?

When the enable pin is driven low, the MIC5364 activates an internal 30Ω NFET connected between VOUT and GND to automatically discharge the external output capacitors.

What type of capacitors are recommended for stability?

The device is optimized for use with low-ESR ceramic chip capacitors. X7R or X5R dielectrics are recommended for both input and output capacitors to ensure stable operation across temperature ranges.
