MIC5363-1.2YMT-T5

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

The MIC5363-1.2YMT-T5 is a single-output, fixed-voltage Low Dropout (LDO) regulator manufactured by Microchip Technology. It provides a nominal output voltage of 1.2V with a maximum continuous output current of 300mA. The device operates within an input voltage range of 2.5V to 5.5V and features high power supply rejection ratio (PSRR) performance of 70dB at 1kHz. Output accuracy is maintained within ±2% tolerance across the operating temperature range of -40°C to +125°C. The regulator utilizes a 6-pin 1.2mm x 1.2mm Thin MLF® package and requires 1µF ceramic capacitors for stability.

Validate PCB footprint alignment with 6-pin 1.2mm x 1.2mm Thin MLF® specifications. Check RoHS compliance status prior to integration.

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

Select this component when designing portable systems requiring stable 1.2V rails under 300mA loads. Consider the 225mV dropout voltage at full load for battery efficiency. Evaluate thermal dissipation capabilities based on ambient temperature and PCB layout constraints. Verify compatibility with 1µF X5R or X7R ceramic capacitors for optimal stability and transient response.

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

This part belongs to the MIC5363/4 series of µCap LDO regulators designed for general-purpose portable devices. The MIC5363 variant lacks the auto-discharge feature found in the MIC5364 counterpart. Both share identical electrical characteristics except for the output discharge function upon shutdown. The series targets applications demanding high PSRR and small form factors.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

MIC5363-1.2YMT serves as the base part number. The MIC5364-1.2YMT offers identical electrical performance but includes an active output discharge circuit. Substitution requires verifying if the auto-discharge feature is necessary for the specific application timing requirements.
