MIC5330-NDYML-TR

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

The MIC5330-NDYML-TR is a dual ultra-low dropout linear regulator from Microchip Technology, integrating two independent 300mA LDOs into an 8-pin 2mm x 2mm MLF package. It operates with an input voltage range of 2.3V to 5.5V and provides fixed output voltages of 2.85V on LDO1 and 1.85V on LDO2. The device features ±2% initial output accuracy, ultra-low output noise of 30µVRMS, and high power supply rejection exceeding 70dB at 1kHz. It includes thermal shutdown, current limit protection, and fast start-up time of 30µs.

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

Compatible substitutes include other MIC5330 variants with different fixed output voltages, such as MIC5330-MFYML (2.8V/1.5V) or MIC5330-KDYML (2.6V/1.85V), provided the voltage requirements match the application design.

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

How does the bypass capacitor affect performance?

Connecting a 0.1µF capacitor from the BYP pin to ground reduces output voltage noise and improves power supply rejection ratio without significantly slowing the turn-on time due to the internal quick start circuit.

What is the recommended output capacitor type?

X7R or X5R dielectric ceramic capacitors are recommended for the 1µF minimum output capacitance due to their temperature stability compared to Z5U or Y5V types.
