MIC5308-1.5YD6-TR

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

The MIC5308-1.5YD6-TR is a fixed-output low dropout regulator providing a 1.5V output with up to 150mA current capability. It operates from an input voltage range of 1.6V to 5.5V and utilizes a separate bias supply ranging from 2.5V to 5.5V. The device features ultra-low ground current, typically 23µA under full load, and achieves a maximum dropout voltage of 150mV at 150mA. Power Supply Rejection Ratio reaches up to 90dB at 1kHz. It is housed in a 6-pin TSOT-23 package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

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

Verify the specific ordering suffix 'YD6' confirms the 6-pin TSOT-23 package configuration rather than the Thin MLF variant. Ensure the design accommodates the required external components, specifically a minimum 1µF ceramic output capacitor and a 1µF input capacitor, to maintain stability. Confirm that the bias supply voltage requirements align with system power rails before finalizing procurement.

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

Select this component for applications requiring regulation from very low input voltages down to 1.5V. The dual-supply design is optimal for systems where a dedicated bias rail exists or can be generated. Consider the TSOT-23 package for cost-sensitive designs compared to the MLF option. Verify that the 150mA continuous current rating meets peak load demands without exceeding thermal limits in the target enclosure.

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

This part belongs to the MIC5308 family of µCap low dropout regulators manufactured by Micrel (now Microchip Technology). The series is characterized by high performance and fast transient response suitable for digital loads. The MIC5308-1.5YD6-TR represents the fixed 1.5V output version packaged in TSOT-23, distinguishing it from adjustable variants and other package options within the same functional family.

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

MIC5308-1.5YMT-TR provides identical electrical specifications but uses a 6-pin Thin MLF package instead of TSOT-23.
