MIC5252-2.85YM5 TR

Product Overview

The MIC5252-2.85YM5 TR from Microchip Technology is a surface-mount linear voltage regulator that provides a fixed positive 2.85 V output from a single regulator channel. The device accepts an input voltage up to 6 V and delivers up to 150 mA to the load. Its maximum dropout voltage is specified as 0.25 V at 150 mA, and its quiescent current is 150 µA, with maximum supply current of 200 µA. An enable control feature is available, and protection functions include over-current, over-temperature, and under-voltage lockout. The regulator is supplied in a SOT-23-5 package and is rated for a junction temperature range of -40°C to 125°C.

Key Features

• Fixed 2.85 V positive output with a single regulator channel.
• Maximum input voltage of 6 V and output current rating of 150 mA.
• Maximum dropout voltage of 0.25 V at 150 mA.
• Quiescent current of 150 µA and maximum supply current of 200 µA.
• Power-supply rejection ratio of 63 dB to 48 dB from 10 Hz to 10 kHz.
• Enable control feature is available.
• Over-current, over-temperature, and under-voltage lockout protection.
• Surface-mount SOT-23-5 package with operating junction temperature range of -40°C to 125°C.

Applications

• Regulating a fixed 2.85 V rail for low-current analog or mixed-signal circuitry.
• Supplying a fixed 2.85 V output to compact digital or sensor interface boards.
• Using the enable control to gate a 2.85 V rail in subsystems that require output control.
• Providing local regulation from an input up to 6 V in space-constrained surface-mount designs.

Design & Procurement Notes

Design considerations should keep the input voltage at or below 6 V and provide at least 0.25 V of headroom at the 150 mA load point to maintain regulation. The fixed 2.85 V output limits the regulator to applications requiring that single voltage, and the 150 mA output rating should be treated as the maximum load current. The enable control allows the output rail to be enabled or disabled, while over-current, over-temperature, and under-voltage lockout features support protected operation within the specified junction temperature range. The SOT-23-5 surface-mount package and 63 dB to 48 dB PSRR from 10 Hz to 10 kHz are relevant when selecting the device for compact boards or noise-sensitive 2.85 V rails.
