MIC5317-2.8YMT-TZ 詳細描述
Product Overview
Microchip Technology MIC5317-2.8YMT-TZ is a positive fixed-output linear voltage regulator intended for single 2.8 V rails. The device provides up to 150 mA output current, accepts input voltages up to 6 V, and specifies a maximum dropout of 0.31 V at 150 mA. It includes enable control, overcurrent and overtemperature protection, and is supplied in a surface-mount 4-DFN 1x1 package with an exposed pad.
Key Features
- Fixed positive 2.8 V output with one regulator and a 150 mA output current rating.
- Maximum input voltage of 6 V and maximum dropout of 0.31 V at 150 mA.
- 39 µA quiescent current for low-power supply-rail management.
- Enable control for switching the regulator output on or off.
- Overcurrent and overtemperature protection features.
- Power supply rejection ratio of 80 dB to 65 dB from 1 kHz to 10 kHz.
- Operating temperature range of -40°C to 125°C.
- Surface-mount 4-UDFN exposed-pad package, 4-DFN 1x1.
Applications
- A fixed 2.8 V rail for low-current portable equipment where enable control and 39 µA quiescent current are useful.
- Linear regulation for analog sensor or mixed-signal circuits that need a positive fixed voltage and input ripple rejection from 1 kHz to 10 kHz.
- A 2.8 V supply for compact surface-mount boards powered from input voltages up to 6 V and drawing no more than 150 mA.
Design & Procurement Notes
Designers should confirm that the system rail is fixed at 2.8 V, since the output is not adjustable, and that the input voltage remains within the 6 V maximum. The 0.31 V maximum dropout at 150 mA sets the minimum practical headroom under full load, while the 150 mA output current limit defines the maximum continuous load. The enable control allows the output to be switched on or off; the desired state should be defined during system startup and shutdown. The overcurrent and overtemperature protections should be treated as safeguards rather than substitutes for correct sizing. The 4-DFN 1x1 surface-mount package with exposed pad requires an appropriate PCB footprint and pad handling. The -40°C to 125°C operating range and 80 dB to 65 dB PSRR from 1 kHz to 10 kHz support use in low-current linear regulation where supply noise rejection and temperature range are relevant.
