Detailed Description for MIC5317-1.8YMT-TZ
Product Overview
The MIC5317-1.8YMT-TZ from Microchip Technology is a single-output linear voltage regulator that provides a fixed positive 1.8 V output at up to 150 mA. The device uses a surface-mount 4-DFN (1x1) package with an exposed pad and operates over a -40°C to 125°C temperature range. Its input voltage maximum is 6 V, and the dropout voltage is specified as 0.38 V at 150 mA. The regulator includes an enable control feature and protection against over-current and over-temperature conditions.
Key Features
- Fixed positive 1.8 V output with 150 mA output current capability.
- Maximum input voltage of 6 V and dropout voltage of 0.38 V at 150 mA.
- Quiescent current of 39 µA and PSRR of 80 dB to 65 dB from 1 kHz to 10 kHz.
- Enable control feature for on/off regulation control.
- Integrated over-current and over-temperature protection features.
- Surface-mount 4-UDFN exposed pad package, supplier device package 4-DFN (1x1).
- Operating temperature range of -40°C to 125°C.
Applications
- Fixed 1.8 V rail for digital logic subsystems requiring up to 150 mA.
- Enable-controlled 1.8 V output for power sequencing in embedded controller boards.
- Regulated 1.8 V supply for compact sensing or communication modules within the 150 mA limit.
Design & Procurement Notes
Design considerations include selecting input filtering and layout for the 6 V maximum input and 150 mA output, and using the 0.38 V dropout value to maintain headroom at load current. The enable control can be used to sequence or disable the 1.8 V output, while the over-current and over-temperature protections support operation within the -40°C to 125°C range. The 4-DFN (1x1) surface-mount package with exposed pad requires attention to thermal connection and solder land pattern.
