Detailed Description for MIC5302-1.8YMT-TR
Product Overview
The MIC5302-1.8YMT-TR from Microchip Technology is a positive fixed-output linear voltage regulator for a single 1.8V rail at up to 150mA. It accepts an input voltage up to 5.5V and provides a maximum dropout of 0.1V at 150mA, supporting compact power delivery in surface-mount designs. The 4-TMLF package measures 1.2x1.6 and includes an exposed pad, while enable control and over-current and over-temperature protection are integrated.
Key Features
- Fixed positive 1.8V output from one regulator
- 150mA output current capability
- Maximum dropout of 0.1V at 150mA
- Input voltage rating up to 5.5V
- Quiescent current of 120 µA
- Power supply rejection ratio of 65dB at 1kHz and 42dB at 20kHz
- Enable control feature
- Over-current and over-temperature protection
- Operating temperature range from -40°C to 125°C
- Surface-mount 4-TMLF package with exposed pad, 1.2x1.6
Applications
- Low-current 1.8V logic rail generation in portable electronics
- Post-regulation from a higher supply voltage to power microcontroller or sensor interfaces
- Local voltage regulation on densely populated surface-mount boards where a compact package is useful
Design & Procurement Notes
For circuit planning, the fixed 1.8V output requires an input voltage no higher than 5.5V and sufficient headroom above 1.8V plus the 0.1V dropout at 150mA. The enable control can be used to manage the regulator output without changing the fixed voltage setting. The 1.2x1.6 4-TMLF package and exposed pad require a matching surface-mount land pattern and attention to board thermal handling. When input noise rejection matters, evaluate the specified PSRR values at 1kHz and 20kHz.
