Detailed Description for STLQ015M28R
Product Overview
STMicroelectronics STLQ015M28R is a positive fixed-output linear voltage regulator in a surface-mount SOT-23-5 package. It provides a single 2.8V output at up to 150mA, with a maximum input rating of 5.5V. The device includes an enable control feature and protection against over-current and over-temperature conditions. Its low quiescent current and compact package make it suitable for space-constrained power rails where a fixed 2.8V supply is required.
Key Features
- Fixed 2.8V positive output from a single linear regulator channel.
- Rated output current of 150mA with maximum dropout of 0.3V at 150mA.
- Maximum input voltage of 5.5V and quiescent current of 1.7 µA.
- Maximum supply current of 2.4 µA.
- Enable control feature for controlled output operation.
- Over-current and over-temperature protection features.
- Surface-mount package: SC-74A, SOT-753, SOT-23-5.
- Operating junction temperature range of -40°C to 125°C.
- Power supply rejection ratio of 40dB to 15dB from 1kHz to 100kHz.
Applications
- 150mA 2.8V supply rail for compact battery-powered devices.
- Sensor or interface circuitry requiring a fixed positive voltage with enable control.
- Enable-controlled power distribution in small surface-mount assemblies.
Design & Procurement Notes
Designers should verify that the input voltage remains within the 5.5V maximum rating and that the input-to-output differential accounts for the 0.3V dropout condition at 150mA. The fixed 2.8V output means this regulator is selected for rails requiring that exact voltage rather than adjustable output. The enable control feature supports controlled output operation, while over-current and over-temperature protection support fault conditions. Thermal design should keep the junction temperature within the -40°C to 125°C operating range, and the SOT-23-5 surface-mount package requires an appropriate PCB footprint.
