TLV70028DCKR 詳細描述
Product Overview
TLV70028DCKR from Texas Instruments is a single-output linear voltage regulator that provides a fixed 2.8 V positive rail from inputs up to 5.5 V. The device is rated for 200 mA output current and specifies a maximum dropout voltage of 0.25 V at 200 mA. It includes an enable control feature and protection against over-current, over-temperature, reverse-polarity, and under-voltage lockout conditions. The regulator is supplied in a 5-TSSOP, SC-70-5, SOT-353 surface-mount package and is specified for operation from -40°C to 125°C junction temperature.
Key Features
- Fixed 2.8 V positive output with 200 mA rated output current
- Maximum input voltage of 5.5 V and maximum dropout voltage of 0.25 V at 200 mA
- 55 µA quiescent current and 270 µA maximum supply current
- 68 dB power-supply rejection ratio at 1 kHz
- Enable control feature for regulator state management
- Over-current, over-temperature, reverse-polarity, and under-voltage lockout protection features
- Surface-mount 5-TSSOP, SC-70-5, SOT-353 package
- Junction temperature range of -40°C to 125°C
Applications
- Low-power logic circuits requiring a fixed 2.8 V rail from a 5.5 V supply
- Compact board designs using an enable-controlled local power domain
- Sensor or interface boards needing linear regulation with over-current and over-temperature protection
- Supply inputs requiring reverse-polarity and under-voltage lockout protection
Design & Procurement Notes
Designers should verify that the available input voltage remains above the 2.8 V output plus the 0.25 V dropout margin at the intended load current, and does not exceed the 5.5 V maximum input rating. The enable control can be used to turn the regulator on or off in a board-level power sequence. The 55 µA quiescent current and 270 µA maximum supply current should be considered in low-power budget calculations. Because the device is specified for a junction temperature range of -40°C to 125°C, thermal design should account for the SC-70-5 surface-mount package and the expected operating conditions. The over-current, over-temperature, reverse-polarity, and under-voltage lockout protection features should be considered within the overall system fault-handling design.
