TPS70630DBVR

TPS70630DBVR is TI’s fixed-output, low-dropout regulator (LDO) in the TPS70630 family. It provides a stable 3.0-V rail from a single supply with ultra-low quiescent current and fast transient response, ideal for battery-powered devices. The DBVR suffix indicates the tiny SOT-23-5 package variant with an enable/shutdown input and built-in protection (overcurrent/short-circuit and thermal shutdown). As a fixed-output part, no external feedback resistors are needed.
Common applications: power for microcontrollers, sensors, RF front-ends, and other low-power circuits in wearables, IoT, and portable electronics.
How to use: connect Vin to the input (with the recommended input capacitor), connect GND to ground, and connect Vout to your load (with the recommended output capacitor). Drive EN high to enable; pull EN low to disable. Follow TI’s layout and stability guidelines for best results.

TPS70630DBVR is a fixed 3.0-V LDO regulator (≈150 mA) with enable. TI equivalents: TLV70030 (3.0-V fixed, 150 mA) and TPS79330 (3.0-V fixed, 150 mA with enable). For other vendors, use cross-reference tools to find 3.0-V fixed LDOs with similar current and compatible package/pinout.

Here are the key features of the TPS70630DBVR:
- Fixed 3.0 V output
- Up to ~150 mA load current
- Ultra-low quiescent current
- Low dropout voltage
- Enable pin to turn regulator on/off
- Overcurrent protection and thermal shutdown
- Stable with small ceramic output capacitors (1 µF–10 µF, low ESR)
- Wide input range (up to about 5.5 V)
- Good line/load regulation and fast transient response
- Temperature range suitable for typical automotive/industrial use
- Package: DBVR (SOT-23-5), RoHS-compliant
Note: exact numbers (currents, voltage ranges) can vary slightly by revision; consult the datasheet for precise specifications.

- Pin count: 5 pins (SOT-23-5, DBVR package)
- Function: Fixed-output low-dropout voltage regulator (TPS70630) with an enable input. Outputs a fixed 3.0 V from an input typically in the 1.8–5.5 V range.

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits, headquartered in Dallas, Texas.

TPS70630DBVR is a fixed 3.0 V low-dropout regulator. Common application areas include:
