Frequently Asked Questions

What is the reset threshold voltage of the TPS3809L30DBVR?

The TPS3809L30DBVR has a fixed reset threshold of 3.0V with ±2% accuracy. When the supply voltage drops below this threshold, the active-low reset output is asserted to hold the processor in reset, preventing erratic operation during brownout conditions.

What package does the TPS3809L30DBVR use and what are its dimensions?

The TPS3809L30DBVR is available in a 3-pin SOT-23 (DBV) package. This ultra-compact surface-mount package measures approximately 2.9mm x 1.6mm, making it ideal for space-constrained designs in portable and wearable electronics.

Can the TPS3809L30DBVR be used with 3.3V microcontroller systems?

Yes, the TPS3809L30DBVR is well-suited for 3.3V systems. Its 3.0V threshold ensures the microcontroller is held in reset when the supply is below safe operating levels, and the push-pull output is directly compatible with 3.3V logic without requiring external pull-up resistors.

What is the power-on reset timeout delay of the TPS3809L30DBVR?

The TPS3809L30DBVR provides a 200ms power-on reset timeout delay after the supply voltage rises above the 3.0V threshold. This delay ensures the supply is fully stable before releasing the reset signal, allowing the microcontroller or processor to start up correctly.
