GND
During power-on, RESET is asserted when the
supply voltage VDD becomes higher than 1.1 V.
Thereafter, the supervisory circuit monitors VDD and
keeps RESET active as long as VDD remains below
the threshold voltage VIT. An internal timer delays the
return of the output to the inactive state (high) to
ensure proper system reset. The delay time, td(typ) =
200 ms, starts after VDD has risen above the
threshold voltage VIT. When the supply voltage drops
below the threshold voltage VIT, the output becomes
active (low) again. No external components are
required. All the devices of this family have a fixed
sense-threshold voltage VIT set by an internal voltage
divider.
The product spectrum is designed for supply voltages
of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are
available in a 3-pin SOT-23. The TPS3809 devices
are characterized for operation over a temperature
range of –40°C to 85°C.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to GND. For reliable operation, the device should not be operated at 7 V for more than t = 1000h

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
