FEATURES
DESCRIPTION
The TLV803 family of supervisory circuits provides

3-Pin SOT23 Package
circuit initialization and timing supervision, primarily
Supply Current: 9
µA (Typical)
for DSPs and processor-based systems.
Precision Supply Voltage Monitor:
During power-on, RESET asserts when the supply

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

Portable/Battery-Powered Equipment
Programmable Controls
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 package. The TLV803
