General Description
The TS2576 Series are step-down switching regulators with all required active functions. It is capable of driving 3A load
with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an
adjustable output version.
The TS2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. Also it requires a
minimum number of external components. It substantially not only reduces the area of board size but also the size of heat
sink, and in some cases no heat sink is required. The ±4% tolerance on output voltage within specified input voltages and
output load conditions is guaranteed. Also, the oscillator frequency accuracy is within ±10%. External shutdown is
included. Featuring 70μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as
thermal shutdown for full protection under fault conditions.
This series are offered in 5-pin TO-263, TO-220 package.
