Package：ZIP10

STA801M is a 0.5A x 2 output switching regulator in a 10-pin single in line package. The device includes a built-in high side switching element and a flywheel diode, which enables 2 output power supply circuit to be constructed with only a few components. Output voltage of Ch1 is fixed at 5V, however voltage of Ch2 can be selected from 9C, 11.5V, 12.1V, 15.5V by setting the Vo2Cont pin together with the sensing pin. With internally-adjusted phase compensation, the product has been adjusted to work in accoradance with the set Vo. Includes a soft start circuit (output ON/OFF available), and a built in overcurrent and thermal protection circuits.
