ST1S03, step-down switching regulator

ST1S03 1.5 A, 1.5 MHz adjustable, step-down switching regulator DFN6D (3 x 3 mm)

Features

* Step-down current mode PWM (1.5 MHz) DC-DC converter
* 2% DC output voltage tolerance
* Internal soft-start for STARTUP current limitation and power on delay of 50 - 100 µs
* Typical efficiency: > 70% over all operating conditions
* 1.5 A output current capability
* Not swi

Applications

* and, generally, to replace the high current linear solution when the power dissipation may cause a high heating of the application environment. It provides up to 1.5 A over an input voltage range of 3 V to 16 V. A high switching frequency (1.5 MHz) allows the use of tiny surface-mount components: as
