DESCRIPTION
The ST730A is a 5V output CMOS, step-down
switching regulator. The ST730A accepts inputs
between 5.2V and 11V and delivers 450mA.
Typical efficiencies are 85% to 96%.
Quiescent supply current is 0.8mA and only 0.3

frequency over this specified range. Pulse-width
modulation (PWM) current-mode control provides
precise output regulation and excellent transient
responses.
