The ST763A is a step-down switching regulator. It operates from 3.3V to 11V giving a fixed 3.3V output voltage, delivering up to 500mA. The mainly features are typical efficiency of 90%, quiescent current of 0.6mA, and only 0.2µA in shut-down.
The PWM current mode control provides precise output regulation and very good transient response. Output voltage accuracy is guaranteed to be ±5% over line, load and temperature variations. A minimum number of external components is used and the fixed frequency switching allows easy filtering of output ripple and noise.
Other features of this device are cycle-by-cycle current limiting, overcurrent limiting, under voltage lockout and programmable soft-start protection.
A 22µH inductor works in most applications, so no sophisticated design is necessary.
Package available is SO-8.
Typical application are in 5V to 3.3V converters, cellular phones, portable instruments, hand-held computers, and peripherals.
