DESCRIPTION
The ST735S/ST735T is a Bi-CMOS, inverting
switch mode DC-DC regulator with internal Power
MOSFET that generates a fixed -5V (S version) or
a negative adjustable (T version) output voltage
from a 4V (3.5V for the 735T) to 6.2V input voltage
(9V for the 735T); is guaranteed an output current
of 200mA for inputs greater than 4.5V. The
quiescent current for this device is typically of
0.8mA and, in shutdown mode it is reduced to
1μA.
These power-conserving features, along with high
efficiency and applications circuits, thaT lend itself
to minaturization, make the ST735S/ST735T
excellent in a broad range of on-card, HDD and
portable equipment
applications. These device
employ a high performance current mode pulse
with modulation (PWM) control scheme to provide
tight output voltage regulation and low noise. The
fixed frequency oscillator is factory trimmed to
300KHz, allowing for easy noise filtering. The
regulator in production is tested to guarantee an
output accuracy within ±5% over all specified
conditions.
