DESCRIPTION
The SAT05D is a non-isolated Dual Output Switching regulator for high reliability and full military
distributed power, point of load applications. Fully integrated, the SAT05D-Adj includes boost
controller, inductor, and input/output capacitors integrated in a single package. The SAT05D-Adj
operates from a single +5V supply and provides up to 30mA of output current on the positive output and
up to 15mA of current at the negative output. Careful design and layout ensure excellent stability,
transient response, and low noise operation. Packaged in a compact, surface mount package, the
SAT05D-Adj is manufactured to operate over the full,

The negative output can be trimmed by using a shunt resistor between the outputs of Neg. trim 1, Neg. trim 2 and +Out. The
negative output (absolute value), will typically be slightly greater than the positive output Adding trim resistors will allow a
negative output attenuation. Recommended values for Rtrim: 0- 100 ohms. If not needed, these pins may be left open.
