RT9163
500mA Low Dropout Positive Voltage Regulator
General Description
The RT9163 is a positive low dropout regulator designed
for applications requiring low dropout performance at full
rated current. The device is available in fixed output
voltage of 3.3V, 3.5V, and 5.0V. The RT9163 provides
excellent regulation over line, load, and temperature
variations.
The other features include low dropout performance at a
maximum of 1.4V at 500mA, fast transient response,
internal current limiting, and thermal shutdown protection
of the output devices. The RT9163 is a three-terminal
regulator available in surface mount SOT-89, SOT-223,
and TO-252 packages.
