RT9163
500mA Low Dropout Positive Voltage Regulator
General Description
Features
z Low Dropout, Maximum 1.4V at 500mA
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.
z Fast Transient Response
z
2% Total Output Regulation
z 0.4% Line Regulation
z 0.4% Load Regulation
z TO-92, SOT-89, SOT-223, and TO-252 Packages
z RoHS Compliant and 100% Lead (Pb)-Free
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.
Applications
z 5V to 3.3V Linear Regulator
z Low Voltage Microcontroller, DSP,.... etc. Power Supply
z Linear Regulator for LANCard and CD-ROM

Note 1. Low duty cycle pulse tested with Kelvin connections.
Note 2. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
Note 3. Bandwidth of 10 Hz to 10 kHz.
Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard. The case point of θJC is on the center of the exposed pad.
