RICHTEK RT9163-35PG

RT9163
500mA Low Dropout Positive Voltage Regulator
General Description
Features
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.

(Note 3)
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.
