RT9165 - Richtek

RT9165
150mA 3-Terminal Positive Regulator
General Description
Features
The RT9165 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 5.0V or 8.0V. The RT9165 provides excellent
regulation over line, load, and temperature variations.

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