简单介绍
The RT9182 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators.
Performance features of the series includes low output noise, high ripple rejection ratio, low dropout and
very fast turn-on times.
The RT9182 includes a reference voltage source, error amplifiers, driver transistors, current
limiters and phase compensators internally. The RT9182’s current limiter’s foldback circuit also
operates as a short protect for the output current limiter. The output voltage for each regulator is set
independently by laser trimming. Voltages are selectable in 50mV steps within a range of 1.3V to 5.0V.
The EN function allows the output of each regulator to be turned off independently, resulting in
greatly reduced power consumption. The RT9182 series is available in the SOT-26.
