RT2517B
Operation
The RT2517B is a linear regulator designed specially for
ultra-low dropout voltage. The input voltage range is from
2.2V to 6V.
Output Transistor
The RT2517B builds in a MOSFET output transistor which
provides a low switch-on resistance for low dropout voltage
applications.
Error Amplifier
The Error Amplifier compares the internal reference voltage
with the output feedback voltage from the internal divider,
and controls the Gate voltage of MOSFET to support good
line regulation and load regulation at output voltage.
Current Limit
The RT2517B provides current limit function to prevent
the device from damages during over-load or short-circuit
condition. This current is detected by an internal sensing
device
Reference Generator
The RT2517B provides a reference voltage by internal
reference generator circuit. The reference voltage can be
used to determine the output voltage.
Thermal Shutdown
The thermal shutdown function will turn off the MOSFET
when the junction temperature exceeds 160°C (typ.).
Once the junction temperature cools down by
approximately 10°C, the regulator will automatically
resume operation.
