Low dropout linear regulators (LDOs) can be used in applications which require to drop a higher input voltage to a lower output voltage at relatively moderate power levels. Richtek has developed a broad portfolio of LDOs which feature high power supply ripple rejection (PSRR) to keep the output voltage free of noise and ripple, low quiescent current (Iq) to extend battery life and different packaging for various power dissipation. The wide input-voltage LDOs operating in wide temperature rating can be applied in industrial applications. The high-performance AEC-Q100 qualified LDOs are ideal for automotive applications.

Offering single output regulators with a Vin ≤ 6.5V.
Offering both dual output regulators with a Vin ≤ 5.5V and multiple output linear regulator controllers.
Vin ≤ 80V for applications requiring wide input range and high input voltage.
For applications requiring long standby time and running in burst mode conditions.
For noise-sensitive system to filter out input ripple and provide low noise/high PSRR at the output.
The AEC-Q100 qualified LDOs and LDOs operating in wide temperature ratings are ideal for automotive and industrial applications.
