What are the primary applications for this LDO?

It is ideal for noise-sensitive analog circuitry, including op-amps, ADCs, DACs, audio systems, and post-DC-DC converter ripple filtering.

What are the key electrical specifications?

It supports an input range of 3V to 36V, adjustable output from 1.194V to 33V, 150mA output current, and 15.4 µVRMS noise performance.

What should engineers consider regarding thermal design?

The device uses an HVSSOP PowerPAD package. The thermal pad must be soldered to the PCB ground plane to ensure effective heat dissipation and prevent thermal shutdown.

What is the sourcing status of this component?

The part is currently active and widely available, with no significant supply chain risks reported.
