PSRR is specified at 65dB at 100Hz, rolling to 40dB at 1MHz.
Over-current, over-temperature, and under-voltage lockout are all on-die. Enable and soft-start control are available for sequencing; the soft-start limits inrush into capacitive loads on power-up.
Housed in a SOT-23-5 package, surface-mount only.
