Product details

PSRR bandwidth and what it buys you

PSRR is specified at 65dB at 100Hz, rolling to 40dB at 1MHz.

Protection set and temperature range

Over-current, over-temperature, and under-voltage lockout are all on-die. The operating junction temperature range of -40°C to 125°C covers automotive under-hood and industrial motor-drive environments. Enable and soft-start control are available for sequencing; the soft-start limits inrush into capacitive loads on power-up.

Package and footprint

Housed in a SOT-23-5 package, surface-mount only.

Lifecycle and sourcing

No last-time-buy or obsolescence notice is in effect — it is a current-design-in part. For BOM planning, this means no near-term end-of-life risk and continued factory support.
