Product details

2.8 V fixed LDO for noise-sensitive rails

The SOT-23-5 footprint is a standard low-profile surface-mount package. The -40°C to 125°C operating range covers automotive under-hood and industrial motor-drive environments.

Dropout and quiescent current — the real-world margins

Maximum dropout is 0.58 V at the full 150 mA load. Quiescent current sits at 95 µA typical. The 16 V maximum input voltage lets this LDO survive load-dump transients. Over-current, over-temperature, and short-circuit protection are built in.

Lifecycle and sourcing

The LP2985-28DBVR carries an Active product status per the manufacturer. It is ROHS3 compliant. No last-time-buy or end-of-life notice is in effect.

Frequently asked questions

What is LP2985-28DBVR's listed PSRR?

PSRR is 45 dB at 1 kHz. This is the figure for the fixed-output version and is adequate for filtering switching-regulator ripple on a 2.8 V analog supply rail.

What is the closest pin-compatible alternative to LP2985-28DBVR?

Within the LP2985 family, the fixed-output voltage variants (e.g., LP2985-33DBVR for 3.3 V) share the same SOT-23-5 pinout and enable logic. For a different output voltage at the same 150 mA rating, the corresponding LP2985-xxDBVR is a drop-in replacement.
