Product details

Adjustable LDO for noise-sensitive rails

The Texas Instruments TPS73401DDCT is a single-output positive adjustable LDO regulator delivering up to 250 mA. Output voltage sets from 1.25 V to 6.2 V via external resistor divider.

Dropout and PSRR — what they mean for the rail budget

Dropout of 0.22 V maximum at 250 mA is a worst-case figure; at lower loads it is proportionally smaller.

Lifecycle and sourcing

The TPS73401DDCT carries an Active product status from Texas Instruments, with ROHS3 compliance. No last-time-buy or discontinuation notice is in effect.
