Description

The TPS766 is a low-dropout (LDO) linear voltage

regulator that supports an input voltage range from

2.5V to 16V (new chip) and up to 250mA of load

current. For the new chip, the supported output range

is from 1.2V to 12V (fixed version) or from 0.8V to

14.6V (adjustable version).

The input voltage range is up to 16V (new chip),

which makes the device a good choice for operating

from transformer secondary windings and regulated

rails (such as 10V or 12V). Additionally, the wide

output voltage range allows the device to generate

the bias voltage for silicon carbide (SiC) gate drivers

and microphones, as well as power microcontrollers

(MCUs) and processors.

Wide bandwidth PSRR performance is greater than

70dB at 1kHz and 46dB at 1MHz (new chip),

which helps attenuate the switching frequency of

an upstream DC/DC converter and minimizes post

regulator filtering. The new chip supports internal

soft-start circuit mechanism that reduces inrush

current during start-up, thus allowing for smaller input

capacitance.

The legacy chip supports constant quiescent current

across the complete load current range (typically

35μA for the full range of output current, 0mA to

250mA).
