100-mA, 10-V, low-IQ, low-dropout voltage regulator with enable

The TPS769

is a low-dropout (LDO) linear voltage regulator. This device supports an input

voltage range from 2.5V to 16V (new chip) and up to 100mA of load current. For the

new chip, the supported output range is from 1.2V to 5.0V (fixed version) or from

1.2V to 5.5V (adjustable version).

The wide input voltage range makes the

device a good choice for operating from regulated rails (such as 10V or 12V). The

voltage range is up to 16V for the new chip. This range allows the LDO to generate

the bias voltage for a variety of applications. These applications include power

microcontrollers (MCUs) and processors.

Wide bandwidth PSRR performance is

greater than 70dB at 1kHz and 46dB at 1MHz (new chip). This performance helps

attenuate the switching frequency of an upstream DC/DC converter and minimizes post

regulator filtering. The new chip supports an internal soft-start circuit mechanism

that reduces inrush current during start-up, thus allowing for smaller input

capacitance.
