Description
General part information
TPS77028 Series
The TPS770 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.
