The TPS793-Q1 is a low-dropout (LDO), low-power, linear voltage regulator. This device features high power-supply rejection ratio (PSRR), ultra-low noise, fast start-up, and excellent line and load transient response. The TPS793-Q1 is available in small-outline SOT-23 packages that sources 200mA.

The TPS793-Q1 is designed for post-regulation applications, offering fixed and adjustable options supporting common voltage rails like 3.3V. The low noise and PSRR performance makes the device designed for power-sensitive analog loads.

The TPS793-Q1 offers foldback current limit to reduce power dissipation during overcurrent condition. The EN input helps with power-sequencing requirements of the system. The internal soft-start provides a controlled start-up, reducing inrush current and allowing lower input capacitance to be used.
