Automotive 200-mA, low-dropout voltage regulator with enable

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.
