The TPS79325DBVR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments (TI). Belonging to the TPS793 series, this device provides a fixed output voltage of 2.5V and supports an output current of up to 200mA. It is designed to deliver stable power for noise-sensitive analog circuits and various electronic applications.
The TPS79325DBVR features a low-noise architecture and high power-supply rejection ratio (PSRR), helping reduce input voltage fluctuations and unwanted power supply noise. These characteristics make it suitable for applications requiring clean and stable voltage regulation, particularly in sensitive analog and RF circuits.
The device integrates an enable control function, allowing external control of the regulator’s operating state. When the enable pin is driven high, the regulator is activated; when driven low, the device enters shutdown mode, helping reduce power consumption in battery-operated electronic systems.
With its low-dropout characteristics, the TPS79325DBVR supports efficient linear voltage regulation while minimizing the voltage difference between input and output. It also provides excellent line and load transient response, helping maintain stable output voltage under changing operating conditions.
The regulator supports an input voltage range starting from 2.7V, subject to sufficient input-to-output voltage headroom, and delivers a fixed 2.5V output. Its continuous output current capability reaches 200mA, making it suitable for low-power voltage regulation and post-regulation applications.
The TPS79325DBVR comes in a compact 5-pin SOT-23 (DBV) surface-mount package, making it suitable for space-constrained PCB layouts and automated surface-mount technology (SMT) assembly.
The device operates across a junction temperature range of -40°C to +125°C, supporting reliable performance in various electronic operating environments.
