TPS73619DRBR - Texas Instruments

The TPS73619DRBR is a highly reliable, low-dropout (LDO) voltage regulator from the renowned semiconductor manufacturer, Texas Instruments. This device is designed to provide a fixed output voltage of 1.9V with an impressive accuracy of ±1%. The regulator can supply up to 400mA of output current, making it suitable for a wide range of applications including power-sensitive RF/analogue circuits, portable devices, and post-regulation for switching power supplies.

One of the key features of the TPS73619DRBR is its low dropout voltage, which enhances efficiency by allowing operation closer to the battery end-of-life in battery-powered applications. This characteristic is particularly important for maintaining performance as the input voltage approaches the output voltage level.

The device is offered in a compact 3x3 mm2 SON-8 package, identified by its orderable part number TPS73619DRBR, which is ideal for space-constrained applications. The small form factor does not compromise its thermal performance, as it is designed to dissipate heat effectively, ensuring reliable operation over its entire temperature range.

Additionally, the TPS73619DRBR features a low quiescent current, which is a critical parameter for battery-powered devices, as it extends battery life by reducing the power consumed when the device is in standby mode. It also includes over-current and over-temperature protection circuits, which safeguard the device and the load from damage due to abnormal operating conditions.

Moreover, the TPS73619DRBR supports stable operation with ceramic capacitors, which are preferred in modern electronic designs due to their small size, reliability, and low equivalent series resistance (ESR). This compatibility allows for a cost-effective and compact power supply design.

For design flexibility, the TPS73619DRBR provides an enable pin that allows the user to turn the output on and off, offering additional power-saving opportunities by shutting down the regulator when it's not needed. The device's performance is characterized for operation over the full industrial temperature range of -40°C to +125°C, which makes it suitable for industrial and automotive applications.

In summary, the TPS73619DRBR from Texas Instruments is a versatile LDO voltage regulator that combines high accuracy, low dropout, and low quiescent current with robust protection features, making it an excellent choice for a wide array of power management applications.
