TPS79330YZQR

The TPS79330YZQR is a high-efficiency, low-noise linear regulator. It provides input voltages ranging from 2.2 V to 5.5 V to an adjustable output voltage. The low 90 mV dropout voltage and the low quiescent current of 1.5 mA, makes the TPS79330YZQR particularly suitable for supplying low-power devices such as sensors, MCUs and ASICs. The regulator is optimized for use in battery-powered applications, including low-power IoT applications.

The output voltage can be set via two external resistors. By choosing an appropriate resistor combination, the output voltage can be accurately adjusted from 0.8 V to 5.0 V in 10 mV increments. The TPS79330YZQR also features a power-good output signal (PGOOD) that signals when the output voltage drops below a preset level. The PGOOD signal can be used to monitor the power supply status of downstream components.

The TPS79330YZQR features an ultra-low quiescent current of 1.5 mA, making it ideal for powering low-power microcontrollers, ASICs, and analog devices. The low quiescent current also means that the TPS79330YZQR can provide a greater amount of power per unit area in comparison to other available regulators.

The TPS79330YZQR operates in dropout mode, meaning that the output voltage is regulated within a certain range when operating from an input voltage lower than the set output voltage. Additionally, the TPS79330YZQR features a low maximum dropout voltage of 90 mV, making it ideal for powering applications that demand a low quiescent current, while providing a high output voltage accuracy.

The TPS79330YZQR is a complete linear regulator, featuring an active-high enable signal (EN) and a low-noise power-control circuit. The EN signal allows the user to enable or disable the regulator. When the regulator is in disable mode, the output voltage is pulled to GND, conserving power and keeping the system shutdown.

The TPS79330YZQR features a low voltage-noise of 1.8 μVRMS, making it suitable for powering a wide variety of analog devices. The low-noise power-control circuit combined with the low input voltage range and the low dropout voltage makes the TPS79330YZQR suitable for powering applications with high-precision requirements, such as medical equipment and analog audio devices.

The TPS79330YZQR is available in a compact SOT23-6 package, making it particularly suitable for portable applications such as wearables, medical systems, and other mobile devices. Additionally, the regulator has an operating temperature range of -40 to +85°C, making it suitable for a wide range of extreme applications.

In summary, the TPS79330YZQR is a high-efficiency, low-noise linear regulator that provides a wide adjustable output voltage range and low quiescent current. It is optimized for use in battery-powered applications, including low-power IoT applications. The TPS79330YZQR is available in a compact SOT23-6 package and can operate over a wide temperature range.
