TPS78633 Description

Short technical summary and product information.

The Texas Instruments TPS78633 is a high-performance, 1.5-A low-dropout linear voltage regulator designed for demanding applications. It provides a stable output voltage with ultralow noise and high Power Supply Rejection Ratio (PSRR), making it suitable for sensitive RF circuits, ADCs, and audio components.

 

Key electrical specifications include an input voltage range of 2.7 V to 5.5 V and an output voltage range from 1.22 V to 5.2 V, with fixed output options available. The regulator boasts a typical dropout voltage of 390 mV at full load and a quiescent current of 0.26 mA. It features an enable pin for power sequencing and a soft-start function to minimize inrush current.

 

This LDO regulator is designed for stability with a minimum load capacitance of 1 µF and offers excellent load and line transient response. It operates across a wide temperature range of -40°C to 125°C. The TPS78633 is available in multiple package options including SOT-223, VSON, and TO-263, supporting surface mount applications.

 

Applications for the TPS78633 include RF systems such as VCOs and receivers, audio circuits, Bluetooth and wireless LAN modules, cellular phones, and handheld organizers. Its combination of low noise, high PSRR, and robust performance makes it a versatile choice for power management in various electronic devices.
