Description

The TPS73633DBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments. Part of the TPS736xx family, it is designed to provide a stable 3.3V output voltage from a higher input voltage with an output current capacity of up to 400mA. It features ultra-low dropout voltage, high power-supply rejection ratio (PSRR), and low quiescent current, making it highly efficient, especially in battery-powered applications.
Key features include a fast start-up time, excellent load and line transient response, and thermal shutdown protection. The device also supports an enable pin for easy on/off control and has an active pull-down circuit to discharge the output capacitor quickly when disabled.
Housed in a small SOT-23-5 package, the TPS73633DBVR is suitable for space-constrained applications such as portable devices and other consumer electronics. It provides precise voltage regulation with a typical accuracy of ±1.5% over temperature, line, and load variations. Overall, this LDO is ideal for applications requiring a reliable and efficient power supply with minimal external components.

Features

The TPS73633DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments, designed to provide a steady 3.3V output. It operates with an input voltage range of 1.7V to 5.5V, making it suitable for a variety of applications. The device features ultra-low dropout voltage, typically around 30mV at 400mA, ensuring efficient performance with minimal power loss.
Key features include a fast transient response and low output noise, important for maintaining stability and performance in sensitive circuits. It also offers current limiting and thermal protection to prevent damage under fault conditions. The regulator is equipped with an active output discharge function, which discharges the output capacitor quickly when the device is disabled.
