TPS70451PWP Description

Short technical summary and product information.

The Texas Instruments TPS70451PWP is a dual-channel, low-dropout (LDO) voltage regulator designed for split-supply applications. It provides independent enable functions and integrated SVS (power-on reset) and power good signals.

 

This regulator family offers flexibility with fixed voltage options such as 3.3V/1.8V, and also supports dual adjustable outputs. Regulator 1 can supply up to 1A, while Regulator 2 supports up to 2A. Key electrical features include ultralow quiescent current of 185µA typical, fast transient response, and low noise output performance without external filter capacitors. It also includes undervoltage lockout (UVLO) and thermal shutdown protection.

 

The TPS70451PWP is housed in a 24-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C, making it suitable for various demanding applications. The device integrates features like a manual reset input and quick output capacitor discharge for system design convenience.
