SN105125DBVR Description

Short technical summary and product information.

The Texas Instruments SN105125DBVR is a versatile low-dropout (LDO) voltage regulator designed for various power management applications. It offers an adjustable output voltage with a tight tolerance of ±2% over its operating range. The device is capable of delivering a continuous load current of up to 150 mA, making it suitable for moderate power requirements.

 

A key feature of the SN105125DBVR is its integrated Power Okay (POK) function, which actively monitors the output voltage and signals system errors with an active-low, open-drain output. This is crucial for system sequencing and fault detection.

 

The regulator is optimized for low noise applications and exhibits a low quiescent current of 150 µA when enabled, and even lower in the off-mode, contributing to power efficiency. It boasts a fast transient response, minimizing voltage overshoot during load transitions. The device requires a small output capacitor for stability and is available in a compact SOT-23 (DBV) package, suitable for surface-mount assembly.

 

Applications for the SN105125DBVR include processor power-up sequencing, palmtop computers, laptops, and notebooks, where stable and reliable voltage regulation is essential.
