TPS79942DDCR Description

Short technical summary and product information.

The Texas Instruments TPS79942DDCR is a low-dropout (LDO) linear voltage regulator designed for efficient power management. It provides a fixed output voltage of 4.2V and can supply up to 200mA of current.

 

Key electrical characteristics include a low quiescent current of 40µA, a very low dropout voltage of 100mV typical (160mV max at 200mA), and high power-supply rejection ratio (PSRR) of 66dB at 1kHz. The regulator also features over current, over temperature, reverse polarity, and under voltage lockout protection, along with an enable control.

 

This device is supplied in a compact SOT-23-5 Thin package, suitable for surface mounting. The operating temperature range is -40°C to 125°C. Its stable performance with low-ESR output capacitance and excellent transient response make it suitable for various electronic applications requiring a stable and low-noise power supply.
