TPS79101DBVR Description

Short technical summary and product information.

The Texas Instruments TPS79101DBVR is a low-dropout (LDO) linear voltage regulator designed for applications requiring high power supply rejection ratio (PSRR) and ultralow noise. It delivers up to 100 mA of output current and is available in an adjustable output version with a maximum of 5.5V.

 

Key electrical characteristics include ultralow noise of 15 µVRMS and a fast start-up time of 63 µs. The device exhibits a very low dropout voltage, specified as 38 mV at 100 mA for the TPS79147 variant. It also features high PSRR of 70 dB at 10 kHz, making it suitable for noise-sensitive analog circuits.

 

This regulator is stable with any 1-µF ceramic capacitor on the output and offers excellent load and line transient responses. It includes an enable (EN) control feature and protection against over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79101DBVR is supplied in a compact SOT-23-6 package, suitable for surface mount applications. Its low quiescent current (170 µA typical) and very low standby current (less than 1 µA) contribute to power efficiency in battery-powered devices.
