## Description

The TPS71718DCKR from Texas Instruments is a low-dropout (LDO) linear voltage regulator offering high power-supply rejection (PSRR) and low quiescent current. This device is suitable for applications demanding clean and stable power.

Key electrical characteristics include an input voltage range of 2.5 V to 6.5 V and a maximum output current of 150 mA. It features a very low dropout voltage of 170 mV typical at 150 mA, and a low noise output of 30 µV RMS typical over a 100 Hz to 100 kHz bandwidth. The PSRR performance is notable, with 70 dB at 1 kHz, 67 dB at 100 kHz, and 45 dB at 1 MHz.

This regulator is available in fixed output voltage versions, with this specific part offering a voltage from 0.9 V to 5 V. The TPS717xx family utilizes an advanced BiCMOS process and a PMOS pass device for fast start-up and excellent transient response. It is stable with a 1-µF ceramic capacitor.

The TPS71718DCKR is housed in a compact 5-pin SOT-SC70 package, measuring 2mm x 2mm, making it ideal for space-constrained designs. The operating temperature range is -40°C to 125°C. It is supplied on tape and reel for automated assembly.
