TPS71550DCKRG4 Description

Short technical summary and product information.

The TPS71550DCKRG4 from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for applications requiring low quiescent current and a wide input voltage range. This device can operate with an input voltage from 2.5 V up to 24 V, with a maximum of 30 V for newer chips.

 

It provides a stable output voltage of up to 15 V, with fixed output options available from 1.8 V to 5 V, and an adjustable output from 1.205 V to 15 V. The regulator can supply an output current of up to 50 mA. Key electrical characteristics include a typical quiescent current of 3.2 µA, low noise of 575 µVrms, and a high Power Supply Ripple Rejection (PSRR) of 42 dB at 100 KHz.

 

The TPS71550DCKRG4 is designed for stable operation with a minimum load capacitance of 0.47 µF. It features overcurrent protection for added reliability. The device operates within a junction temperature range of -40°C to +125°C.

 

Packaged in a 5-pin SOT-SC70 (DCK) surface-mount package, this LDO regulator is suitable for space-constrained applications. Its performance characteristics make it a good choice for various power management needs in portable electronics and other systems.
