LP5900SD-3.3 Description

Short technical summary and product information.

The Texas Instruments LP5900SD-3.3 is a linear, low-dropout (LDO) voltage regulator designed for applications requiring low noise and low quiescent current. It operates with an input voltage range of 2.5 V to 5.5 V and can deliver up to 150 mA of output current.

 

This LDO regulator features a low output voltage noise of 6.5 µVrms and high PSRR of 40 dB at 100 KHz, making it suitable for sensitive RF and analog circuits. It offers various fixed output voltage options from 1.5 V to 4.5 V with a typical accuracy of ±2% and a low dropout voltage of 80 mV typical.

 

The LP5900SD-3.3 includes a logic-controlled enable pin for power management, along with thermal-overload and short-circuit protection for reliability. It is designed to be stable with a minimum load capacitance of 0.47 µF and does not require a bypass capacitor for noise reduction. The device operates over a junction temperature range of -40°C to 125°C and is available in DSBGA and WSON packages.
