LP38693MP-3.3 Description

Short technical summary and product information.

The Texas Instruments LP38693MP-3.3 is a high-performance, 500mA low-dropout (LDO) linear voltage regulator designed for various applications. It provides a stable, fixed 3.3V output voltage from an input range of 2.7V to 10V.

 

Key electrical specifications include a low dropout voltage of 250mV at 500mA, typical quiescent current of 55µA at full load, and an off-state quiescent current of 1µA. The regulator offers noise reduction with 80µVrms noise and 50dB PSRR at 100 KHz. Protection features include thermal overload protection and foldback current limiting.

 

This device is supplied in a SOT-223-5 surface-mount package, suitable for space-constrained designs. The operating temperature range is -40°C to 125°C, ensuring reliable performance in demanding environments. It requires a minimum load capacitance of 1µF for stability with ceramic output capacitors.
