The LP38693SD-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, delivering a fixed 3.3V output with a maximum output current of 500mA. It operates over an input voltage range of 2.7V to 10V, making it suitable for battery-powered and other low-voltage applications. The device features a typical dropout voltage of only 250mV at full load, ensuring efficient regulation even with small headroom.
Key electrical characteristics include a low quiescent current of 55µA (typical) at full load, reducing to 1µA in off-state, which helps extend battery life. The regulator offers a power supply rejection ratio (PSRR) of 55dB at 120Hz and 50dB at 100kHz, providing good noise filtering. Output accuracy is typically 2% at 25°C, and the output noise is 80µVrms. Protection features include over-temperature shutdown, and an enable pin allows for on/off control.
The LP38693SD-3.3/NOPB is available in a 6-WSON (3x3) package as well as a 6-WDFN exposed pad package, both surface-mount. It requires a minimum load capacitance of 1µF for stability. The device is specified for operating temperatures from -40°C to 125°C, making it suitable for industrial and automotive environments.
