The Texas Instruments LP38798SD-ADJ is a high-performance, adjustable low-dropout (LDO) voltage regulator capable of supplying up to 800 mA of output current. Designed with sensitive RF and analog circuitry in mind, this LDO regulator utilizes an advanced CMOS process to achieve ultra-low output noise and high power supply rejection ratio (PSRR).
Key electrical specifications include a wide operating input voltage range of 3 V to 20 V, with an output voltage adjustable from 1.2 V to 19.8 V. It boasts very low dropout voltage (typically 200 mV at 800 mA) and maintains ±1% initial accuracy at 25°C. The device exhibits ultra-low output noise of 5 µV RMS (10 Hz to 100 kHz) and high PSRR, with 90 dB at 10 kHz and 60 dB at 100 kHz.
This regulator is stable with ceramic or tantalum output capacitors and offers excellent line and load transient response. It also includes integrated current limit and overtemperature protection features. The LP38798SD-ADJ is supplied in a 16 mm² WSON (DNT) package, suitable for surface mounting.
It operates within a temperature range of -40°C to 125°C.
