The APL5920KAI-TRG is a low dropout regulator (LDO) with an SOP-8P RoHS design, manufactured by Anpec. It is a three-terminal, low-noise, negative voltage regulator with low-dropout voltage and ultra-fast transient response times. The device operates over a wide input voltage range from 3V to 28V and provides an output voltage from -7V to -1V. It features a 0.2 V typical dropout voltage, extremely low quiescent current, and high PSRR of -72 dB at 1 kHz. The operating temperature range is from -40°C to 150°C. The APL5920KAI-TRG is designed to meet the high-density, cost, and performance requirements of consumer, medical, telecom, industrial, and automotive applications.
