The APL5326BI-TRG is a SOT-23-5 RoHS Low Dropout Regulator (LDO) manufactured by Anpec. This part features a 5V input voltage, and offers external sensing feature for error correction and positive temperature coefficient (PTC) for output short-circuit protection. It also boasts a low dropout voltage of 160mV at 200mA load current, a fast transient response, and a maximum input-output voltage differential of 4V. With low quiescent current (15uA), high PSRR 80dB, and low output noise, this part is designed for low power applications where excellent regulation and efficiency, minimal temperature rise, and low cost are key requirements.
