The AP2121AK-3.3TRE1 is a positive voltage regulator IC from Diodes Incorporated, fabricated using a CMOS process. It is designed for high-speed, extremely low-noise applications, making it suitable for various battery-powered devices.
Key electrical characteristics include a 3.3V fixed output voltage, a maximum output current of 200mA, and a low dropout voltage of 150mV typical at 100mA. It features high ripple rejection of 70dB at 1kHz, excellent line and load regulation, and high output voltage accuracy of ±2%. The device also boasts extremely low noise of 30µVrms from 10Hz to 100kHz and a low quiescent current of 25µA typical.
This LDO regulator is available in a SOT-23-5 package, suitable for surface mount (SMD/SMT) applications. It operates within a temperature range of -40°C to +85°C. The datasheet notes that the AP2121 series is not recommended for new designs, with the AP7343 suggested as a replacement.
Applications for this regulator include mobile phones, wireless communication equipment, portable games, cameras, and sub-board power supplies for telecom equipment.
