The AP2121N-3.0TRG1 from Diodes Incorporated is a high-speed, extremely low-noise LDO regulator IC. It provides a fixed 3V output voltage and can deliver up to 200mA of current, with a limit of 300mA. This device is fabricated using a CMOS process and includes features such as a voltage reference, error amplifier, and current limit circuit.
Key electrical characteristics include a low dropout voltage of 150mV typical at 100mA, low standby current of 0.1µA typical, and low quiescent current of 25µA typical. It boasts high ripple rejection of 70dB typical at 1kHz and high output voltage accuracy of ±2%. The regulator is designed for battery-powered devices and offers excellent line and load regulation.
This component is supplied in a SOT-23-3 surface mount package. It is compatible with low ESR ceramic capacitors as low as 1µF. The operating temperature range is -40°C to 85°C. Note that this part is not recommended for new designs; AP7343 is suggested as a replacement.
