STMicroelectronics Voltage Regulators - Linear LD39020ADTPU30R

The LD39020ADTPU30R is a linear voltage regulator IC from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 3.0 V with a maximum output current of 200 mA. It operates with an input voltage range of 1.5 V to 5.5 V and features a low dropout voltage of 200 mV at full load. The device is characterized by a very low quiescent current of 20 ¬µA under no load conditions and less than 0.1 ¬µA in shutdown mode, making it suitable for battery-powered applications. This regulator offers high power supply rejection ratio (PSRR) of 80 dB at 1 kHz and 50 dB at 100 kHz, ensuring stable output voltage under varying load conditions. It includes features such as logic-controlled electronic shutdown, internal soft-start, and optional output voltage discharge. The LD39020ADTPU30R is compatible with ceramic capacitors, specifically requiring a minimum output capacitance of 0.47 ¬µF. It is available in compact DFN4 1x1 and SOT23-5L packages, with an operating temperature range of -40 ¬8C to 125 ¬8C, making it suitable for a variety of applications including mobile phones, tablets, and portable media players.
