STMicroelectronics, Inc. LDO Voltage Regulators LD39020DTPU33R

The Fixed LDO Voltage Regulator from STMicroelectronics operates within an input voltage range of 1.5V to 5.5V and provides a maximum output current of 200mA. It features a low dropout voltage of 200mV at full load, making it suitable for applications requiring efficient power management. The device has a very low quiescent current of 20¬µA at no load and can drop to 0.03¬µA in shutdown mode, which is beneficial for battery-powered devices. Output voltage tolerance is ¬±0.5% for the A version and ¬±2.0% at 25¬8C for the standard version. The regulator is designed with high power supply rejection ratio (PSRR) of 80 dB at 1 kHz and 50 dB at 100 kHz, ensuring stable output voltage. It includes features such as logic-controlled electronic shutdown, internal soft-start, and thermal protection. The regulator is compatible with ceramic capacitors, specifically requiring a minimum output capacitance of 0.47¬µF. The product is available in compact DFN4 1x1 and SOT23-5L packages, making it suitable for space-constrained applications such as mobile phones, PDAs, digital cameras, and portable media players. The operating temperature range is from -40¬8C to 125¬8C, which allows for versatility in various environmental conditions.
