Voltage Regulators
A voltage regulator is an electronic device that maintains a constant output voltage level, regardless of changes in the input voltage or load conditions. These devices are commonly used to provide a stable power supply to electronic circuits, as well as to protect them from voltage spikes and surges. There are several types of voltage regulators, including linear, switching, and pulse width modulation (PWM) regulators, each with its own set of characteristics and applications. Linear regulators, for example, are simple and efficient, but have a relatively low switching speed and can only provide a limited output current. Switching regulators, on the other hand, have higher switching speeds and can provide a higher output current, but are more complex and require additional components. In addition to their use in power supplies and voltage protection, voltage regulators are also used in a wide range of other applications, including motor control, battery charging, and instrumentation. Flux.ai has the world's largest community-driven public library of voltage regulators, with footprints, symbols, datasheets, and simulation models for a wide range of devices. Whether you're a designer, engineer, or hobbyist, you can find the resources you need to get your project up and running quickly and efficiently.

Boost Switching Regulator IC Positive Adjustable 2.2V 1 Output 3A SOT-563, SOT-666 TPS61023 device is a synchronous boost converter with 0.5-V ultra-low input voltage. The device provides a power supply solution for portable equipment and smart devices powered by various batteries and super capacitors. The TPS61023 has typical 3.7-A valley switch current limit over full temperature range. With a wide input voltage range of 0.5 V to 5.5 V, the TPS61023 supports super capacitor backup power applications, which may deeply discharge the super capacitor. The TPS61023 operates at 1-MHz switching frequency when the input voltage is above 1.5 V. The switching frequency decreases gradually to 0.5 MHz when the input voltage is below 1.5 V down to 1 V. The TPS61023 enters power-save mode at light load condition to maintain high efficiency over the entire load current range. The TPS61023 consumes a 20- µA quiescent current from VOUT in light load condition. During shutdown, the TPS61023 is completely disconnected from the input power and only consumes a 0.1-µA current to achieve long battery life. The TPS61023 has 5.7-V output overvoltage protection, output short circuit protection, and thermal shutdown protection. • Input voltage range: 0.5 V to 5.5 V • 1.8-V Minimum input voltage for start-up • Output voltage setting range: 2.2 V to 5.5 V • Two 47-mΩ (LS) / 68-mΩ (HS) MOSFETs • 3.7-A Valley switching current limit • 94% Efficiency at VIN = 3.6 V, VOUT = 5 V and IOUT = 1.5 A • 1-MHz Switching frequency when VIN > 1.5 V and 0.5-MHz switching frequency when VIN < 1 V • Typical 0.1-µA shutdown current from VIN and SW • ±2.5% Reference voltage accuracy over –40°C to +125°C • Auto PFM operation mode at light load • Pass-through mode when VIN > VOUT • True disconnection between input and output during shutdown • Output overvoltage and thermal shutdown protections • Output short-circuit protection • 1.2-mm × 1.6-mm SOT563 (DRL) 6-pin package
