TPS73701DCQR 3.3V 1A LDO regulator IC Positive Adjustable 1 Output 1A
The TPS73701DCQR is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with exceptional accuracy and low noise. This compact, low-power LDO is optimized for portable and battery-powered applications, featuring a low quiescent current of typically 1µA in shutdown mode and 85µA during operation. With an input voltage range of 2.2V to 6.5V and a maximum output current of 1A, the TPS73701DCQR provides stable power supply solutions for sensitive analog and digital circuits. Its excellent transient response and low output noise make it ideal for powering RF components, data converters, and microcontrollers in space-constrained designs.
TPS73701DCQR Key Features
The TPS73701DCQR offers outstanding performance with a typical dropout voltage of 210mV at 1A load, ensuring efficient operation even with small input-output differentials. It incorporates advanced protection features including thermal shutdown, current limit, and reverse current protection to enhance system reliability. The device's low output noise (typically 40µVRMS with a 10µF bypass capacitor) makes it particularly suitable for noise-sensitive applications such as audio and precision measurement systems. Additionally, its fast transient response minimizes output voltage fluctuations during sudden load changes, while the enable pin allows for power sequencing and low-power standby modes in battery-operated devices.
TPS73701DCQR Applications
This versatile LDO regulator finds widespread use in portable electronics including smartphones, tablets, and wearable devices where power efficiency and small footprint are critical. It's commonly employed in medical devices such as portable monitors and hearing aids due to its low noise characteristics. The TPS73701DCQR is also extensively used in industrial applications including factory automation equipment, sensor interfaces, and IoT devices. Its ability to maintain stable output under varying load conditions makes it particularly valuable for powering wireless communication modules (Wi-Fi, Bluetooth) and embedded systems requiring clean power supplies.
