Texas Instruments Voltage Regulators - Linear TPS73601DCQR

The TPS73601DCQR is a linear voltage regulator from Quarktwin Technology Ltd. designed for applications requiring a stable output voltage with low dropout. It features an input voltage range of 1.7 V to 5.5 V and can deliver up to 400 mA of output current. The device operates with an ultra-low dropout voltage of 75 mV typical at full load, making it suitable for battery-powered applications. This regulator is notable for its stability without the need for an output capacitor, which simplifies design and reduces component count. It also provides excellent load transient response and low output noise, measured at 30 OºV RMS from 10 Hz to 100 kHz, making it ideal for noise-sensitive applications such as voltage-controlled oscillators (VCOs). The TPS73601DCQR includes built-in protection features such as thermal shutdown and current limit, ensuring reliable operation under various conditions. It is available in a compact SOT-223 package, suitable for space-constrained designs. The device is rated for operation over a temperature range of -40¬8C to 125¬8C, making it versatile for different environmental conditions.
