The Texas Instruments TLV70033DDCR is a highly reliable, low-dropout regulator (LDO) designed to deliver a fixed output voltage of 3.3V with an input voltage range from 2.0V to 5.5V. This compact LDO is an excellent choice for a wide range of applications, particularly where space and power efficiency are critical considerations.

Key Features

• Output Voltage: Fixed 3.3V with high accuracy.
• Dropout Voltage: Low dropout performance, typically 250 mV at 200 mA load, ensures efficient operation.
• Output Current: Capable of delivering up to 200 mA of continuous output current.
• Power Supply Rejection Ratio (PSRR): Excellent PSRR of 68 dB at 1 kHz helps in maintaining output voltage stability against variations in the input voltage.
• Quiescent Current: Ultra-low quiescent current of 34 µA makes it suitable for battery-powered devices.
• Stability: Stable with low equivalent series resistance (ESR) ceramic capacitors, reducing the amount of required external components.
• Thermal Protection: Built-in thermal shutdown protection safeguards the device from overheating.
• Overcurrent Protection: Current limit feature protects the regulator and the load from damage due to excessive currents.
• Package: Available in a small 5-pin SOT-23 package, ideal for space-constrained applications.
