The TS1117CP33 RO is a low dropout (LDO) positive voltage regulator from Taiwan Semiconductor. It's designed to provide a stable and regulated 3.3V output voltage from a higher input voltage. The 'RO' suffix typically indicates compliance with RoHS (Restriction of Hazardous Substances) environmental regulations, ensuring it's lead-free and environmentally friendly.

Applications:

• Motherboard power supplies
• Graphic card power supplies
• DVD-Video
• CD-ROM
• Network cards
• Post regulators for switching power supplies

Features:

• Low Dropout Voltage: Typically 1.2V at 1A output current.
• Adjustable Output Voltage: Can be adjusted using external resistors (Note: this part is fixed at 3.3V but the series has adjustable options).
• Output Current of 1A: Suitable for moderate current applications.
• Internal Current Limit: Provides protection against overcurrent conditions.
• Thermal Overload Protection: Shuts down the regulator to prevent damage from excessive heat.
• Reverse Battery Protection
• Available in various packages: Such as SOT-223, TO-252, and TO-220. This specific model is in a CP package.

Benefits:

• Stable Output Voltage: Ensures reliable operation of downstream circuitry.
• Overcurrent Protection: Prevents damage to the regulator and load in case of short circuits or overloads.
• Thermal Protection: Prevents overheating and ensures long-term reliability.
• RoHS Compliant: Meets environmental regulations, making it suitable for a wide range of applications.
• Simple to use: Requires minimal external components.

Additional Details:

The TS1117 series of LDO regulators are commonly used in various electronic devices due to their simplicity and effectiveness. The TS1117CP33 RO specifically provides a fixed 3.3V output, which is a common voltage requirement in many digital circuits and microcontrollers. The CP package is likely a SOT-223 package, which offers good thermal performance in a small footprint. The device is designed for use in applications where a regulated voltage is required and the input voltage is not much higher than the desired output voltage, improving efficiency compared to linear regulators with larger voltage drops.

Typical Specifications:

• Output Voltage: 3.3V
• Output Current: 1A (Maximum)
• Dropout Voltage: 1.2V (Typical at 1A)
• Operating Temperature Range: -40°C to +125°C
• Package: SOT-223 (assumed, based on CP suffix)
