1. Package Type
The part number TLV1117LV33DCYR is in the SOT-223 package. This is a surface-mount package commonly used for power devices such as voltage regulators.
2. Pin Function and Specifications
The TLV1117LV33DCYR has 3 pins, which are:
Pin Number Pin Name Pin Function Description 1 IN Input Voltage (V_in) – This pin connects to the unregulated input voltage. It must be greater than the output voltage by at least the dropout voltage. 2 GND Ground – This pin connects to the ground of the system. It provides the return path for current. 3 OUT Output Voltage (V_out) – This pin provides the regulated output voltage (typically 3.3V for this model). Circuit Principle and Function: The TLV1117LV33DCYR operates by providing a fixed output of 3.3V (for the "33" variant), which is regulated from a higher input voltage. The device uses a low dropout regulator mechanism, which allows it to maintain regulation even when the input voltage is close to the output voltage. The input voltage typically needs to be at least 3.5V to ensure proper regulation, but the device works with a minimal difference between input and output due to its low dropout characteristic.3.
