TLV70033DDCR Detailed explanation of pin function specifications and circuit principle instructions

The TLV70033DDCR is a part from Texas Instruments (TI), which is a popular semiconductor brand. The model corresponds to a low-voltage, low-dropout (LDO) linear voltage regulator, specifically designed for efficient Power supply applications.

Package Type:

The TLV70033DDCR comes in a 5-pin SOT-23 package.

Here’s the detailed pin function description for the 5-pin configuration:

Pin No. Pin Name Pin Function Description 1 IN Input: This pin is used to connect the input voltage to the LDO regulator. It must be higher than the output voltage by at least the dropout voltage of the LDO for proper regulation. 2 GND Ground: This pin is the reference ground for the LDO regulator circuit. All signals and voltages are referenced to this ground. 3 EN (Enable) Enable: This pin is used to enable or disable the LDO regulator. A logic high signal on this pin turns the regulator on, while a logic low signal disables it (puts it in a low-power shutdown mode). 4 OUT Output: This pin provides the regulated output voltage. The LDO regulator maintains a stable voltage at this pin as long as the input voltage is within the required range. 5 NC No Connect: This pin is not connected internally and is typically not used in the application. It is included in the package for mechanical reasons.

Functionality Overview:

Input Voltage (IN): The input voltage must be greater than the desired output voltage by at least the LDO’s dropout voltage for the regulator to function properly. Ground (GND): This is the reference for all voltages and must be connected to the ground of the system. Enable Pin (EN): When the EN pin is driven high (logic high level), the regulator is enabled and starts to output a regulated voltage. If driven low, the device is in a shutdown state, consuming negligible current. Output (OUT): This pin outputs the regulated voltage. The regulation is tight, with low dropout voltage for efficient operation even when the input voltage is close to the output voltage. No Connect (NC): Not connected internally to any circuit, so it can be left unconnected in the application.
