Packaging:
The TLV76050DBZR comes in a SOT-23-5 package, which is a small form-factor, 5-pin surface-mount package.
Pin Function Specifications:
Pin Configuration: Pin Number Pin Name Pin Type Pin Function Description 1 IN Input This is the input voltage pin. Typically, this pin receives a voltage higher than the output voltage (5V) that needs to be regulated. The recommended input voltage range is from 2.3V to 6V. 2 GND Ground Ground pin for the regulator. This pin is connected to the circuit ground. 3 EN Input Enable pin. A logic high on this pin enables the regulator, and a logic low disables it. 4 OUT Output This is the regulated output pin, providing a stable 5V output. 5 NC No Connection Not connected to any internal circuit. It is left floating.Circuit Principle:
TLV76050DBZR works as a Low Dropout Regulator (LDO). It uses an internal transistor (usually a PNP type) to provide regulation. The regulator allows for a small difference (dropout voltage) between input and output, making it efficient for applications with limited headroom. This dropout voltage is very low (approximately 30mV at 100mA output current), which is ideal for battery-powered devices. When the EN pin is high, the regulator allows the input voltage to pass through and adjusts it to a constant 5.0V output (within specified load limits). If the EN pin is low, the regulator is disabled, and the output voltage is zero.Pin Function List (Detailed, in Table Format):
Pin Number Pin Name Pin Type Function Description 1 IN Input Provides the input voltage to the LDO. Must be within the range of 2.3V to 6V for proper regulation. 2 GND Ground Connect this pin to the ground of the system to provide a reference for all voltage levels in the circuit. 3 EN Input Logic input that enables or disables the regulator. A high voltage (above 1.5V) enables the regulator, while a low voltage (below 1.0V) disables the output. 4 OUT Output Delivers the regulated 5.0V output voltage. The regulator maintains a stable 5V under varying load conditions as long as input voltage is within specified range. 5 NC No Connect This pin is not connected internally and can be left unconnected in the circuit.20 FAQ Questions for the TLV76050DBZR:
