Description

The TLV70450DBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to provide a fixed output voltage of 5.0V. It is part of the TLV704 series, which is known for its low quiescent current and high power supply rejection ratio (PSRR), making it suitable for battery-powered and noise-sensitive applications.
The device features a maximum output current of 150 mA and has a dropout voltage of approximately 665 mV at full load. One of its key advantages is its ultra-low quiescent current, typically around 3.2 µA, which helps extend battery life in portable devices. The TLV70450DBVR also includes an integrated over-current protection mechanism and thermal shutdown to prevent damage from excessive heat.
This voltage regulator comes in a small SOT-23-5 package, making it ideal for space-constrained applications. It operates over a wide input voltage range, typically from 2.5V to 24V, and has an operating temperature range from -40°C to 125°C, ensuring reliable performance in various environmental conditions.

Package

The TLV70450DBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments. It comes in a SOT-23-5 package, which is a small-outline transistor package with five pins, suitable for compact circuit designs.

Pinout

The TLV70450DBVR is a low-dropout (LDO) voltage regulator from Texas Instruments. It is housed in a 5-pin SOT-23 package. The key functions of each pin are:
1. Input (IN): This pin is for the input voltage, which needs to be higher than the desired output voltage to ensure proper regulation.

2. Ground (GND): This pin is the ground connection for the device, providing a common reference point for the input and output voltages.
3. Output (OUT): This pin delivers the regulated output voltage. For the TLV70450DBVR, it is a fixed 5.0V output.
4. Enable (EN): This pin is used to enable or disable the regulator. A high voltage level at this pin enables the output, whereas a low voltage level disables it.
5. No Connect (NC): This pin is typically not connected internally. It may not be present in all versions of the SOT-23-5 package or might be used for mechanical stability.
The TLV70450DBVR is designed for low-power applications, offering excellent line and load transient performance, making it ideal for battery-powered devices.
