概述

Description

The TLV70028DDCR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for applications requiring low power and high performance. This regulator provides a fixed output voltage of 2.8V, making it suitable for powering a wide range of electronic devices and circuits. With a typical dropout voltage of 200mV at full load, it ensures efficient power conversion, even when the input voltage is close to the output voltage.
The TLV70028DDCR supports an input voltage range from 2V to 5.5V, making it versatile for use with different power sources. It features a low quiescent current of approximately 31µA, which helps in minimizing power consumption, making it ideal for battery-powered applications. The device also includes thermal shutdown and current limit protection, safeguarding it against overheating and overcurrent conditions.
Its small SOT-23-5 package and minimal external component requirements make it easy to integrate into compact designs. Common applications include portable electronics, wireless devices, and other systems requiring reliable voltage regulation with minimal energy wastage.

Package

The TLV70028DDCR is a voltage regulator that comes in a surface-mount SOT-23-5 package. This package type is compact, making it suitable for space-constrained applications.

Pinout

The TLV70028DDCR is a low-dropout linear voltage regulator. It comes in a 5-pin SOT-23 (DDC) package. Here are the pin functions:
1. IN: This is the input voltage pin. It connects to the supply voltage and supports a wide input voltage range.
2. GND: This pin is connected to ground.
3. EN: The enable pin allows the regulator to be turned on or off. Pulling this pin high enables the regulator, while pulling it low disables it.
4. OUT: This is the output voltage pin, which provides the regulated voltage output. For the TLV70028, the output is a fixed 2.8V.
5. NC (No Connect): This pin is not internally connected and can be left floating or connected to ground for improved thermal performance.
The TLV70028 is designed for low quiescent current and fast transient response, making it suitable for battery-powered applications.
