TLV70228DSER

TLV70228DSER Application Field and Working Principle

The TLV70228DSER is a single-channel, low-input voltage linear voltage regulator (LDO) used in applications where a low-power, low-dropout, low-noise, positive voltage regulator is required. It is ideal for miniaturized, low-power designs in which the device uses an externally adjustable voltage divider for setting output voltage. This regulator is designed to provide a regulated 7V output from an input voltage of 2.7 to 5.5V.

Features

• Low input voltage range: 2.7V to 5.5V
• Low-noise voltage regulation.
• Low output voltage ripple.
• High output current capability.
• Small footprint: 2mm x 3mm.

Application field

The TLV70228DSER is ideal for providing a regulated 7V output for systems that use small form factor or power-sensitive components. It is suited to a range of applications, such as digital signal processors, microcontrollers, ASICs, electronics control units, and automotive power systems.

Working Principle

The TLV70228DSER operates in the linear region, using the input voltage to create an output voltage lower than the input. This is achieved with the output voltage determined by a voltage divider external to the device. The voltage divider is connected between the output and adjustment pins. When the input voltage rises, the linear regulator compensates by allowing more current to flow through the pass element, thus maintaining regulation.

The TLV70228DSER is designed to provide a regulated 7V output with a maximum output current of 200mA. The device is designed with a low dropout voltage to enable highly efficient power conversion in the power supply. The device also incorporates a voltage trimming feature that enables users to accurately set the output voltage, and it has both an overcurrent protection and thermal shutdown protection to protect itself and the system.
