TL780-15KCSE3 is a series of three-terminal adjustable output regulators, specially designed for mobile and handheld applications. It is a low-dropout (LDO) linear voltage regulator and is capable of delivering up to 1.5A of current. It features an improved power supply rejection ratio (PSRR) for better audio monitoring performance, low quiescent current for longer battery life and integrated current limit for better protection.

Application field

TL780-15KCSE3 extends precise output voltage control and wide input voltage range making it suitable for use in many applications, such as portable communications devices, PDAs, MP3 players, digital cameras, digital video cameras, as well as automotive and medical products. Its low dropout voltage, low quiescent current, stable output voltage in line with the input supply voltage, pulse-by-pulse current limiting, full protection of output short circuit and over-temperature, make it an excellent choice for power supply design.

Working principle

The internal circuitry of the TL780-15KCSE3 is divided into two parts. The first part is the power control module, which includes two stages of regulation. The first stage is the voltage reference module, which supplies a stable and precise reference voltage to the output regulation. The second stage is the current source module, which senses the output voltage, compares it to the reference voltage, and adjusts the current source accordingly. The second part of the regulator is the pulse generation module, which makes sure that each cycle starts with a defined current source applied to the output.

The TL780-15KCSE3 also has built-in thermal protection, which ensures that the regulator will turn off when the junction temperature of the device exceeds a certain predetermined temperature. The product includes a wide range of features, such as output voltage tracking, power-on reset, current limit, and low dropout voltage.

Overall, the TL780-15KCSE3 is an ideal choice for applications requiring a low dropout regulator with stable output voltage and wide input voltage range. Its low-dropout voltage and wide input voltage range make it suitable for applications running on a single cell (2V-6V) or double cell (4V-12V) battery.
