The ZRC400F01TA is an adjustable low-dropout voltage regulator with low output impedance. It is specifically designed for applications that require precise regulation over a wide range of conditions. This device is a member of the ZRC series of advanced active voltage regulators, designed to provide voltage references with HVM (High Voltage Maintenance) functionality.

The ZRC400F01TA regulator provides precision programmable or fixed output voltages ranging from 0.8V to 3.3V and up to 4A. It features high efficiency, low noise, low dropout, frequency and temperature compensation, active current limit and short circuit protection and overvoltage protection.

The ZRC400F01TA is suitable for a wide range of applications, including portable electronic products, noise-sensitive applications, battery-powered products, industrial and automotive applications. These applications include DC-DC converters, charge pumps, power supplies and precision analog and bias circuitry.

The ZRC400F01TA operates in one of two modes. In the ‘normal mode’, the device acts as a conventional low-dropout voltage regulator providing a regulated voltage. In the ‘active mode’, the ZRC400F01TA can be used as a programmable reference source with Internal HVM, active current-limit and Active Voltage Clamp (AVC) circuit. The AVC circuit not only limits the maximum output voltage of the regulator, but also effectively reduces its output impedance to control voltage droop due to load current changes.

The ZRC400F01TA is designed to be easy to use and the use of external components is minimized. It incorporates an on-chip voltage reference and voltage adjust circuit. The reference voltage has a temperature coefficient of less than ±50ppm/°C, providing precise output voltage regulation even across wide temperature ranges. The low output noise of the ZRC400F01TA allows for a clean power supply for use in noise sensitive applications.

In summary, the ZRC400F01TA is an adjustable low-dropout voltage regulator with low output impedance. It is specifically designed for applications that require precise regulation over a wide range of conditions. It can accurately regulate voltage from 0.8V to 3.3V, and offers high efficiency, low noise and low dropout. It also offers frequency and temperature compensation, active current limit, short-circuit protection, overvoltage protection and HVM (High Voltage Maintenance) functionality. It is suitable for a wide range of applications where precise voltage regulation is required, including portables, noise-sensitive applications, battery-powered products and industrial and automotive applications.
