This low-voltage regulator offers a wide range of features, including a low quiescent current operation, low dropout voltage and a high accuracy reference voltage. This application field and working principle of the S80155ANPF-JDGTF G are described in the following sections.

Application Field

The S-80155ANPF-JDGTFG is suitable for a variety of applications, including systems where high load current must be regulated at a low voltage or a current-balancing regulator is required. It features a low quiescent current of 2.5μA and also provides a fast transient response of 1 µs. It also includes three outputs with selectable current limit, thermal regulation, and over temperature protection. This low-voltage regulator is especially ideal for consumer audio, cellular phone and battery-powered applications, as well as automotive products and Bluetooth product segments.

Working Principle

The operation of the S-80155ANPF-JDGTFG is based on a low dropout (LDO) regulator principle. The regulator uses a low external input supply voltage and a higher output voltage to create a voltage differential (ΔV) between the two. When the output voltage increases, the delta voltage increases and this causes the output current to rise. The LDO regulator also has a reference voltage, which is applied to the control circuit in order to ensure that the output voltage is calibrated accurately. This reference voltage is monitored by the feedback circuit and the regulator\'s output is adjusted accordingly. The S-80155ANPF-JDGTFG has a high accuracy reference voltage, which allows for better regulation at varying temperatures. The output current is determined by the external load, as well as the current limit and thermal regulation.

The LDO regulator also has an adjustable voltage range and a built-in current limiter designed to provide protection against over current conditions. The S-80155ANPF-JDGTFG also has over temperature protection and a power good output that indicates a negative voltage applied to the output. This feature is useful for fault diagnosis and system protection.

The S-80155ANPF-JDGTFG is available in a variety of packages such as SOT-23-6, FSQP-25 and PQFN-20 that provide a minimum footprint and options for optimized thermal performance. This regulator has a very low quiescent current, which extends the battery life in power management applications. Along with its wide voltage input range and low dropout voltage, the S-80155ANPF-JDGTFG is ideal for a variety of applications such as consumer audio, cellular phones, and battery-powered applications.

The S-80155ANPF-JGDMG is categorized as a PMIC (Power Management Integrated Circuit) Supervisor due to its wide range of features and functions. This low dropout regulator is designed to offer a low quiescent current, high accuracy reference voltage, fast transient response, adjustable voltage range, and built-in current limiters. Its wide selection of packages also allow for improved thermal performance in a variety of applications.
