S-1132B32-I6T2G Description

The S-1132B32-I6T2G is a linear regulator IC designed for efficient power management, featuring a fixed output voltage of 3.2V and a maximum output current of 300mA. Manufactured by ABLIC Inc., this device is part of the Power Management IC (PMIC) category and is housed in a Surface Mount package, specifically the SNT6A form factor. Despite its small size, the S-1132B32-I6T2G offers robust performance and a range of features that make it suitable for various applications.

S-1132B32-I6T2G Features

The S-1132B32-I6T2G is designed to provide stable power regulation with a fixed output voltage of 3.2V, ensuring consistent performance across a wide range of input voltages up to 6.5V. Its low quiescent current of just 1µA and a maximum supply current of 40µA make it highly efficient, minimizing power consumption even under no-load conditions.

One of its key features is the low dropout voltage of 0.19V at 100mA, which allows the regulator to maintain its output voltage even when the input voltage is close to the output voltage. This is particularly useful in battery-powered applications where the input voltage may drop significantly as the battery discharges.

The regulator also includes an enable control feature, providing additional flexibility in power management. It offers over-current protection, ensuring the safety of the device and connected circuits under fault conditions. The Power Supply Rejection Ratio (PSRR) of 65dB at 1kHz further enhances the regulator's ability to filter out noise from the input power supply, resulting in cleaner output voltage.

S-1132B32-I6T2G Applications

The S-1132B32-I6T2G is ideal for a variety of applications requiring stable and efficient power regulation. Its low dropout voltage and high PSRR make it suitable for battery-powered devices, such as portable electronics, where maintaining a stable output voltage is crucial as the battery voltage decreases.

The enable control feature and low quiescent current are particularly beneficial in applications where power consumption needs to be minimized, such as in standby modes or low-power sensors. The over-current protection ensures reliability and longevity, making it a reliable choice for consumer electronics, medical devices, and industrial control systems.
