The S-1132B30-I6T2U is a Linear Regulator from the PMIC (Power Management Integrated Circuit) Voltage Regulators range. It is a compact, low dropout voltage regulator designed for efficient power supply solutions and improved power stability. It is suitable for a range of applications including automotive, industrial, and consumer electronics. The device offers selectable 3.2V, 3.3V, 3.4V, or 3.6V outputs, with current up to 1.5A. It can operate from an input voltage range of 2.5V to 5.5V. The S-1132B30-I6T2U regulator is based on a current mode, voltage feedback topology, which offers high switching frequency, tiny solution size, and fast transient response.

The S-1132B30-I6T2U is a high-efficiency, low-noise and high-PSRR regulator. It includes temperature protection and soft start circuitry which limits in rush current during turn on. The device boasts performance indicators such as a 0.5V dropout voltage, 20 mV typical output voltage accuracy, and up to 88.5% efficiency. It provides excellent protection features such as short-circuit protection (SCP) and under-voltage lockout (UVLO). It is available in a tiny SIP (Super-Small-Package) with an exposed back side thermal pad for increased surface area for improved heat dissipation.

The S-1132B30-I6T2U is an ideal device for low-noise, low dropout voltage regulation, current limiting, and thermal protection. With its wide input voltage range, it is suitable for a range of applications such as automotive and industrial power supplies, computing devices, and point-of-load power supplies. It is also well suited for CCTV, multimedia player systems, mini fan and control systems, as well as a host of other general purpose digital and RF/communications devices.

The S-1132B30-I6T2U voltage regulator operates in a simple configuration, using an internal reference voltage, an error amplifier, a P-channel MOSFET and a N-channel MOSFET connected to an adjustable feedback resistor and an adjustable current sharing resistor. When an input voltage is applied to the device, the current sharing resistor set to some constant value, along with the internal reference voltage, determines the output voltage. The voltage at the P-channel MOSFET determines the output voltage. When the output voltage rises, the voltage at the error amplifier also rises. As this voltage increases, the error amplifier responds by reducing the gate voltage at the P-channel MOSFET, which in turn adjusts the output voltage to remain within the set voltage range. In this way, the error amplifier serves to control the output voltage.

To ensure accuracy and stability, the S-1132B30-I6T2U regulator also includes an adjustable Soft-Start circuit and Under Voltage Lockout (UVLO), which prevents the start-up of the regulator in an undersupplied condition. In addition, the device provides an open loop current limit protection feature to protect the device from an over current condition. The device also features Automatic Shutdown, which turns off the output MOSFET when the output is shorted or overloaded.

In summary, the S-1132B30-I6T2U Linear Regulator from the PMIC Voltage Regulators range is a simple, yet robust device suitable for a wide variety of applications. With a wide input voltage range, adjustable output voltage, current limit protection, and soft start circuitry, this device is the ideal choice for power supply designs that require low noise, low dropout, and high PSRR.
