The S-13R1F34-A4T2U3 is a Linear voltage regulator that is specifically used within the PMIC (Power Management ICs) field. It is a standby voltage regulator that primarily provides cost-effective voltage regulation within a wide input voltage range and is thereby suitable for a variety of applications. As a low drop-out (LDO) voltage regulator, this device is designed to regulate the output voltage with a maximum drop of 400 mV, making it suitable for use within applications involving low DC power and low noise.

Additionally, this voltage regulator is designed to give reliable voltage regulation while consuming very little electrical power and creating low noise. Low power design is achieved through an internal low power shunt regulator circuit that provides improved accuracy over a wide range of temperature and input voltage. The lightweight but robust design also allows this device to be used within field applications with minimal heat dissipation.

The S-13R1F34-A4T2U3 voltage regulator can deliver output currents up to 1.5A and offers adjustable output voltages from 0.8 V to 15 V. It also has a combination of a low internal impedance, a low output noise, and a low drop-out voltage, making it suitable for use within numerous PMIC applications. Furthermore, this device has a built-in thermal shutdown and over-current protection features that help to protect sensitive circuitry by automatically discharging excessive current.

For minimum external component count and enhanced safety, the S-13R1F34-A4T2U3 voltage regulator integrates feedback resistors, overcurrent circuits and input/output capacitors into the same package. The device also features very low ground current, inductive load transient response, fast lines response, and a low peak-to-peak output noise.

The working principle of the S-13R1F34-A4T2U3 voltage regulator is based on a very simple design. It is equipped with an internal PNP-type voltage reference and an amplifier connection, which is then followed by error amplifiers and transistors. The feedback control loop further helps to maintain the output voltage at the desired level. At its heart is a PNP bipolar junction transistor that provides the regulation in case of fluctuations in the output voltage. The current limiting feature incorporated in this device helps to prevents any damage that may be caused by a sudden rise or drop in the voltage.
