S-13A1G28-U5T1U3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The S-13A1G28-U5T1U3 is a fixed-output CMOS low-dropout voltage regulator manufactured by ABLIC. It provides a stable 2.8 V output with a maximum current capacity of 1 A. The device features high ripple rejection, typically 65 dB, and maintains a low dropout voltage of 230 mV. Operating within an ambient temperature range of -40°C to +85°C, it exhibits a line regulation of 0.05%/V and a quiescent current of 60 µA. Packaged in an SOT-89-5 surface-mount configuration, this positive polarity regulator ensures precise voltage control for power management applications.
