S-13R1H28-N4T1U3

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

The S-13R1H28-N4T1U3 is a positive fixed linear voltage regulator from the ABLIC S-13R1 series. It provides a nominal output voltage of 2.8 V with a maximum output current capability of 150 mA. The device operates within an input voltage range of 2 V to 5.5 V and maintains operation across a temperature range of -40°C to +85°C. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 70 dB at 1 kHz, a quiescent current of approximately 9 µA, and a reverse current protection feature. The component utilizes CMOS technology and is housed in an SC-82AB surface-mount package.
