TPS728330185DRVT

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

The TPS728330185DRVT is a dual-output low-dropout linear regulator from the Texas Instruments TPS728 series. It provides fixed output voltages of 3.3V and 1.85V with a maximum continuous output current of 200mA per channel. The device operates within an input voltage range up to 6.5V and features a typical power supply rejection ratio (PSRR) of 65dB at 100Hz, decreasing to 40dB at 100kHz. It incorporates internal protection mechanisms including overcurrent limiting, thermal shutdown, and under-voltage lockout. The component is designed for surface-mount installation in a compact 6-WSON package measuring 2x2mm.
