TPS728180285YZUT

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

The TPS728180285YZUT is a single-output low-dropout (LDO) voltage regulator from the Texas Instruments TPS728 series. It provides a fixed output voltage of 2.85 V with a maximum continuous output current of 200 mA. The device operates within an input voltage range of 1.6 V to 5.5 V and features a typical dropout voltage of 230 mV at full load. It offers high power supply rejection ratio (PSRR) performance, typically 65 dB at 1 kHz. The component is housed in a DSBGA-5 package and supports surface-mount installation. It functions reliably across an extended junction temperature range from -40°C to +125°C.
