TPS7A2028PYCJR

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

The TPS7A2028PYCJR is a Texas Instruments ultra-small, low-dropout linear regulator providing 300mA output current. It features an ultra-low noise performance of 7μVRMS without requiring a noise-bypass capacitor and offers high PSRR of 95dB at 1kHz. The device operates with an input voltage range of 1.6V to 6.0V and provides a fixed 2.8V output with ±1.5% tolerance. It utilizes a DSBGA-4 package (0.612mm × 0.612mm) and maintains stability with minimum ceramic output capacitors.
