TPS7A0512PYKAR

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

The TPS7A0512PYKAR is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It provides a stable 1.2V output with a maximum continuous current of 200mA. The device features an ultra-low quiescent current of 3µA and supports input voltages up to 5.5V. It incorporates comprehensive protection mechanisms including overcurrent, thermal overload, and under-voltage lockout (UVLO). The regulator offers a typical power supply rejection ratio (PSRR) of 40dB across the 1kHz to 1MHz frequency range. It operates within a junction temperature range of -40°C to 125°C and utilizes a compact 4-DSBGA package for surface-mount applications.
