Product Overview
TPS7A20 is a Texas Instruments Power_Management IC described as a 300mA low-noise LDO regulator. Its recommended operating range covers 1.6 to 6.0 V input, 0.8 to 5.5 V nominal output, and 0 to 300 mA load current, with operation over -40 to 125 °C junction temperature.
The device emphasizes low-noise regulated output rails, with 7 uVrms noise specified without a noise-bypass capacitor and 7 uVrms output noise over 10 Hz to 100 kHz at 300 mA. PSRR is specified across several frequencies and load currents, including 95 dB at 100 Hz or 1 kHz under stated conditions and lower values at higher frequencies.
Package options include DQN X2SON-4, YCJ DSBGA-4, YCK DSBGA-4, and DBV SOT-23-5. Recommended external components include a nominal 1 uF input capacitor and 1 to 200 uF output capacitance, with 100 mOhm maximum output capacitor ESR. Internal enable and output pulldown functions support shutdown behavior in compact assemblies.
