JAJSOF1C December 2022 – June 2024 TPS7A21-Q1
PRODMIX
Any internal noise at the TPS7A21-Q1 reference voltage is reduced by a first-order, low-pass RC filter before being passed to the output buffer stage. The low-pass RC filter has a –3dB cutoff frequency of approximately 0.1Hz. During start-up, the filter resistor is bypassed to reduce output rise time. The filter begins normal operation after the output voltage reaches the nominal value.
