SBVS398A December 2021 – September 2022 TPS7A21
PRODUCTION DATA
Any internal noise at the TPS7A21 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 –3-dB cutoff frequency of approximately 0.1 Hz. 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.
